We didn't score at least one goal...They were better than us, and this is football."Further reflecting on the game, Xavi said:"The second goal was really bad for us. We are playing against Madrid....They are a great team....They showed their best level in the second half."The two top Spanish clubs have faced each other five times across competitions this season. While Xavi's team has won thrice compared to Ancelotti's team's two wins, this defeat at Camp Nou will be a hard pill to swallow for the Catalan club. They are now only active in La Liga.Xavi's side will next take on Girona in a La Liga clash on April 9. Los Blancos, meanwhile, will return to action on April 9 as they take on Villareal.
