UEFA president Michel Platini has demanded an internal investigation into the alleged racist abuse of Yaya Toure by the CSKA Moscow fans on Wednesday night.
The investigation is into the failure to follow proper protocol in the aftermath of the abuse Toure received during the clash between Manchester City and CSKA Moscow.
UEFA have already charged the Russian club with the racist behaviour of their fans after Toure complained of monkey chants behind aimed at him.
They issued another statement on on Friday which read: "Further to the opening of disciplinary proceedings against CSKA Moscow following the alleged racist behaviour of some of their supporters at the UEFA Champions League match between CSKA and Manchester City FC on 23 October, UEFA president Michel Platini has requested that the UEFA administration immediately conduct an internal investigation to understand why the three-step protocol established to deal with incidents of a racist nature was not implemented."
Under UEFA rules: "If the referee becomes aware of serious racist behaviour, or is informed of it by the fourth official, he shall, as a first step, halt the game and ask for an announcement to be made requesting the public to immediately desist from such racist behaviour."
During Wednesday's Champions League clash, no announcement was made and the match continued.
UEFA said it would publish the findings of its investigation once the disciplinary case against CSKA had been dealt with by its independent control and disciplinary body on 30th October.
CSKA say they were "surprised and disappointed" by the allegations.
Toure even suggested the prospect of boycotting the 2018 World Cup in Russia following the match and has been backed by anti-racism campaigners.
