Sergio Busquets was buzzing after Barcelona beat Real Sociedad 1-0 to win at Anoeta for the first time in 10 years.
"We're happy because it's been a long time since we won here," he said after the game.
"What I liked most was the image of the team, we were solid in defence and in attack and from there we have got a good result.
"We've got an advantage going into the second leg, but it's far from decided because they're a really good side.
"But it's a good result, especially keeping a clean sheet. "It was hard for us, the team sacrificed a lot. We've looked at what we've done poorly in other games against La Real and what we could improved.
"We knew how to defend and get a good result. We hope we can keep moving forward in the second leg, at home with our fans behind us."
