The Escalating Cost of Russia's War in UkraineEvidence of Russia's poor performance in its war in Ukraine, both militarily and economically, has been mounting over the past week. The US Defence Intelligence Agency (DIA) has confirmed earlier assessments that Russia has lost territory it previously occupied in Ukraine, while Ukraine has managed to reclaim approximately 400 square kilometers in and around Dnipropetrovsk – more territory than at any time since late 2022.Russia's Military Setbacks and Economic StrainRussia has still made a net territorial gain in 2026, but its advance is slowing down dramatically. According to the Institute for the Study of War (ISW), a Washington-based think tank, Russia advanced by a net 104 sq km between January 1 and May 26, 2026, compared to its seizure of 1,619 sq km during the same period last year.Ukrainian President Volodymyr Zelenskyy reported that Russian casualties had increased to 145,000 this year, of which 86,000 were killed and 59,000 troops seriously wounded. Ukraine's Defence Minister, Mykhailo Fedorov, highlighted that this meant 179 Russian losses per square kilometre of advance, compared to 67 last year – a rate higher than what Russia is currently able to replace through recruitment.Russia's war is also becoming increasingly difficult to finance. Having exceeded its entire 2026 budget deficit allowance by April, and depleted its foreign exchange reserves, Russia has been drawing down gold reserves at an unprecedented pace. According to its Central Bank, Russia has sold 27.9 tonnes of its gold reserves this year, worth more than $4bn, leaving reserves at their lowest since the beginning of the full-scale invasion in February 2022.Shifting Battlefield Dynamics and StrategiesThe DIA attributed Ukraine's territorial gains to Russia losing access to Starlink satellite services used for targeting and counter-battery fire. Ukraine attributes its success to its strategy of interdicting Russian logistics through mid-range drone and artillery strikes, which Fedorov described as a programme called "Logistical Lockdown" designed "to scale up middle-strike and systematically destroy Russian capabilities at the operational depth."This Ukrainian tactic has prevented reinforcements of men and equipment from reaching the frontlines, diminishing Russia's superiority in depth of resources and mass. The effectiveness of this strategy was demonstrated when Kherson occupation governor Vladimir Saldo restricted movement along the M-14 highway connecting Mariupol, Berdyansk and Melitopol, due to the number of vehicles being struck there.On the defensive front, Ukraine received a significant boost when Sweden announced it would donate 16 Gripen warplanes to Ukraine, which would also purchase an additional 20 through the EU's Ukraine Support Loan in a deal worth $2.9bn. Zelenskyy noted that "Gripen fighters with appropriate weapons, in particular Meteor missiles, which destroy targets at a distance of more than 200 kilometres, will help us push back Russian aircraft" against the approximately 3,000 Russian glide bombs dropped weekly.Simultaneously, Ukraine continued its long-range strikes on the Russian oil economy, which funds the war. On May 23-24, Ukraine struck oil depots and terminals at Novorossiysk and Tamanneftegaz on the Black Sea, as well as military and industrial sites including the Metafrax Chemicals plant in Perm and the Taganrog Airbase in Rostov.Russia's Response and Escalation TacticsIn response to Ukrainian advances, Russia pursued its own aerial tactic of striking Kyiv through massive combined attacks of drones and missiles. On May 24, Russia launched 600 long-range drones and 90 missiles against Kyiv and surrounding areas, including 36 ballistic missiles. Ukraine managed to shoot down 91 percent of the drones and 81 percent of the cruise missiles, though those that hit damaged government buildings, museums, and a market, injuring at least 87 people and killing two.Russia framed these attacks as retaliation for what it described as a terror attack on a college in occupied Luhansk, which it claimed killed six students and injured 39. Ukraine's General Staff countered that it was a strike on a centre for Advanced Unmanned Technologies run by Rubikon, Russia's unmanned systems force.Russian Foreign Minister Sergei Lavrov informed his US counterpart, Marco Rubio, that Russia would begin striking "military sites" in Kyiv in retaliation, warning foreign citizens, including diplomats, to leave. Moscow specifically mentioned using its newest Oreshnik intermediate range missile in the attacks, which it has also forward-positioned in Belarus.Future Outlook of the ConflictThe current trajectory suggests that Ukraine's strategy of targeted strikes on Russian logistics and supply lines, combined with enhanced air defense capabilities from international partners, will continue to challenge Russia's military advances. However, Russia's demonstrated willingness to escalate attacks on urban centers and its deployment of advanced weaponry indicate that the conflict may enter a more intense phase.As Russia depletes its financial resources and struggles to replace casualties, its ability to sustain current operations may diminish. Conversely, Ukraine's increasing success in securing international military support and refining its asymmetric tactics could shift the balance further in its favor, though the long-term outcome remains uncertain as both sides adapt their strategies.

