Did not have much to do on his competitive Milan debut but showed plenty of promise to suggest that he could one day take up the mantle between the sticks.
Arguably the best defender on the night, the Argentine went some way towards redeeming himself after a nightmare season with arch-rivals Inter, winning a number of key battles.
Made a couple of important clearances as his athletic brand of defending helped his team register a clean sheet and ultimately all three points.
Charged up and down the right flank with great speed but let Silva creep in behind on occasions. Nonetheless, a standout performer thanks to his attacking prowess.
The experienced campaigner put in another accomplished display on the night, showcasing a fine array of passing and allowing his team-mates to regularly infiltrate the final third of the pitch.
Impressed in fits and spurts with the occasional turn of pace and eye for a pass but could not sustain his play. However, he showed plenty of positive signs to suggest a future partnership with Montolivo for many years to come.
Similar to Abate on the other flank but not nearly as consistent. Still, his dominance of the left wing forced Pereyra inside on numerous occasions.
Hustled and bustled his way through proceedings, although his passing let him down at times, before running out of steam and being replaced by Nocerino late on.
Milan's most productive player in the first half, the Slovene was duly rewarded for his efforts with a superb early winner. Showed some more neat touches before going off to a standing ovation.
Cut an isolated figure an attack and was lucky to have lasted so long. Although service initially came at a premium, he did not do enough to involve himself in the game, while his first touch was off-colour.
The Brazilian's best Milan performance in quite some time. Started off slowly before coming to the fore with some dazzling footwork and imaginative passes to carve out openings for his team.
The Croat did not make too many stops but was nonetheless important in ensuring Udinese still had a chance late on.
Was commanding in the early stages with the odd defensive header but soon struggled against the fluid movement of Milan's attackers.
Began quietly before growing into the match and ousting Milan shirts off the ball. A composed performance from the Brazilian.
Was Udinese's most effective outlet in the first half, constantly coming inside and firing snapshots at Gabriel but did not contribute much in terms of overall team play. Unlucky to be replaced.
Formed a solid partnership at the back with Danilo and Naldo as his team conceded just the one goal. Did not make any telling mistakes in what was a disciplined showing.
Outclassed by the technical nature of Milan's midfield pairing of Montolivo and Poli and had nothing to show for his performance other than a cynical yellow card before being subbed off.
While he may have had a hard time diluting the adventurous running of Abate, he gave his fellow wing-back a headache with a series of overlaps but lacked an end product.
Did lots of tracking back and helped maintain a balance in the middle of the park for his team as they searched for an equaliser late on. Also released the ball quickly for potential counterattacks.
Extremely fortunate to have evaded a red card after escaping a string of fouls since being booked early in the second half. Did not run at his man enough, although he tried to execute a number of moves with his vision.
His renowned passing game was limited and as a result could not impose his creativity on the encounter. Nonetheless, he sent in a few testing set-pieces.
A. Di Natale
Not his best game against Milan but influenced the match to an extent. Could only show glimpses of his match-winning ability, including a stunning free kick which crashed against the bar.
Came on for the final 15 minutes and did more in his cameo than Matri did in the previous 75. Lifted the team with his mere presence as Milan successfully saw out the victory.
Was very lively for the short time he was on the pitch and forced through a couple of openings for himself. However, his shooting is in need of improvement.
