Gave Arsenal the odd scare with his kicking but his anticipation and shot-stopping gave his team confidence. Made an outstanding second-half save from Ibrahimovic and smartly thwarted Nocerino, both at 3-0.
A rock at right-back. Defended with aplomb and supported Walcott cleverly.
Made some fine last-ditch tackles but some of his wayward positioning should have been punished.
Made up for his first-leg shocker with an astute display as he refused to allow himself to be outsmarted by the power and touch of Ibrahimovic.
Began Arsenal's fightback by stealing a march on van Bommel to head home Oxlade-Chamberlain's sixth-minute corner. Defended with passion and quick thinking.
The night a superstar was born. His first-half display in central midfield was very polished; he set up the opener with his fizzing corner and brilliantly won the penalty for the third. Faded a little after taking a knock but proved that Arsenal might have a sensational player on their hands.
What did Arsenal do with the invisible man of the last three years? Outstanding distribution and imagination for an hour before his legs gave up on him. Precise finish for the second goal.
His energy and presence enabled Arsenal to dominate, particularly in the opening period.
R. van Persie
Slammed home as emphatic a penalty as you could see but this was not a night when Arsenal were reliant on Robin. He fizzed with menace but missed three good chances, including the gaping opportunity with only the keeper to beat at 3-0.
Hardly wasted a run or the ball in the first half but his African Cup of Nations exertions appeared to catch up on him after the break.
Not everything he did came off but sent shudders through the Milan defence every time he picked up the ball and began running. Looked Arsenal's most likely source of a goal in the second half until he limped off with seven minutes left.
One of the few shining lights - possibly the only one - for the visitors. Showed great anticipation and reflexes to deny van Persie on three occasions in open play. Could do little to prevent the three goals.
Summed up Milan's first-half complacency and incompetence but also their second-half shrewdness.
The right-back struggled to deal with the pace and verve of Arsena's attacks, although he did make some important interceptions.
Diminished his reputation with a rocky display. Handed Arsenal the second goal with an appalling clearance from Walcott's mis-placed cross.
Pitiful whenever Walcott put his foot on the pedal and accelerated towards him. Had the turning speed of a steamboat.
Sloppy distribution and slack in closing down the space for Arsenal to operate in.
M. van Bommel
The master of the dark arts was comfortably put in the shade by the energy of Arsenal's midfield after receiving an early booking. Failed to properly mark Koscielny for the opener.
An anonymous figure in central midfield for the first hour although he did become increasingly influential as the game wore on. His incredible failure to finish off a tap-in at 3-0 summed up Milan's incompetence.
Slow of action, feet and, seemingly, thought too. Showed once again he has little heart for the away-day battle.
Destroyed Arsenal in the first leg but reverted to type against English opposition with a generally tepid display, although he drew an excellent save out of Szczesny at 3-0 and always looked his team's most likely player to kill off the tie.
S. El Shaarawy
Had some bright moments but was generally unconvincing. Put clean through on goal on the brink of halt-time but was put off by the onrushing Szczesny and let off Arsenal with a wild finish. Withdrawn after 69 minutes.
