Patrick Vieira has been a key player in Juventus' great league form

Juventus opened an eight-point lead at the top of Serie A after Mauro Camoranesi struck an 88th-minute winner in a 2-1 victory at Fiorentina on Sunday.

David Trezeguet put Juve ahead only for Giampaolo Pazzini to level just before half-time with a superb header.

Fiorentina hit the woodwork three times and Juve coach Fabio Capello admitted a draw might have been a fairer result.

However, the match was marred by claims from Juve midfielder Emerson that his team-mate Patrick Vieira was racially abused during the match.

"Vieira has been the victim of racist insults," said Emerson. "It's very sad to see that something like this still happens."

The claims come a week after Ivory Coast player Marco Zoro of Messina was insulted in a league game against Inter Milan and threatened to walk off in protest.
