Massimiliano Allegri's men registered a convincing 3-0 victory thanks to goals from Antonio Nocerino, Robinho and Antonio Cassano.

The opener came courtesy of Italy midfielder Nocerino, who finished off some fine lead up work.

Striker Zlatan Ibrahimovic found Alberto Aquilani with a long ball, and the midfielder nodded a pass across the face and into the path of Nocerino to tap in.

Robinho doubled their lead on 55 minutes when he finished off a perfectly-weighted through ball from Ibrahimovic.

After Cassano netted an Ignazio Abate cutback, the champions - now in 11th - cruised to a surprisingly comfortable win over fifth-placed Palermo.

Meanwhile, Inter Milan's struggles continued as they slumped to a 2-1 loss at Catania.

Esteban Cambiasso scored for the visitors in the first half, but Vincenzo Montella's men turned the tables with a three-minute double salvo from Sergio Bernardo Almiron and Francesco Lodi after the break, stunning Claudio Ranieri's men.

Catania moved into sixth on the back of the win, while Inter sit in 17th with just one win from their first six matches.

Elsewhere, Napoli suffered a 2-1 loss at the hands of Parma at the Stadio San Paolo.

After a rather uneventful first half, Massimo Gobbi and Giuseppe Mascara traded goals after the break.

But Francesco Modesto decided the encounter with a close-range strike seven minutes from time.

Napoli remain third despite the loss, while Parma have climbed into seventh.
