The Champions League group stage kicks off in style as Athletic Club welcome Arsenal to San Mamés on 16 September 2025. The atmosphere in Bilbao will be electric as the Basque giants return to Europe’s biggest stage, and their passionate supporters will expect a fearless performance against one of England’s finest.
Athletic Club will look to rely on their trademark intensity — pressing hard, playing with physicality, and using the energy of the home crowd to unsettle their opponents. Missing a few important players could be a setback, but their fighting spirit and unity make them a dangerous side, especially at home.
Arsenal, meanwhile, arrive as strong contenders for the trophy this season. Even with several injuries to key stars, Mikel Arteta’s team boast depth, quality, and European experience. The Gunners will aim to control possession, dictate the tempo, and use their pace in attack to break down Athletic’s defense.
This match promises a fascinating contrast: Athletic’s direct, high-energy approach against Arsenal’s composure and tactical discipline. If Arsenal can handle the early storm, they are likely to create chances and take control as the game goes on.
