Kevin Prince Boateng and Robinho scored first-half goals as AC Milan beat Bologna 3-0 on Sunday in a convincing performance by the Serie A leaders.
Zlatan Ibrahimovic scored a third goal after half-time and Milan goalkeeper Christian Abbiati denied the hosts a consolation goal when he saved Marco Di Vaio’s penalty kick 12 minutes from time.
The win is Milan’s 11th of the season. Juventus beat Lazio 2-1 after Milos Krasic hit an injury-time winner.
Chiellini gave Juventus the lead in the second minute with a header from Alberto Aquilani’s corner, but Lazio equalized in the 14th after Juventus failed to clear a corner and Mauro Zarate slotted the loose ball home.
Lazio goalkeeper Fernando Muslera kept out Aquilani’s shot shortly after halftime and then in injury time, pushed Alessandro Del Piero’s freekick away for a corner.
But Krasic finally beat Muslera when he raced down the right and chipped the ball over the keeper to give Juventus the win.
AS Roma’s inconsistent season continued with an unconvincing 1-0 win at home to Bari.
Bari goalkeeper Jean Gillet stopped Francesco Totti’s weak penalty in the 20th, but 10 minutes later the Roma captain set up Juan for the only goal of the game.
Totti clipped a free-kick to the near post and Juan was left unmarked to guide the ball past Gillet.
Roma winger Jeremy Menez then skimmed the outside of the post with a low shot just before halftime.
After the break Bari limited Roma to shots from outside the area, but was unable to threaten an equalizer.
Bologna went close four minutes into the match. Gaston Ramirez shot from distance, but Abbiati palmed the ball away for a corner.
Boateng opened the scoring in the ninth after Ibrahimovic crossed from the left and the Ghanaian raced in to volley home from close range for his second goal in two games.
Boateng then turned provider for Milan’s second. He played a through ball to Robinho and the Brazilian held off Andrea Esposito to shoot low under Emiliano Viviano.
The goal was Robinho’s third in three league games and takes his league tally to six.
Ramirez again came close to scoring in the 56th but shot into the side netting after Abbiati had lost the ball outside the area.
In the 60th Ibrahimovic’s ninth league goal of the season wrapped up the win.
Andrea Pirlo played a ball over the top and the Sweden international was too strong for Miguel Britos as he side-footed the ball past Viviano.
Abbiati made two more stops before the final whistle.
First he dived low to stop Riccardo Meggiorini’s header at the near post and then after Clarence Seedorf brought down Di Vaio the goalkeeper dived to his right to save the Bologna captain’s attempt from the spot.
Also on Sunday, it was; Brescia 1, Sampdoria 0; Cagliari 3, Catania 0; Lecce 3, Chievo Verona 2.
