David Trezeguet's close range finish and Maurizio Domizzi's own goal ensured three valuable points for Juve whose victory celebrations were tempered by what appeared to be a serious injury to dynamic Czech midfielder Pavel Nedved.

Former AC Milan midfielder Roberto Donadoni masterminded Livorno's shock 1-0 win over the defending champions. Donadoni took over as coach of the Tuscany outfit earlier this month and found himself up against his old club for the first time.

Corrado Colombo scored the only goal in the 28th minute for a gallant Livorno side who held AC Milan to a draw at the San Siro when the teams met on the first day of the season. AC Milan's misery was compounded by the late sending-off of defender Alessandro Nesta.

Juventus have 47 points from their 20 matches played, while AC Milan have 42, eight more than third-placed Udinese who crashed to a 2-0 home defeat to Calabrian side Reggina.

Sampdoria climbed up to fifth place after winning 2-1 win at Lazio where the visitors were two goals up after just four minutes. Paolo Di Canio missed a first half penalty for Lazio, who fell to 14th.

Roma moved up to sixth position after coming from behind to win 2-1 at Fiorentina, completing a league double over the Florence club.

Vincenzo Montella's 17th league goal of the season sealed victory after Antonio Cassano had cancelled out Enzo Maresca's opener.

Montella, who is Italy's leading scorer, three ahead of Inter Milan's Adriano, also scored the winner when the teams played in Rome back in September.

Palermo were held to a goalless draw at snowy Siena, while Valeri Bojinov's 13th league goal of the season gave Lecce a 1-0 home win against bottom club Atalanta.

Arturo Di Napoli's header 10 minutes from time sealed a 1-0 home win for Messina against relegation-threatened Parma.

Juventus took the lead in the 12th minute at the Delle Alpi stadium. Zlatan Ibrahimovic drilled a low cross from wide on the right and France international Trezeguet popped up at the back post to stab the ball in off the post.

Brescia found themselves further behind two minutes before half time. Swedish striker Ibrahimovic cut in from the left and his clever cutback intended for Trezeguet was turned into his own net by Domizzi.

Kaka struck the post for AC Milan before Livorno gained the upper hand at a rain-swept Armando Picchi stadium.

Dario Passoni pumped a free-kick into the visitors' penalty area and Jose Luis Vidigal's point-blank header was palmed away by Nelson Dida. AC Milan's defence were caught ball-watching as Colombo snapped up the rebound, slotting home from six yards.

On Saturday Obafemi Martins scored a late equaliser as Inter Milan salvaged a 1-1 draw at home to struggling Chievo.

Inter's 14th draw in 20 matches maintained their unbeaten league record but left them a massive 15 points behind Juventus.

In Saturday's early match Bologna boosted their chances of retaining their Serie A status with a precious 1-0 win at home to Cagliari.
