Juventus fans again sang chants against Mario Balotelli on Wednesday just four days after racially abusing the Inter Milan striker during a Serie A match, Italian media reported.
Sections of crowd at Turin's Stadio Olimpico briefly chanted "Balotelli son of a .." in Wednesday's Italian Cup semi-final second leg against Lazio, the ANSA news agency said.
Juventus have been ordered to play their May 3 league game at home against Lecce behind closed doors after chants of "a black Italian does not exist" were directed at the 18-year-old.
Balotelli, an Italy under-21 international, was born in Palermo but is of Ghanaian descent.
Other fans in Turin sought to show they are not racist during Wednesday's Cup match, which Juve lost 2-1 to exit 4-2 on aggregate, by expressing their admiration for black footballers Edgar Davids, Clarence Seedorf, Juve's own Mohamed Sissoko.
"Davids, Seedorf, Sissoko, true champions, true idols," read a banner.
