Manchester City midfielder Yaya Toure called on UEFA to take action against CSKA Moscow after he was subjected to racist chanting during his team's 2-1 win in the Champions League.
Speaking Wednesday after the match in Moscow, the Ivory Coast player said he had told match referee Ovidiu Hategan about the chants during the game.
He said: "I spoke to the referee about it. It was quite disappointing. It was unbelievable and very, very sad to hear songs like that from the crowd."
Toure added: "I think UEFA need to do something strong. It would be nice if we could stop that."
City manager Manuel Pellegrini said after the match that "it was a pity and I hope we have the right measures."