Eight students were taken into custody on May 29, 2026 following a fatal fire that engulfed a dormitory at a Kenyan school, killing several occupants. The arrests mark a swift legal response to a tragedy that has shocked the nation. Fatal Dormitory Blaze Claims Lives at Kenyan School The fire erupted in the student residence, rapidly spreading due to the building's wooden structure and limited fire‑suppression systems. Emergency services arrived within minutes, but the blaze had already caused multiple fatalities and injuries. Arrests of Eight Students Spark Legal Scrutiny Eight students detained on suspicion of negligence, arson, or other related offenses. Implications for School Safety Standards in Kenya The incident has reignited debate over the adequacy of safety regulations in Kenyan educational facilities. Critics argue that overcrowded dormitories, outdated wiring, and insufficient fire exits contributed to the disaster. Potential Reforms and Future Oversight Government officials have pledged a review of school infrastructure standards and stricter enforcement of fire‑safety codes. Civil society groups are calling for independent audits of all boarding schools to prevent similar tragedies.

Fatalities Spark Global Scrutiny of the Kambo Healing RitualThe kambo ceremony—an ancient Amazonian rite that applies frog secretions to skin burns—has claimed at least six lives in the past two decades, including the recent death of UK wellness coach Kristian Trend (40). The surge in high‑profile fatalities is driving governments and health experts to demand stricter regulation of a practice that lacks scientific validation.Recent Deaths Highlight Risks of the Frog‑Poison CeremonyIn April 2026, Kristian Trend died after a “cleansing ceremony” in the United Kingdom, reigniting media calls for a ban. Earlier incidents include:2008 – 52‑year‑old man in Brazil.2018 – Italian man with pre‑existing heart conditions.2019 – Australian woman Natasha Lechner (39) seeking relief from chronic back pain.October 2021 – Australian Jarrad Antonovich (death linked to a perforated oesophagus).2024 – Mexican actress Marcela Alcazar Rodríguez (33) during a cleansing ritual.These cases illustrate the ritual’s unpredictable physiological effects, ranging from violent vomiting and hyponatremia to sudden cardiac arrest.Known Mortality Figures and Regulatory LandscapeMedical literature now records six confirmed deaths associated with kambo worldwide. A 2025 review in *Cureus* recommended tighter regulation after documenting severe reactions. Current legal status varies:Brazil banned sale and marketing in 2004.Chile prohibits importation.Australia classified kambo as a poison in 2021.United States deems it illegal; a 2025 US embassy advisory warned citizens against use in Peru.In the UK, frog poison can be purchased but is not a licensed medicine.Public Health and Legal Implications Across ContinentsThe ritual’s spread into Western “wellness” circles—particularly in the UK, US, Brazil, and Australia—poses a public‑health challenge. Health agencies warn that the peptide cocktail in kambo can cause:Severe nausea, vomiting, and diarrhoea.Rapid blood‑pressure drops and fainting.Cardiac arrhythmias and potential organ toxicity.Hyponatremia leading to brain swelling or death.Indigenous leaders, such as Yamanawa chief Joaquim Luz, have condemned commercial exploitation, emphasizing cultural appropriation and safety risks.Prospects for Regulation and Consumer ProtectionGiven the mounting evidence, experts anticipate a coordinated push for:Standardized licensing of practitioners where the ritual is permitted.Clear labeling and prohibition of online sales of raw frog secretions.Public‑education campaigns highlighting the lack of clinical efficacy.International cooperation to monitor cross‑border trade of the toxin.If authorities act swiftly, the next wave of fatalities could be averted, and the balance between cultural tradition and modern health safety may be better defined.

