UEFA is investigating allegations of racist abuse against Manchester City's Yaya Toure and has warned that clubs will no longer escape with just fines if their supporters are guilty of discriminatory behaviour.
UEFA's communications director David Farrelly told Press Association Sport: "In relation to the UEFA Champions League match between CSKA Moscow and Manchester City, we are waiting for the reports from the referee and the match delegate as they are our eyes and ears at the match.
"UEFA now has new regulations in place which were brought in at the start of the season."
