Arsenal return to the Champions League determined to start their campaign with authority as they travel to Bilbao to face an Athletic Club side in fine domestic form. After reaching last season’s semi-finals, Mikel Arteta’s men are eyeing a historic first European crown, and a statement win in the Basque Country would be the perfect opening note.
Arsenal – Confident & Ambitious
The Gunners arrive in Spain on the back of an emphatic 3-0 Premier League victory over Nottingham Forest. New midfield signing Martín Zubimendi was outstanding, scoring twice and running the game from deep, earning Player of the Match honours. Noni Madueke provided a constant spark on the right flank, completing the most take-ons and crosses, while striker Viktor Gyokeres netted his third goal in four league outings.
Arteta’s squad has been significantly reinforced after a summer spend close to £300 million, bringing extra depth and competition. Arsenal’s objective is clear: to better last season’s semi-final exit against eventual winners PSG and finally deliver Europe’s top prize. There is extra motivation, too — a win would set a new record of six consecutive European victories against Spanish opposition, after triumphs over Real Madrid, Girona and Sevilla in recent seasons.
Ernesto Valverde’s Athletic Club have begun the 2025-26 La Liga campaign brightly, sitting fourth with a record of 3 wins and 1 defeat. Their victories against Sevilla, Rayo Vallecano and Real Betis highlighted resilience and efficiency in front of goal, while their only setback was an unlucky 0-1 home loss to Alavés, decided by a Berenguer own goal.
The return of Aymeric Laporte has strengthened their defence, adding experience and composure alongside youthful energy in attack. Injuries and suspensions — notably Beñat Prados’ long-term ACL injury and Yeray Álvarez’s ban until spring — have tested their depth, yet the team’s mentality has impressed, grinding out tight games and responding well to pressure. San Mamés remains one of Europe’s most atmospheric stadiums, and Athletic will rely on their crowd’s intensity to unsettle the visitors.
Tactical Outlook
Arsenal will likely dominate possession, with Zubimendi orchestrating from midfield and wide players such as Madueke, Martinelli or Eze aiming to stretch Bilbao’s defensive line. Gyökeres’ movement in and around the box could exploit any gaps between Laporte and his partner.
Athletic are expected to counter through rapid transitions, using Iñaki Williams’ direct running to test Arsenal’s back line. Their pressing, particularly early on, may seek to disrupt Arsenal’s rhythm, while set-pieces could be pivotal at both ends given Laporte’s aerial threat and Arsenal’s quality from dead balls.
Prediction & Context
This clash promises a fascinating balance: Arsenal’s refined possession play and firepower against an Athletic side renowned for work-rate, structure and home pride. The Gunners remain favourites, but San Mamés seldom gifts victories, and Valverde’s team will view this as an opportunity to announce themselves in Europe.
For Arsenal, a professional display could set the tone for a deep run in the competition. For Athletic, upsetting one of England’s elite would underline their growth and prove they belong on the biggest stage.
