Chelsea boss Maurizio Sarri has called for Italian football to do more to combat racist chanting.

Napoli centre-back Kalidou Koulibaly was subjected to racist abuse from a section of Inter fans on Wednesday.

Ex-Napoli coach Sarri said, “You know that in Italy there are some problems in football.

“Especially for Naples, I think. When I was there we stopped two matches, One against Lazio in Rome and Sampdoria in Genoa.

“I am very sorry for Kalidou, because he is a wonderful man. I am really very sorry for him. I think in Italy We can do more for this problem."
