Racist chants: Man City referee should be banned - Kick It Out
The referee for Manchester City's game against CSKA Moscow should not officiate again after failing to deal with racist abuse, according to Kick It Out chairman Lord Ouseley.
City's Yaya Toure complained to Ovidiu Hategan about racist chants from CSKA fans during the Champions League win.
"The referee should not be refereeing again," Ouseley told BBC Radio 5 live.
"He failed to do his duty last night and that is a clear issue that Uefa should be dealing with."
Under guidelines issued in 2009 by Uefa - European football's governing body - referees have the power to try to stop racist chanting from supporters.
A referee can, as a first step, stop the match and ask for announcements to be made over the public address system.
The second step is to suspend the match for a period and, finally, to abandon it.
Since Toure reported the abuse to the referee during the game and spoke to him afterwards, the incident will be included in the official's report, which will be sent to Uefa on Thursday.
Manchester City have also lodged a formal complaint with Uefa, though the BBC's Moscow correspondent Steve Rosenberg said CSKA Moscow claim Toure was the only person to hear the chants.
Lord Ouseley, who heads Kick It Out, one of the leading anti-discrimination bodies in England, continued: "Firstly, why did the referee not do his job which was to stop the game and to make sure that problem was dealt with?"
Romania official Hategan, a Fifa referee since 2008, was also in charge when Lazio fans were found guilty of racist behaviour towards Tottenham players in the Europa League last season.
Ouseley added that the latest incident would also test new sanctions issued by Uefa.
In May it announced that in the case of racist incidents involving spectators a partial stadium closure would be applied for the first offence and a full stadium closure for a second, coupled with a fine of 50,000 euros (£42,800).
Three clubs have been had full stadium closures imposed this season, while five have seen partial stadium closures. Lazio had its case- for racist behaviour from its supporters in a match against Legia Warsaw last month - reduced after an appeal. The Italian club were ordered to play two games behind close doors last season for similar reasons.
"[Uefa] need to enforce the regulations that have been brought into play to deal with these type of offences and this will be a test for Uefa," Ouseley said.
"Will they do what they have always done and have sanctions that are applied in a way that will not stop this happening again? And if they don't do that, it brings the question: what are clubs going to do to protect their players? What is the union going to do to protect their players?"
Ouseley said that if players were not adequately protected, there could be more cases of them walking off the pitch, as when former AC Milan player Kevin Prince-Boateng forced the abandonment of a friendly match between his side and an Italian lower division team over racist abuse.
"It seems to me the only alternative is to provide them with the power to do what Prince-Boateng did last season with Milan and walk off the pitch because this is the only way we can bring sanity to the situation," he added.
"This has gone on for too long. Uefa and Fifa take us for mugs - and that can't go on any longer."
Culture, Media and Sport Secretary Maria Miller told BBC Sport: "Any form of racism in sport is absolutely unacceptable and I think any allegation of this sort needs to be investigated in full and Uefa needs to take it very seriously indeed.
"When countries like Russia are going to be very shortly hosting the World Cup [in 2018] it's important we know a tough line is going to be taken."
