Former Arsenal midfielder Patrick Vieira was racially abused during today's clash at Fiorentina, according to Juventus team-mate Emerson.
Emerson said Senegal-born Vieira was abused by the home fans at the Artemio Franchi Stadium in his team's 2-1 triumph against the Viola.
"Vieira has been the victim of racist insults," said Emerson after the game.
"It's very sad to see that something like this still happens."
The claims come just a week after racism made an unwelcome return to the spotlight in Serie A after Ivory Coast player Marco Zoro of Messina was insulted in last Sunday's league against against Inter Milan and threatened to walk off in protest.
The latest incident will no doubt upset the Italian Football Federation, who had launched an initiative to combat racism with all games this week having a five-minute delay as a protest.
