Athletic Club vs. Atlético de Madrid: LaLiga Matchday 4 Preview at San Mamés
Athletic Club Seeks Defensive Consistency Under Edin Terzić
Athletic dropped their opening two fixtures—a 2-0 defeat away to Barcelona and a 3-1 home loss against Sevilla—before stabilizing with a 2-0 away win at Balaídos against Celta, courtesy of first-half strikes from Álex Berenguer and Robert Navarro. However, defensive frailties remain an urgent concern for Terzić, with the team conceding nine goals across five total matches this season, including pre-season tests against Atalanta and Real Zaragoza.
San Mamés historically serves as a formidable fortress for the Basque club, and squad rotation will likely feature heavily in Terzić’s tactical setup. Winger Nico Williams has logged just 109 minutes across the first three league fixtures as his workload is carefully managed. In midfield, Iñigo Ruiz de Galarreta and Beñat Gerenabarrena must dictate the tempo to feed playmaker Oihan Sancet, who has registered eight shots without scoring in the opening stretch of the league season.
Atlético de Madrid Arrives Unbeaten and Powered by Álex Baena
Atlético de Madrid travels to Bilbao riding the momentum of an undefeated start, collecting seven out of a possible nine points in LaLiga. Diego Simeone’s side impressed in their last outing, securing a 3-1 victory at the Sánchez-Pizjuán where Álex Baena scored a brace and Ademola Lookman added a third before halftime, as reported by sports data providers. Baena has emerged as the creative heartbeat of the colchoneros, contributing directly to goals in every league match so far.

Simeone has alternated between a traditional 4-4-2 and a 3-4-2-1 formation, with tactical indicators pointing toward the latter setup in Bilbao to neutralize Athletic’s threat down the flanks. Despite their strong form, Atlético will make the trip without forwards Alexander Sørloth and Julián Álvarez, both of whom remain unavailable due to fitness issues.
Betting Markets and Match Odds
