Yaya Toure was the victim of racist chanting last night, as Manchester City defeated CSKA 2-1 in Moscow. And Kick it Out chairman Lord Ouseley has called for the referee to be banned for his lack of support.
The Ivory Coast midfielder was targeted by certain sections of the home crowed for racist abuse, and despite reporting the offences to referee Ovidiu Hategen, no action was taken.
Under recent guidelines issued by Uefa in 2009, referees have the power to suspend and even abandon games should he feel necessary.
Match officials are able to first stop the game and ask for announcements to be made to the crowed regarding Uefa's anti-racism stance.
If the problem persists, the referee is able to suspend the game and, should the chanting continue, abandon the game all together.
Toure made it clear to last night's referee that the crowed were making racist gestures and chants, although the referee decided not to act.
And anti-racism campaign group Kick it Out are now calling for the man in question to be banned for his part in the affair.
Speaking to BBC Radio 5 live, chairman Lord Ouseley said:
"The referee should not be refereeing again.
"He failed to do his duty last night and that is a clear issue that Uefa should be dealing with," he continued.
Because Toure reported the abuse to the referee the sour incident will be included in the official's report and will be reviewed by Uefa today.
City have also lodged a formal complaint on the matter.
