Juventus moved five points clear at the top of Serie A on Saturday as the champions beat Fiorentina 2-0 and closest challengers Napoli had to settle for a 1-1 draw at Lazio.
First-half goals from Mirko Vucinic and Alessandro Matri in Turin took Juventus to 55 points, with Napoli six points ahead of third-placed Lazio after Hugo Campagnaro's 87th-minute equaliser at the Olympic Stadium.
Vucinic opened the scoring for an aggressive Juve after 20 minutes, capitalising on Facundo Roncaglia's poor defensive header by smashing the ball home from just outside the area.
Matri doubled their lead four minutes before halftime after great work from Arturo Vidal, the midfielder evading four Fiorentina players before slipping in the striker.
Despite losing his right boot, Matri expertly slotted the ball past goalkeeper Emiliano Viviano to seal an easy win that leaves Fiorentina in sixth place.
Sergio Floccari netted Lazio's opener after 11 minutes when he controlled Abdoulay Konko's cross on the penalty spot and hit a fierce low drive past Morgan De Sanctis.
The home side deserved their lead against a below-par Napoli, after a first half of attacking football that Walter Mazzari's team couldn't handle.
Napoli, though, improved after the break, and got their reward when defender Campagnaro met a corner with a thumping volley that flew into the top right-hand corner.
Juventus 2 (Vucinic 20, Matri 41) Fiorentina 0
Lazio 1 (Floccari 11) Napoli 1 (Campagnaro 87)
