Manchester City midfielder Yaya Toure has said he has faith in the football authority Uefa to punish CSKA Moscow after some of their fans racially abused him during a Champions League match last night:
Thank you for your support! Hate or racism cannot affect me when so many people are showing me love and support on a daily basis!
I believe in football institutions, I know decision makers will take their responsibilties and show A RED CARD TO RACISM
Manchester City captain Vincent Kompany called on Uefa to act against racist chants, after Yaya Toure was racially abused by fans during a game with CSKA Moscow.
Manchester City's Yaya Toure was racially abused by fans from CSKA Moscow in a game this evening. The BBC reported that chants could be heard from some CSKA supporters in the Khimki Arena.
Speaking after the game he called for Uefa to do more to tackle racism from the stands. In an interview with Sky Sports News Toure said he told the referee fans were chanting racial abuse, and nothing was done about it. He said:
"Yes, of course I told him [the referee]. It was disappointing. We are always talking about no racism and they continue to do it again - it was unbelievable.
"I think Uefa has to be stronger, and hold all the clubs and all the fans that do that [responsible].
"As an African player, it is always sad when you hear something like that."
