Made one potentially calamitous mistake but Balotelli couldn't capitalise. Quick off his line to defuse dangerous situations.
Won important headers to deny Pazzini in the later stages and helped to keep Balotelli frustrated.
His physical presence was vital in keeping Balotelli quiet, as the former Real Madrid man dominated in the air and stayed strong.
Provided a few decent long balls from left-back in what was a solid debut performance from the defender signed from Saint-Etienne in January.
A solid performance from the wing-back, who only occasionally let Taarabt get the better of him.
Fortunate to score with a deflected effort that equalised for Napoli, before picking out a delightful assist for Higuain's second.
Unfortunate not to score - he had several excellent long-range efforts - while his power and pace caused problems.
Picked some excellent balls from deep in midfield as he helped to trigger several counterattacks. Bright and positive.
Took his two goals brilliantly and was a constant menace, making intelligent runs and getting in behind Mexes with ease.
Excellent in the first half, when his pace and trickery allowed him to provide several brilliant deliveries.
His dribbling ability caused a few issues for Milan and he was unfortunate to not find the net with a curling effort that nearly nestled in the top corner.
Made a few reasonable saves but was fortunate to see plenty of Napoli's efforts rocket straight at him. His handling was shaky.
A terrible display, as he was barely ever aware of the location of Higuain - and Milan suffered massively as a result.
M. De Sciglio
The young full-back failed to contribute offensively and really struggled to keep tabs on Napoli's pacey and talented wide players.
His pace didn't allow Milan to press and he didn't have the technical ability to trouble Ghoulam.
Was strong in the air and cleared plenty of dangerous crosses for the away side, being the only Milan defender who didn't disgrace himself.
Failed to contribute in midfield and really struggled at left-back, where he started the game. Mertens had the beating of him all match.
N. de Jong
Broke up play and made things occasionally difficult for Napoli, but couldn't do all of the midfield enforcing on his own.
Took his goal brilliantly, slotting home from just outside the box to give Milan a valuable lead. Always willing to take on his man.
An ineffectual performance from the Brazilian, who contributed nearly nothing, summed up by Balotelli's decision to berate his teammate for a shocking pass.
A frustrating game for the Italy international, who didn't receive much good service and was substituted as a result - where he spent 10 minutes crying.
Was brighter than the starting midfield options, managing to pick several decent passes to put Pazzini in behind.
Classy and positive, he linked midfield to attack with more coherence. Far better than Robinho, and helped Milan to threaten in the later stages.
Got in behind on several occasions but was thwarted by either good defending or goalkeeping.
