If the FA's investigation finds that Toure was gesturing directly towards the Wolves fans, City could be without one of their most important players for next week's derby, because a clear precedent has already been set this season.
Toure was one of three City players named in the PFA's Team of the Year last night. His absence from Monday's night's showdown would infuriate Roberto Mancini ahead of what Sir Alex Ferguson called the "biggest ever derby" of his career.
“It is definitely the most important derby in my time at United,” Ferguson said. “We need to get a result at the Etihad, there is no question about that, we need to perform.
“But there is no reason why we can’t do that. There has been an expectancy from City that it could be their decider, but it’s our decider too.The game on Monday would always be a derby of highest proportions and it won’t be any different now.”
