Quagliarella stars for Juventus

Fresh from scoring Juve's equaliser at Chelsea in the UEFA Champions League in midweek, Quagliarella guaranteed Massimo Carrera's men a fourth straight league victory with goals after 63 and 68 minutes.

The win sees Juve pull three points clear at the top of the table, although the teams below it have a game in hand.

In the day's other match, it was a tale of three penalties as 10-man Parma salvaged a last-gasp 1-1 draw against Fiorentina.

Viola defender Facundo Roncaglia scored his first goal with a stunning first-half strike before Jaime Valdes missed the chance to level from the penalty spot.

Aleandro Rosi then received his marching orders for the host two minutes from time, only for Stevan Jovetic to miss the resulting penalty.

Parma withstood a heavy onslaught, though, and was rewarded as Valdes redeemed himself deep into stoppage-time after substitute Luca Toni's handball.
