Real Sociedad vs Athletic Bilbao Predictions: Odds and betting tips for Copa Del Rey Semifinal - 04.03.2026

The storied Basque rivalry takes on elevated significance in this Copa Del Rey 2025/26 semifinal as Real Sociedad hosts Athletic Bilbao at the atmospheric Anoeta Stadium in San Sebastian. The match is set for 4 March 2026 with a late kick-off at 22:00 CEST a prime-time stage for one of Spain’s most compelling derbies. Both clubs arrive in identical form over the past thirty days (four wins, two draws, one loss), and this second leg promises not only a place in the final but also regional bragging rights.

Under Pellegrino Matarazzo, Real Sociedad have developed a methodical build-up, anchored by midfield orchestrator Benat Turrientes and the versatile Mikel Oyarzabal, both of whom are vital for transitions and attacking phases. For Athletic Bilbao, coached by the experienced Ernesto Valverde, attention must focus on Gorka Guruzeta up front and the relentless Iñaki Williams each a catalyst for Bilbao’s attacking forays.

A notable “hot stat”: Real Sociedad have conceded just one goal in their last three Copa fixtures, underlining a defensive discipline that stands out amidst the high stakes of knockout football.

Real Sociedad vs Athletic Bilbao predictions

My best bet: Under 2.5 Goals

In high-pressure knockout derbies, especially involving fierce rivals with organized defensive setups, goals tend to come at a premium. This fixture’s last five encounters yielded just seven total goals, and with both sides boasting structured midfields Real Sociedad’s Turrientes and Athletic’s Ruiz de Galarreta both excel in ball retention and tactical fouling expect midfield battles to stymie open play. The combination of recent form, historical head-to-heads, and defensive records leans heavily towards a tightly contested affair.

Real Sociedad average just over two yellow cards per game, Athletic a shade higher; both are prone to tactical fouling, especially in transition defense. Ball possession is balanced, with Real Sociedad’s more measured build-up contrasting with Athletic’s direct runs and crossing game. These respective styles imply prolonged spells without much penalty-area action, lending further weight to an “Under” prediction.

Real Sociedad vs Athletic Bilbao score prediction: 1-0

A single moment of quality likely engineered by the creative play of Benat Turrientes or the finishing touch of Mikel Oyarzabal will tip the contest for the hosts. Remiro’s consistency in goal, coupled with the tenacity of Elustondo and Zubeldia at the back, should prove decisive in neutralizing Bilbao’s Guruzeta and Williams. Given both clubs’ recent tendencies and their penchant for narrow margins, a 1-0 Real Sociedad result is my pick.

Pre-game odds and win probability: Real Sociedad the favourite

Bookies narrowly favour the home side, reflective of Real Sociedad’s greater consistency in both cup and league play over the past months. Under 2.5 goals is firmly odds-on, echoing the tactical chess match expected. The value on “No” for BTTS stands out in view of recent defensive records and historic trends in this derby. Athletic Bilbao’s price appeals as an outside bet but lacks weight against the hosts’ cup form.

Real Sociedad vs Athletic Bilbao Over/Under Analysis

• Four of the last five meetings ended under 2.5 goals.
• Both teams have averaged fewer than 1.2 goals per 90 minutes in their last five H2H matches.
• No match has gone over 3.5 goals in this rivalry in the last two seasons.
• Expect a high number of corners due to both teams’ wide play average of 10+ per match.

Real Sociedad Preview

Real Sociedad arrive buoyed by their 1-0 home win over Mallorca, a match that showcased disciplined defending and efficient use of chances hallmarks under Matarazzo. Prior to that, a 3-3 draw with Real Oviedo highlighted both creative flair and occasional vulnerability in transitions, but key figures like Oyarzabal continue to produce decisive moments. Their narrow Copa win over Athletic in the first leg underscores belief in their current system and their ability to withstand athletic, direct opposition.

Athletic Bilbao Preview

Athletic Bilbao’s latest run includes a gritty 1-1 away draw against Rayo Vallecano and tight victories over Elche and Real Oviedo. Gorka Guruzeta’s form in front of goal, combined with Iñaki Williams’ threat on the break, are Valverde’s most potent weapons. However, their narrow loss to Sociedad in the first leg places pressure on creative midfielders like Oihan Sancet to spark transitions and disrupt Sociedad’s compact lines. Expect Bilbao to push higher up the pitch, increasing risk but also the chance for a dramatic turnaround.
