Xavi admits Barcelona win came "at high price"
"It was a difficult game because they crowded the midfield. I am pleased with my goals, I am in good form. We will not concede any title, but we are better in the Champions League."
Barcelona president Joan Laporta also said: "I am sad, very sad for Leo. Also, for the team. He is a decisive player. We knew that he had some problems and for that reason he was rested at the Calderon.
"In the quarter-finals, any opponent will be difficult."
