Match preview
Under Matarazzo’s guidance, Sociedad have come alive — the team is unbeaten in three straight matches, including a Copa del Rey triumph over Osasuna and a dramatic league win against Getafe. The Basques are once again showing late-game aggression, pressing, and character — all the qualities they sorely lacked in the season’s first half. While they remain in the lower half of the table, the gap from the relegation zone is widening, and the atmosphere around the squad is visibly calmer.
Oyarzabal and Guedes are once again leading the attack, with Mikel posing a particular threat — he’s scored more against Barça than any other teammate. There are few absences, but the injury to Óskarsson slightly shortens the bench depth. A key advantage for Sociedad is freshness: they played their Copa match a day earlier, while Barcelona risk being less rested after a hectic fixture list. The home ground could also play a part — Sociedad tend to play with more confidence in front of their fans.
Barcelona are on their best winning run in a decade — 11 straight victories, including triumphs over Real Madrid, Atlético, and the Spanish Super Cup. The Catalans have improved both in results and organization — under Flick, they’ve learned to squeeze out victories even when opponents create chances. One of the key men has been Raphinha, who returned from injury and already boasts 8 goals and 3 assists in 11 games.
De Jong is back, with Lewandowski and Pedri expected to start, and Cancelo may debut following his transfer. However, the defense is far from perfect: 8.43 xG conceded in 7 matches with only two goals allowed — a testament to keeper García rather than a rock-solid backline. Given the away setting and Sociedad’s potential on the counter, Barça could face challenges again, but their winning streak is a powerful boost the visitors will be determined to extend.
Probable lineups
- Real Sociedad: Alex, Gomez, Ćaleta-Car, Martin, Aramburu, Turrientes, Soler, Guedes, Mendez, Kubo, Oyarzabal
- Barcelona: García, Koundé, Cubarsí, Eric García, Balde, de Jong, Pedri, Yamal, López, Raphinha, Lewandowski
Match facts and head-to-head
- Barcelona have won the second half in 4 of their last 6 meetings with Sociedad.
- In 4 of the last 6 encounters between these teams, only one side has found the net.
- Mikel Oyarzabal has scored 4 goals against Barcelona — the best record among Sociedad’s current squad.
Prediction
Since the coaching change, Sociedad have become more organized and focused, especially in the closing stages. However, Barcelona are currently in peak form — 11 straight wins speak for themselves. The Catalans’ defense is still shaky, but their individual quality, squad depth, and psychological confidence should be enough to secure another hard-fought victory. Sociedad are capable of scoring, but it may not be enough to influence the final result.
