Napoli supporters have been urged to wear masks of Kalidou Koulibaly against Capri on Sunday after the Senegalese defender was racially abused by Lazio fans in midweek.
The Serie A game between table-topping Napoli and Lazio at Rome's Olympic Stadium was halted for three minutes on Wednesday after the home fans aimed racist chants at the 24-year-old.
Lazio were fined €50,000 by Serie A's disciplinary tribunal and they will have to close sections of the Olympic Stadium for their next two home games.
Koulibaly took to Instagram after the match to "thank the Lazio players, but especially the referee [Massimiliano] Irrati for his courage" he wrote.
He added: "I thank my team mates, the public and our fans, who have been a great support against these ugly chants. I want to thank everyone for the messages of solidarity which I have received."
And he has received more support with Napoli supporters' group Quelli del Sangue Azzurro appealing to fans to wear masks at San Paolo stadium on Sunday.
A statement read: "Everyone in Naples is offended by what happened to our young star. Because of this, we want to show our full support to Koulibaly.
"We are all with you, Kalidou. Our invitation to Napoli fans is to print a photo of the defender and put it on your face when the teams come on the pitch."
