Athletic Bilbao is set to host Sporting in a crucial UEFA Champions League fixture this Wednesday at their iconic home ground, San Mamés, affectionately known as "La Catedral." This match promises to be an intense battle as both teams aim to solidify their position in the prestigious European competition.

The "Rojiblancos" approach this encounter following a recent defeat in La Liga. In their last outing, Athletic Bilbao suffered a 2-1 reverse against Sevilla on January 24, 2026. The club will be eager to bounce back quickly and regain confidence for their Champions League challenge.

Meanwhile, Sporting arrives with high spirits after securing a victory in their domestic league. On January 24, 2026, the Portuguese side triumphed 1-2 over FC Arouca in the Primeira Liga, showcasing their ability to perform well away from home.

The last meeting between these two clubs saw Athletic Bilbao emerge victorious with a 3-1 scoreline on April 26, 2012. For this upcoming clash, the "Lions" will be without key players such as Yeray Álvarez due to a doping ban, and Benat Prados and Unai Egiluz, both sidelined with cruciate ligament tears. Sporting also faces the match with several significant absences, including Geovany Quenda (metatarsal fracture), Eduardo Quaresma (jaw injury), Nuno Santos (patellar tendon rupture), Matheus Reis (red card), Fotis Ioannidis (collateral ligament injury), and Salvador Blopa (calf injury).

Athletic Bilbao's last starting XI against Sevilla featured Unai Simón in goal, with Jesús Areso, Dani Vivian, Aitor Paredes, and Yuri Berchiche forming the defense. The midfield comprised Iñigo de Galarreta and Mikel Jauregizar, while Robert Navarro, Oihan Sancet, and Álex Berenguer supported the attack, with Urko Izeta leading the line. These absences and the previous formation will be crucial for the team's tactical approach.

This showdown at San Mamés is vital for both clubs' aspirations in the UEFA Champions League. Athletic Bilbao will look to leverage their home support to overcome their injury woes and secure a victory that boosts their European campaign against a Sporting side that arrives in good form and aims to cause an upset.
