Napoli fans will throw their support behind Kalidou Koulibaly on Sunday.
Napoli fans will be wearing Koulibaly masks during Sunday's game against Carpi.
The Partenopei defender was the subject of racist chanting by Lazio supporters in Wednesday night's 2-0 victory at the Stadio Olimpico.
“The entire Neapolitan population feels offended along with its young champion," wrote the 'Quello del Sangue Azzurro' group of ultras.
“For this reason we want Koulibaly to feel all our affection and closeness. We are all with you, Kalidou."
