Manchester City midfielder Yaya Toure hit out at match officials after their FA Cup semifinal defeat to Arsenal.
Toure has even suggested it would be better to play without an official in Thursday's crucial derby against Manchester United.
He said: "I think the referees have to stop this. I am very disappointed. It is not the first time, there have been a couple of times.
"If we have to talk about referees, people are going to say 'we complain' but when we see the highlights, for me it is very disappointing.
"Maybe on Thursday we are going to have a better referee or maybe play without a referee - I'd prefer that."
