Riccardo Montolivo sought to test the Napoli keeper early on, but his shot from distance flew just a few inches too high of the visitors' crossbar.

The away side took the lead with their first real chance of the game when Lorenzo Insigne was able to pick out Allan inside the area, leaving the midfielder to fire comfortably beyond Diego Lopez in the 13th minute.

The home stopper was called into action not too long after too, and he had to produce a strong save down low to prevent Gonzalo Higuain from doubling Napoli's lead.

Milan might have found a leveller before the break, but Luiz Adriano could not keep his header down as he sent an attempt over from Giacomo Bonaventura's corner.