French Prosecutors Launch Investigation into Flotilla Abuse AllegationsFrench public prosecutors have been instructed by Foreign Minister Jean‑Noël Barrot to examine claims that Israeli forces committed sexual violence, beatings and humiliation against French nationals during the May 19 raid on the Global Sumud Flotilla bound for Gaza.Details of the May 19 Interception and Alleged ViolationsThe Israeli navy intercepted more than 50 boats carrying activists from about 40 countries in international waters off Cyprus. Thirty‑seven French citizens reported “extremely violent”, “humiliating” and “dehumanising” treatment, including alleged groping, stun‑weapon torture and forced exposure to cold.Numbers Highlight Scope of the IncidentOver 400 people arrested in the raid.37 French nationals among the detainees.At least 15 documented cases of sexual abuse reported by the Global Sumud Flotilla.More than 50 boats from 40 countries set sail.Political Repercussions for France, Israel and International RelationsThe probe adds to mounting criticism from Western allies, with France summoning the Israeli ambassador and banning National Security Minister Itamar Ben‑Gvir from entering the country. Israeli officials deny any misconduct, but the allegations could strain diplomatic ties and fuel calls for broader accountability mechanisms.Potential Legal Outcomes and Future Diplomatic TensionsIf the investigation finds evidence of criminal offences, French prosecutors could pursue charges for torture or sexual violence, potentially leading to international legal actions or sanctions. The case may also prompt other nations to reassess their diplomatic posture toward Israel’s enforcement of the Gaza blockade.

The Sunbed Association's Misleading Claims The body that represents the UK's sunbed salons, the Sunbed Association, has been accused of providing false information on its website, claiming that a tan protects against sunburn. This claim has been disputed by several leading medical bodies, including Cancer Research UK and the British Association of Dermatologists. The Health Risks of Tanning Health organizations have challenged the accuracy of the information being disseminated by the Sunbed Association. The association's website claims that sunburn is "thought to be the main cause of melanoma" and that "if you avoid getting sunburned, the benefits of moderate sun exposure will far outweigh the risks." However, medical experts argue that a tan is a sign of skin damage and offers little protection against the sun. The Data Analysis Melanoma skin cancer is the fifth most common cancer in the UK, with 19,400 new diagnoses and 2,600 deaths every year. The NHS, National Institute for Health and Care Excellence, European Commission, and the US's Centers for Disease Control and Prevention and Food and Drug Administration all highlight the risk of tanning. The Impact Analysis The Sunbed Association's claims have been criticized for being misleading and potentially dangerous. Full Fact, a fact-checking organization, has stated that the association's website "contains incorrect health advice on tanning" and warns that "bad health information can be very dangerous." The Prediction It is likely that the Sunbed Association will face increased scrutiny and criticism from health organizations and fact-checking bodies. The association's claims have been disputed by several leading medical bodies, and it is unlikely that they will be able to justify their position with scientific evidence.

UK Study Reveals Air Pollution's Impact on Children's Lung DevelopmentResearch shows that air pollution is slowing the lung growth of children in the UK. Scientists tracked the lung function of more than 5,000 people who were born in and around Bristol in the 1990s. Their health was assessed from birth onwards and their lungs were tested as they grew up, at eight and 15 years old and then as adults, aged 24, when their lung function should have reached its maximum.Longitudinal Study Tracks Lung Function From Birth to AdulthoodProf Ann Hansell, of the University of Leicester, who led the study, said: "Much of the evidence on health effects of air pollution relates to adults or pregnancy, but we think it's highly plausible it has impacts on growth and development of children. Those whose lungs didn't grow to maximum potential in childhood may be more vulnerable to the respiratory diseases of later life because they have a lower reserve."Dr Katie Eminson, also of the University of Leicester and a first author of the study, explained: "Lung function was measured using spirometry by trained technicians. Participants were asked to take a deep breath in, then blow out as hard and as fast as possible into a mouthpiece. A machine measured both the amount of air they can breathe out and the speed of that breath, providing an indication of how well their lungs are working."Pollution Exposure Linked to Reduced Lung CapacityThe researchers calculated the children's air pollution exposure in each trimester of pregnancy and then for each year of early childhood. This included particle pollution as well as nitrogen dioxide, a gas that comes mainly from diesel cars and fossil gas boilers.Hansell noted: "We spent literally years creating the particulate air pollution exposure estimates in pregnancy and early life, including sourcing road traffic data from Bristol city council that are not available in the national database."The researchers allowed for other factors that can affect children's health, including premature birth, breastfeeding, parental smoking and home conditions including damp.They found that breathing more air pollution during pregnancy, infancy and early childhood can slow lung development all the way up to early adulthood. The greatest impact was during adolescence, which is the time when lung growth accelerates.Health Implications Extend Beyond Respiratory SystemThose with reduced lung function face multiple health risks. "They are also more vulnerable to poorer health generally," Hansell explained. "For instance, low lung function in adults is associated with the same level of risk of heart disease as having high cholesterol. Research has also shown that people whose lung health has been affected by air pollution may be at greater risk of heart disease."An earlier study found that air pollution was reducing the growth of children's lungs in east London. There, the average nine-year-old's lungs were between 90 and 100 millilitres smaller than they should be—approximately the volume of two hen's eggs.Studies on children in Sweden showed that lung growth increased when air quality improved. Reductions in air pollution might have also allowed the Bristol children's lung growth to return closer to normal rates.Call for Action on Air Quality ProtectionEminson concluded: "While the effects in individual children are small and unlikely to have immediate clinical consequences, they shouldn't be dismissed. Because lung function tends to track from childhood into adulthood, small differences early in life may have implications for long-term health. This reinforces the importance of reducing exposures and protecting children's environments."

