Juventus could face a partial stadium closure after racist chanting was heard and reported in the win over Napoli on Saturday.
I Bianconeri came from behind to win the match 3-1 and go six points clear at the top of Serie A, but observers from the FIGC, who were stationed around the ground, reported unsavoury chants and language directed towards Napoli personnel.
The most serious of these saw racist language aimed at Napoli's Senegalese centre back Kalidou Koulibaly, who scored the winner in the same fixture back in April.
La Gazzetta dello Sport also reports that Partenopei manager Carlo Ancelotti was called a pig, an insult dating back to his time as Juventus manager between 1999 and 2001.
