There are reports that Napoli fans will be banned from attending the Scudetto clash with Juventus on February 13.
There are currently two points between the clubs at the summit of the Serie A table, and they are due to meet in less than two weeks at Juventus Stadium.
However, widespread reports in Italy say that visiting fans have been forbidden from attending the match.
The ban is believed to be specific to fans who live in the Naples area, but there are still many Partenopei supporters living in Turin.
Juventus fans were banned from attending the first meeting between the clubs earlier this season at the San Paolo due to security fears.
