Carlo Ancelotti said he asked the ref to delay the match against Inter three times due to monkey chants directed at Kalidou Koulibaly. 

Ancelotti blamed Koulibaly's red card on the ref's inability to take charge of the situation, and said that his side were willing to forfeit matches if racist chants continued. 

“Announcements were made but the match continued. Next time we’ll stop the match by leaving the pitch, even if that means maybe forfeiting the match.”