The Rise of Recursive Self-Improvement in AIThe word "recursion" is the latest buzzword in AI circles. Two separate startups have taken on the name, and many more have started referencing recursive self-improvement (RSI) in their roadmaps. Like AGI before it, RSI has become a three-letter byword for a cataclysmic AI takeoff – even if there's still a little disagreement about what it exactly means.In basic terms, RSI refers to an AI system that can continuously upgrade itself. Once AI systems can manage the upgrade cycle better than humans, the process can become a closed loop, limited only by the compute power they can access, and humans are no longer necessary or even helpful.Scary or not, that's a vision that a lot of AI labs are eager to chase.Key Players Pursuing Recursive SystemsEarlier this month, well-known AI researcher Richard Socher launched the aptly named Recursive Superintelligence with RSI as an explicit goal. "Our main focus is to build truly recursive, self-improving superintelligence at scale," Socher told TechCrunch at launch, "which means that the entire process of ideation, implementation, and validation of research ideas would be automatic."A number of other prominent researchers are already chasing that same goal, hoping for a breakthrough that will make recursive self-improvement possible.One of the most prominent is Andrej Karpathy, a legendary figure from Tesla and OpenAI, who is using agent swarms to train LLMs on simple tasks for a project he calls Auto-Research. Karpathy has been unusually open about the project, tweeting about milestones regularly and making the building blocks available through a public GitHub repo. So far, the work has mostly been confined to making minor improvements on a GPT-2 scale model — as Karpathy noted in March, "It's not novel, ground-breaking 'research' (yet)" — but it's been enough to convince lots of other researchers to follow the RSI dream. And with Karpathy now working on pre-training at Anthropic, he will have plenty of opportunity to apply the idea at a larger scale.Adaption — founded by Cohere and Google alum Sara Hooker — recently launched a similar tool called AutoScientist in an effort to automate frontier training. Like Karpathy's auto-researchers, the system trains agents to make incremental improvements — but for Adaption, the goal is to make it easier to train a full-scale frontier model. If those same researchers start to push the frontier forward, the system could quickly spiral into something very much like RSI.Disarray founder Doris Xin drew more specific RSI interest when her self-trained machine learning agent took home 28 medals in a recent Kaggle competition, beating out many human-trained agents. As she sees it, the major challenge is reliability."I would argue, given infinite compute and infinite time horizon, we are already there," Xin told me. "I want to make an argument that this is not a creative endeavor, really. It's just a lot of meat-and-potatoes engineering."The Current State of Self-Improving AIThere's also plenty of evidence that the AI industry isn't very close to recursive systems in any meaningful way — and is still grappling with talking to a wary public about its progress. So Google CEO Sundar Pichai basically admitted in a recent podcast interview."It's a continuum, and we are all definitely making progress," Pichai said. "But in the way people describe RSI, that would represent a next level of acceleration and would have a lot of implications, but we aren't quite there yet."But the continuum includes an awful lot of self-improving AI systems.In January, one of Anthropic's lead programmers for Claude Code estimated that "close to 100%" of his team's code was written by the tool — a frank admission that Claude Code was literally writing itself.Just because engineers are using an AI tool doesn't mean the tool can replace them — but Anthropic seems to be getting close to replacing engineers too. In a recent survey tied to the Mythos preview, five out of 18 Anthropic engineers believed that, with harness improvements, this version of Mythos could soon substitute for an L4 engineer — a midlevel programmer who can take on involved projects without supervision.Still, there were some of the same weaknesses you might expect."Some of Claude's major reported weaknesses compared to an L4 include: self-managing week-long ambiguous tasks, understanding org priorities, taste, verification, instruction-following, and epistemics," the report reads.In other words, its weaknesses are everything involved with self-direction, which is the cornerstone for RSI. But sure, for everything else, Claude is ready to step right in.Expert Perspectives on RSI TimelinesJust like the AGI term before it, the AI industry also can't tell us how far