Current Form & Team News
Athletic Bilbao enters this Champions League opener with a mixed bag of recent results, albeit showing strong domestic form. Before the international break, they enjoyed a flying start to their 2025/26 La Liga campaign, securing three consecutive victories against Sevilla, Rayo Vallecano, and Real Betis. However, their momentum was slightly checked with a 1-0 home defeat to Deportivo Alavés in their last outing. Athletic Club’s home form in the 2024/25 La Liga season was formidable, losing only twice on their own turf, showcasing San Mamés as a true fortress.
A significant concern for Athletic Bilbao is the fitness of key player Nico Williams, who sustained a muscle injury while on international duty and missed the Alavés match, leaving his availability for this fixture in doubt. Other key players for Athletic often include Oihan Sancet in midfield and Iñaki Williams in attack.
Arsenal, meanwhile, have carried their strong form from the previous season into the 2025/26 campaign. They currently sit second in the Premier League table with nine points from four matches. After a narrow 1-0 defeat to Liverpool, Mikel Arteta’s side responded emphatically with a dominant 3-0 win over Nottingham Forest. Arsenal had a nearly flawless Champions League group stage last season, with six wins and one draw, suffering only one defeat.
However, Arsenal also face injury concerns. Bukayo Saka remains sidelined with a hamstring injury, and captain Martin Ødegaard picked up a knock in their recent match against Nottingham Forest, making him highly doubtful for the trip to Bilbao. The Gunners, however, boast significant squad depth, bolstered by recent summer signings like Viktor Gyokeres, Martin Zubimendi, and Noni Madueke, who are expected to strengthen their attack and midfield.
Tactical Preview
Athletic Bilbao, under the guidance of Ernesto Valverde, typically employs a disciplined, high-pressing style of play, often setting up in a 4-2-3-1 or 4-4-2 formation. They aim to be compact defensively, forcing opponents wide and closing down central spaces. In attack, they can be direct, utilizing the pace of players like the Williams brothers to get in behind defenses, with Oihan Sancet often operating as an attacking midfielder to link play. Valverde’s side also shows tactical flexibility, with fullbacks inverting into midfield during build-up play to create numerical superiority. San Mamés is known for its intense atmosphere, which can provide a significant home advantage.
Arsenal, under Mikel Arteta, is renowned for its tactical fluidity, possession-based football, and aggressive pressing. While often deploying a 4-3-3, they are capable of shifting formations within games, building up as a 3-2-5 and defending as a 4-4-2. Their offensive strategy involves wingers drifting inside, full-backs overlapping, and midfielders interchanging positions to create overloads and vertical passing opportunities. Key to their system is their ability to win the ball back quickly after losing it and to exploit half-spaces. Despite injuries to key attackers, new signing Viktor Gyokeres provides a potent goalscoring threat, while Declan Rice and Martin Ødegaard (if fit) are central to their midfield dominance. Their defensive unit has consistently been among the best in the Premier League, showcasing strong individual defensive capabilities and collective structure.
The weather in Bilbao on September 16 is typically mild, so it’s unlikely to significantly impact the match. Travel fatigue could be a minor factor for Arsenal, coming off a Premier League match and an international break, but elite teams are generally well-equipped to manage this. The San Mamés pitch is known for being in excellent condition.
