AC Milan manager Gennaro Gattuso backed his former manager Carlo Ancelotti in calls for teams to walk off the pitch if a player is racially abused.

Ancelotti, currently in charge of Napoli, witnessed his defender Kalidou Koulibaly being racially abused by Inter Milan fans on Wednesday and despite raising it with the match officials, and three separate stadium announcements calling for Inter supporters to stop, nothing was done during the game.

Koulibaly was subsequently sent off for sarcastically applauding the referee after picking up a booking and Ancelotti said after the match that should any of his players be subjected to racial abuse during a match, the team would walk off the pitch, even if it meant forfeiting the match.