away it is from showcasing a meaningful recursive system. When Georgetown's Center for Security and Emerging Technology assembled a group of experts to study RSI last year, the group found a major split in assessments — some expecting an imminent "superintelligence" style explosion while others expected slower progress and an eventual plateau. But all agreed that recursion made the future especially difficult to predict.Helen Toner, director of CSET and a former board member at OpenAI, told TechCrunch that simply using AI tools to do AI research isn't enough to qualify as RSI. "They're just using AI for as much as they can," Toner told TechCrunch. "And I think that is different from the classic definition of RSI, which is really that there are no humans needed."Toner pointed to a recent post by METR's Ajeya Cotra, which distinguishes different milestones on the path to the AI research takeover. One step, which Cotra calls "adequacy," would come when the system can still perform research after all humans are removed — even if the resulting research isn't as valuable or efficient. "Parity" comes when an AI-only system is as good at research as a human-only system. "Supremacy," the final stage, comes when an AI-only system outperforms a collaborative system between humans and AI.Ultimately, Cotra concludes that AI is very close to the adequacy threshold of being able to produce some work on its own — similar to the incremental changes made by Karpathy's Auto-Research system. "I wouldn't be totally shocked if you told me this milestone had already passed, and I expect it to happen in the next couple years," Cotra wrote.She was less clear on when parity will come, but once it does, she thinks it would "massively accelerate the pace of AI progress, leading to AI research supremacy within another year."The Challenges Ahead for Recursive AIWith so much of AI built on scaling laws, there's a strong tendency to think RSI will follow the same curve. Toner thinks that many of those pursuing AI research and development via RSI "think of it as a pretty smooth ladder, where you can just keep scaling up."But even if AI researchers are able to make incremental improvements like Karpathy's auto-researchers, there will be larger challenges in handing off the whole process of research. Toner put it in terms of the history of computing, which has seen human beings handing off more and more of the process while still directing things from the top."We went from machine languages to assembly language and compiled languages; you're getting further and further from the guts of the computer," Toner said. "But the human is still, in some intuitive sense, running the show."Moving beyond that paradigm will take significant challenges, both in engineering and alignment. But even with the massive investments happening, there's no infinite compute available — and the basic trade-off between human labor and machine intelligence will be hard to overcome.The Future of Recursive Self-ImprovementAs for a total recursive AI system of apocalyptic visions? The only thing researchers essentially agree on is that, like AGI, it's not here yet.

The Impeachment Inquiry South Africa’s parliament is set to launch an impeachment inquiry into President Cyril Ramaphosa over the “Farmgate” scandal, marking a new phase in a political crisis that continues to shadow his presidency. The Background of the Scandal The “Farmgate” scandal centres on the theft of large sums of cash hidden inside furniture at Ramaphosa's private farm in 2020. The case has raised persistent questions over the origin of the money and why it was concealed. The Investigation Process The Democratic Alliance (DA) party said on Thursday that the committee tasked with examining the allegations will hold its first meeting on Monday, following a ruling by the Constitutional Court, which revived the process. The 31-member committee will begin by electing a chairperson. The Political Implications Ramaphosa has denied wrongdoing in the scandal and has responded by challenging the process in court. He filed a legal application against an independent panel report that found preliminary evidence of misconduct, a move that could delay the inquiry. The ANC, which holds about 40 percent of seats in the National Assembly, has publicly backed Ramaphosa and retains enough support to block any impeachment vote, which requires a two-thirds majority. The Future Outlook The DA, the second-largest party in South Africa’s coalition government with the ANC, has maintained pressure on the president and said it will hold him accountable if wrongdoing is confirmed. The party controls only nine of the 31 seats on the committee, leaving room for opposition parties to shape the investigation’s direction as it begins its work.

