Massimiliano Allegri's side had to battle back from a goal down after Ciro Capuano fired the Sicilians ahead with a fantastic strike after 27 minutes.

Veteran striker Filippo Inzaghi cancelled out that strike on the stroke of half-time but the hosts failed to find a winner.

The draw leaves Milan two points off the leaders and level with Catania on four points from three games.

In today's only other match, Christian Ledesma went from villain to hero as he conceded a penalty before scoring an equaliser to help inspire Lazio to a 2-1 win at Fiorentina.

Fiorentina, still searching for their first league win, were ahead after 19 minutes when Ledesma clumsily brought down Alessio Cerci and Adem Ljajic converted the spot-kick.

Ledesma redeemed himself 13 minutes later when he turned in Stefano Mauri's clever pass before Libor Kozak scored after 69 minutes to seal a second consecutive win for the Romans.
