Barcelona midfielder Xavi Hernandez is concerned that Atletico Madrid will know exactly how to stop the Catalans when they meet in the first leg of their Champions League quarterfinal on Tuesday.

The sides have already clashed three times this season, twice in the Spanish Supercup and once in La Liga with all three encounters ending in draws.

Barca took the spoils in the Supercup on away goals, but it is Atletico which leads the way in La Liga, a point ahead of second placed Barca, with just seven games remaining.
