Barcelona defender Inigo Martinez shrugged off the jeers from his former Real Sociedad fans on Saturday.
Barca won 1-0 thanks to an injury-time winner by Ronald Araujo.
Martinez said of the boos: "I left here and it always hurts. It seems like they haven't forgotten.
"It has been difficult. La Real, we already knew that they are a team that plays very well. That they push at home. It has cost us a lot.
"These last 10 minutes we had more chances than in the entire game."
