Uefa charged CSKA Moscow with “racist behaviour of their fans” on Thursday after Manchester City’s Yaya Toure complained of monkey chants against him during the Champions League match in Moscow.

Uefa said: “Proceedings have been opened against CSKA Moscow for racist behaviour of their fans (article 14 of the Uefa disciplinary regulations) and for setting off of fireworks (article 16) at last night’s Uefa Champions League group stage match in Moscow against Manchester City.

“The case will be dealt with by the Uefa control and isciplinary body on October 30.”

The Russian club have denied any racist abuse took place during Wednesday night’s match, but will face a disciplinary hearing next week.

In a further twist CSKA forward Seydou Doumbia, an Ivory Coast team-mate of Toure’s at international level, accused his compatriot of “exaggerating” what happened.

CSKA said that they were “surprised and disappointed” by the claims.

The club said: “Having carefully studied the video of the game, we found no racist insults from fans of CSKA. In many occasions, especially during attacks on our goal, fans booed and whistled to put pressure on rival players, but regardless of their race.

“In particular, this happened with Alvaro Negredo and Edin Dzeko. Why the Ivorian midfielder took it as all being directed at him is not clear.”

CSKA quoted Doumbia as saying: “I didn’t hear anything like that from the CSKA fans. Yes, they’re always noisy in supporting the team, and try to put as much pressure as possible on our opponents, but they wouldn’t ever allow themselves to come out with racist chants.

“So my Ivory Coast colleague is clearly exaggerating.”

Chairman of anti-discrimination body Kick It Out Lord Ouseley said that the latest incident would “test” Uefa’s new sanctions.

Ouseley claimed that referee Ovidiu Hategan should not officiate again because he failed to implement protocol when Toure made him aware of the abuse.

Under guidelines issued by Uefa in 2009, referees have the power to stop a match and ask for warnings to be made over the public address system.

If that fails to stop the abuse, they can suspend or even abandon a match.

After the match, which City won 2-1, Toure said he was saddened by the abuse.

He said: “I’m very, very disappointed about what those fans have done. I think Uefa has to take action because players with the same colour of skin will always be in the same position. For me, as captain, I was wearing an armband which said ‘no to racism’ and I was totally disappointed.

“I told the referee. It was unbelievable and very sad.”

Asked what action should be taken, Toure said: “Maybe they could ban the stadium, I don’t know, for a couple of years or a couple of months.

“We have to be as strong as possible otherwise they will continue like that. Too much is too much. We have to stop it now.”
