Real Sociedad moved to joint top of La Liga with a 4-2 away against Deportivo de la Coruna on Sunday.
Juanmi Jimenez opened the scoring after just three minutes from Xabi Prieto's cross, and a minute later it was 2-0 when Asier Illaramendi scored after Deportivo failed to clear a corner.
Adrian Lopez pulled it back to 2-1 when he scored on 27 minutes and Florin Andone continued the comeback in the second half by levelling in the 50th minute.
But Real Sociedad found another gear late on. Diego Llorente put them back in front with seven minutes left again following a corner before Illaramendi got his second three minutes from time to secure the points.
Barcelona stay top but only on goal difference from Real Sociedad with both on a maximum nine points from three games.
