AC MILAN opened their campaign with a classy 4-0 win over Lecce but it was another bleak day for defeated Juventus and the officials who wrongly awarded Napoli a goal in their 1-1 draw at Fiorentina.

Milan, third last term, had new recruit Zlatan Ibrahimovic in the San Siro stands and the former Inter Milan striker applauded when Alexandre Pato slammed in a 16th minute opener.

Swede Ibrahimovic was unavailable to new coach Massimiliano Allegri as he has not yet completed the formalities of his move from Barcelona but Milan did not need him as a promoted Lecce chased shadows.

Thiago Silva soon bundled in a corner and Pato netted again on 28 minutes by rounding the goalkeeper after a shrewd pass from Ronaldinho. Filippo Inzaghi made it four late on.

Juve lost 1-0 at Bari as their problems from last term were again exposed despite a spending spree. Substitute Massimo Donati blasted in for Bari with his left foot from outside the area two minutes before the break.

Sampdoria, knocked out of the Champions League qualifiers in midweek, beat Lazio 2-0 while Sicily’s Palermo drew 0-0 with Sardinia’s Cagliari.

On Saturday, last season’s runners-up AS Roma drew 0-0 with promoted Cesena.