The Tactical Chess Match of Champions League FinalIt would be easy to look at Saturday's Champions League final between Paris Saint-Germain and Arsenal and see it as a battle of attack versus defence, of beauty against pragmatism, of French elan against English doughtiness, as some sort of tussle for the soul of football. But it would not entirely be true. And where, after all, was the honour at Agincourt? In the vainglorious charges of the dashing French cavalry or the stoic defiance of the British archers arrayed, naked from the waist down, behind their defensive stakes?The final promises to be a fascinating tactical contest between two teams with contrasting approaches but complementary strengths. PSG's devastating wings, featuring players like Desiré Doué and Khvicha Kvaratskhelia, will test Arsenal's defensive resolve, while Arsenal's set-piece prowess could provide their route to goal.PSG's Dominant Possession vs Arsenal's Defensive ResilienceThe statistical comparison between the two teams reveals contrasting strengths. In the Champions League this season, Paris Saint-Germain have averaged 63.4% possession, higher than anybody apart from Barcelona; Arsenal's figure is 52.6%, the 11th-highest of the 36 sides who made the league stage. PSG's pass completion has been 89.3% to Arsenal's 85.7% (third-highest to 14th-highest). PSG have scored 44 goals to Arsenal's 29. But on the flip side, Arsenal have conceded six goals to PSG's 22 and won 13.4 aerial duels per game to PSG's 9.4 (sixth-highest to 29th-highest).These figures suggest that PSG will dominate possession, while Arsenal will likely sit deep and look to counter-attack. However, that was not how either leg of the semi-final between the teams last season played out: PSG shaded possession at the Emirates and Arsenal at the Parc des Princes as they chased the game.The Full-Back Dilemma for ArsenalThe biggest danger to Arsenal is probably a counterattack. Most opponents sit deep against PSG, especially in Ligue 1, but the evidence of PSG's wins over Chelsea, Liverpool and Bayern Munich is that they are lethal in transition. Arsenal cannot let Desiré Doué or Khvicha Kvaratskhelia get a run on whoever they have at full-back. Both are rapid, supreme dribblers and terrifyingly direct.Full-back is an issue for Arsenal, especially on the right. Ben White is out with a knee injury and Jurriën Timber is doubtful with a groin problem sustained against Everton in mid-March. Martín Zubimendi started at right-back against Crystal Palace but it would seem more likely that Cristhian Mosquera operates there if Timber has not recovered, if only because he is a more natural defender.Riccardo Calafiori has seemed Mikel Arteta's preferred option on the left. His role will be twofold: to stop Doué and to invert into midfield, particularly out of possession, to try to prevent the counter. It may be that Myles Lewis-Skelly is used ahead of Zubimendi alongside Rice, in part because he is familiar with playing at left-back and so could help double up on Doué, or would be comfortable covering for Calafiori were he caught upfield.Midfield Strategies to Counter PSG's WingsAlthough PSG have scored more goals from non-penalty set plays than Arsenal in the Champions League this season (eight to five), it probably is reasonable to assume that corners and free-kicks offer Arsenal's best chance of a goal. But to counter PSG's midfield dominance, Arsenal may need to embrace a more aggressive approach.The first leg of PSG's semi-final against Bayern was remarkably open, almost basketball-like in its end-to-end attacking. But that should not necessarily be regarded as characteristic. PSG can at times seem a little sloppy, too reliant on their attacking prowess, but their performance away to Bayern, when Fabián Ruiz returned, showed how effective PSG's midfield can be. And that means either that Arsenal have to sit deep and accept PSG will dominate the ball or that they need to ensure their midfield has a destructive edge.Lessons from Previous EncountersChelsea's success against PSG in the Club World Cup final perhaps offers, if not a template, then at least inspiration for how Arsenal can hurt the defending European Champions. Enzo Maresca's approach was asymmetric, using Cole Palmer almost as an inside-right, haunting the channel between Nuno Mendes and the left-sided centre-back while getting in behind the left-back wherever possible.On the left, Marc Cucurella regularly tucked into midfield, just as Calafiori surely will, with Pedro Neto tracking back almost as a wing-back to check Achraf Hakimi's thrusts in support of Doué. If Arteta sees things similarly, that is probably more of a job for Leandro Trossard than Eberechi Eze, who may end up on the bench if Arteta, as he surely must, prefers 4-3-3 to 4-2-3-1.Keys to Victory in Saturday's FinalThere is an irony in this. The stereotype of Arsenal this season has been of a defensive side reliant on set plays, but that is not entirely accurate; rather they are a side whose defensive qualities have been highlighted because of deficiencies of creativity and attacking quality. But to beat PSG, it may be that they have to embrace the narrative and be the side critics say they are.Arsenal's right-back situation remains critical. White links better with Bukayo Saka than any of Arsenal's other full-backs, and Timber is as tactically astute as any player in the squad. Unless Timber is fit, the right-back issue is likely to diminish them from a defensive and an attacking point of view.The final will come down to which team can impose their tactical approach most effectively. Can Arsenal's defense contain PSG's devastating wings, or will PSG's midfield dominance prove too much for Arsenal to handle? The answer will determine who lifts the Champions League trophy on Saturday.
