According to The Independent, Toure has called for anyone else to have seen the abuse to come forward, while UEFA have confirmed that they are investigating why referee Ovidiu Hategan failed to follow the protocol for dealing with such incidents, as well as charging the Russian club with racist behaviour of their fans.
Hategan is supposed to have stopped the game and asked for an announcement to be made to the Arena Khimki crowd asking for all racial chanting to cease immediately, the report said.
Hategan would then have the power to delay or even cancel the game if the chanting persisted, but on Wednesday night he simply continued with play, failing to flag up the incident at all, the report added.
CSKA have pleaded their innocence, claiming to be surprised and disappointed by the allegations, and have said that the noises Toure heard must have been booing in an attempt to put off the opposition, in particular Edin Dzeko and Alvaro Negredo, the report further said.
However, Toure said that he was not deaf and other people must have seen it too.
UEFA has announced that they will publish the findings of the investigation once the disciplinary case against the Russian club ends on October 30, according to the report.
