Xavi blamed the match officials for Barcelona's shock defeat to Espanyol last night.
Seydou Keita saw red during the 2-1 loss and Xavi rapped: "It was wrong.
"I am not saying there is a deliberate campaign against Barca, but we lost because of things beyond our control. The referee wrecked the match and also failed to allow the game to be played at a good pace.
"They should protect attacking teams. It's unfortunate that our opponents come here only to close up shop and not to play football."
