Barcelona have filed a formal complaint with Uefa about the refereeing of their Champions League draw at Paris St Germain on Tuesday.
The Catalans’ principle complaint concerns an incident where Javier Mascherano and Jordi Alba collided leaving both on the ground but referee Wolfgang Stark refused to stop play.
Barca assistant coach Jordi Roura said: “We have always respected the referees, but there is a point where there are very clear and concrete circumstances in which it is convenient to protest. If you don’t it is as if you don’t see the mistakes. We should not be taken for fools. So I think it is important to say something.
Barca added they did not consider themselves badly treated but were surprised that the referee didn’t know the rules of the game.
