Ahead of the latest weekend of European soccer, we pick out the must-watch matches from around the continent. We have the champions elite tackling the big-spending noisy neighbors, two irrepressible behemoths taking on fallen giants and a team hoping to make headlines back on the pitch after a tricky week. We are across the Premier League, Ligue 1, La Liga, Bundesliga, Serie A and Women's Super League as we preview the weekend's action.

Champions want to put challengers back in their place. Arsenal vs. Chelsea, Premier League Matchday 3, kicks off Sunday at 11:30 a.m. ET. With the transfer window shut, attention returns to the on-field action. Arsenal desperately wanted a superstar to bolster the left side of their attack, while Chelsea saw Enzo Fernández depart and thought they had a ready-made replacement in Lamine Camara, only for that deal to fall through. Arsenal have started life as champions with back-to-back victories. Mikel Arteta's side spent in the region of £195 million to bolster their squad. Over at Chelsea, Xabi Alonso's arrival has brought great excitement, with £400M accrued and £350M spent on new players. They have two victories from two under Alonso.

MY PREDICTION: Arsenal 2-2 Chelsea. Both teams are wonderful going forward, but Chelsea's defense has looked shaky given they've conceded five goals in their first two matches. Martínez's arrival will help there, while their front three of João Pedro, Rogers and Cole Palmer is already one of the most deadly attacks in the league.

Barça look to move on from the one that got away. Valencia vs. Barcelona, La Liga Matchday 4, kicks off Sunday at 10:15 a.m. ET. Barcelona travel to fallen giants Valencia, looking to continue their perfect start to the 2026-27 season. Without Álvarez, Barcelona haven't replaced Robert Lewandowski, but they still have an embarrassment of riches. Anthony Gordon has slotted into Catalan life nicely, while Raphinha occupies the striker spot.
