Manchester City midfielder Yaya Toure could be in hot water with the FA.
The Telegraph says the FA are reviewing photographic evidence which apparently shows Manchester City's midfielder Toure making an offensive gesture towards to Wolves fans.
The images, taken from television pictures and later circulated on Twitter, were taken shortly before half-time, while Man City were leading Wolves 1-0.
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 against Manchester United.
