Arsenal take on Athletic Club at the Estadio de San Mames in their first game of the 2025/26 Champions League campaign.
Mikel Arteta will be hoping that the summer’s £255m spending will yield even greater success in this year’s Champions League, with the club last year falling to a 3-1 aggregate defeat in the semi-final against eventual champions Paris Saint-Germain.
The Gunners have bolstered their squad with the likes of Viktor Gyokeres, Martin Zubimendi and Noni Madueke, while Eberechi Eze will be hoping to replicate his Crystal Palace form when he makes his European bow for his boyhood club.
Arsenal visit Athletic in their first game of the Champions League's league phase, with the Spanish side having qualified for Europe’s premier competition for the first time in 11 years.
And Ernesto Valverde’s men have the tools to punish their Premier League opponents, with their squad boasting highly-rated Spain internationals Unai Simon, Nico Williams and Oihan Sancet, as well as Nico's older brother Inaki.
Here’s everything you need to know on how to watch the Champions League encounter.
