Serie A champion Juventus lost its perfect record Tuesday after being held to a scoreless draw at fierce foe Fiorentina in a heated atmosphere at the Stadio Artemio Franchi.

Fiorentina had the better chances and midfielder Adem Ljajic should have put it ahead when through one-on-one with goalkeeper Gianluigi Buffon.

Fiorentina forward Stevan Jovetic, Serie A's top scorer, hit the crossbar while his team also had a penalty appeal turned down.

Juventus extended its unbeaten streak to 44 games and moved three points ahead of Napoli, which hosts Lazio on Wednesday. Fiorentina is fifth in the standings.

Fiorentina and Juventus have had a fierce rivalry for decades, and the atmosphere in Florence was predictably hostile with Juve being loudly jeered throughout the game.
