The Champions League's final matchday brings high-stakes fixtures, with Napoli vs Chelsea emerging as the ultimate do-or-die clash. Antonio Conte's Napoli face his former club, needing a win to avoid elimination, while Chelsea require a result to secure a top-eight finish and skip the extra playoff round. The Diego Maradona Stadium will be a cauldron of pressure.

Manchester City's shock defeat to Bodø/Glimt leaves them outside the top eight, raising fears of a repeat of last season's playoff exit. With injuries to Josko Gvardiol and Rúben Dias, Pep Guardiola's defensive options are thin. New signing Marc Guéhi isn't eligible yet, forcing reliance on Abdukodir Khusanov and Max Alleyne for the crucial Galatasaray tie.

Other key matchups include PSG vs Newcastle, where the loser drops to the playoffs, and a potential Mourinho magic show as Benfica visits Real Madrid. Arsenal sit atop the standings, but the scramble for knockout positions is intense. The new 36-team format ensures every final group game carries significant weight, with big clubs like Napoli and City facing unexpected jeopardy.
