The defeat was only Inter's second in the league this season and the first at home since April last year.

Inter stayed on 68 points, while AS Roma, which beat Empoli 2-1, has 64. Juventus is third with 58.

Camoranesi scored in the 49th minute and Trezeguet made it 2-0 in the 63rd with his 17th goal of the season, tying him for the league lead.

Inter midfielder Maniche scored in the 83rd to make it 2-1, and he also hit the post in injury time.

"We won, we wanted to win, we played well," Juventus coach Claudio Ranieri said. "I don't know if Inter has lost its stride, but we are in good shape and played well. We have to always play with this intensity and these tactics."

Inter was without midfielder Esteban Cambiasso due to a calf injury.

"Every game we lose a player to injury and this has had an effect on us," Inter coach Roberto Mancini said. "That said, we can do much more than we did this evening. There is no point lingering on this, we need to prepare for next weekend's game."

Inter had a few chance for an early lead, including when Dejan Stankovic hit the crossbar in the 18th and when goalkeeper Gianluigi Buffon made a diving save on a free kick by Cristian Chivu in the 34th.

"Today we showed that playing at the top at our possibilities, at 110 percent, we can beat anybody," Buffon said.

Inter goalkeeper Julio Cesar also made several key saves to keep his team in the game.

In Rome, Christian Panucci headed in the winning goal in the 63rd to lead 10-man AS Roma over Empoli.

Roma played with 10 men after the 57th when Simone Perrotta got a red card for pulling down Felice Piccolo from behind.

Empoli pushed for the equalizer but the Roma defense held firm with key saves from goalkeeper Alexander Doni.

Max Tonetto had put Roma ahead in the 36th after Francesco Totti passed with his heel to set up the goal. Sebastian Giovinco pulled Empoli even in the 50th.

AC Milan got a goal from Alexandre Pato in the 67th to defeat Torino 1-0. Pato's goal, his seventh in 13 Serie A games, kept Milan four points behind fourth-place Fiorentina.

Giampaolo Pazzini scored his eighth goal of the season in the 79th to lead Fiorentina over Lazio 1-0. Pazzini, who came on in the second half to replace Christian Vieri, also hit the crossbar.

Lazio had been playing with 10 men from the 40th after Massimo Mutarelli got two yellow cards in two minutes.

Massimo Maccarone scored in the 88th with a penalty kick and again in injury time to give Siena a 2-0 victory over visiting Parma.

Franco Brienza scored in injury time to draw Reggina even with Napoli at 1-1. Napoli went ahead in the 76th when Roberto Carlos Sosa knocked in a pass with his chest from Ezequiel Lavezzi.
