Really had nothing to do outside of the routine as his defence took care of the little Milan could muster.
The defender did not always have a lot to concern himself with, but when called upon he did not put a foot wrong at the back, making a crucial block on a Kevin-Prince Boateng cross.
Barcelona’s attacking strategy meant that he was pushed high up the right flank even more than usual. He was very useful in stretching the defence, even though his team-mates were mostly outdone when competing aerially for his deliveries.
For the most part, he stood tall against the pacey threat of M’Baye Niang and Stephan El Shaarawy on the break, timing his challenges excellently. However he almost threw away his good work, as one catastrophic attempt at a header instead let the French forward through on goal for a shot that cracked off the post.
As usual, he offered a good attacking outlet on the left flank, and crucially he looked to quickly recover his defensive position whenever Milan looked to get forward on the counterattack. Produced an excellent tackle to stop Robinho from point-blank range, before storming forward to clip home the last goal of the game.
Seemed far more at ease in a midfield role, where his deeper positioning allowed him more opportunity to run at the defence. As ever, his link up play was world class. He set up Lionel Messi’s second goal and came close himself with a stunning half-volley that Christian Abbiati pushed onto the woodwork.
Somewhat below the scintillating level of the rest of his attacking team-mates, as he did not really come up with any decisive moments in a rather subdued display.
Often the first line of defence whenever Milan looked to spring forward on the counter. Stuck to his task and made it hard for the Rossoneri to attack through the middle, while showing great composure to make space for himself under pressure with a series of pivots.
At his best in just this type of scenario, where Barca completely monopolised possession. A lovely one-two with Lionel Messi opened Milan up for the first, while an equally splendid pass put David Villa’s goal on a plate. His poise was such that the Rossoneri eventually resigned themselves to letting him keep the ball, focusing their attentions instead on pressuring more advanced players.
Head and shoulders above the rest. The Argentine sensation scored two first-half goals of the highest quality to put Barca level on aggregate. But more than that, it was his absolute menace on and off the ball that really stood out as something special.
For the majority of his time on the pitch, he found it hard to cope with Milan’s sheer numbers at the back. But one excellent Xavi pass to free him in space was all he needed, and from there he curled a great finish into the far corner for Barca’s third goal.
Could do absolutely nothing about both of Messi’s goals, and pulled off two quality saves from long range efforts by Andres Iniesta and Xavi. His concentration slipped towards the end, however.
Had no match for Lionel Messi’s quick feet in the build-up to Barca’s second goal. The pace of the home side's attack was often too much for him to deal with, as he struggled when isolated.
Rather fortunate to escape an early penalty call for bundling over Pedro, and though he motored forward well when Milan were chasing the game, his end product was lacking.
Like his partner Philippe Mexes, he started well, but once Barca were in full flow, he did not present much of an obstacle. Looked on the verge of collapse at times.
Positioned as the main springboard for the Milan counterattack, but he did not pass the test in that regard as a lot of his distribution from deep failed to find one of his team-mates.
Put in a lot of effort in midfield, but one sequence, a giveaway soon after winning the ball, set the events of Barca’s second goal in motion. Ran out of energy after a while and was substituted around the hour mark.
His final touch in advanced areas was hit and miss, and a few accurate pieces of distribution were let down by some wasteful longer deliveries.
Ran his socks off, but most of his effort was in vain as Barca were simply too good in midfield. Left chasing shadows most of the time.
Did not appear mentally prepared for such an occasion, as he was guilty of surrendering possession nervously on more than one occasion. A missed lunge from him gave David Villa all the time he needed to stroke home the third.
S. El Shaarawy
His pace was the main threat for Milan going forward, but far too often the distribution towards him was frustratingly inaccurate. He did have two half-chances to get a shot at goal, but both times he fluffed his lines.
Alongside Stephan El Shaarawy, his pace and energy formed the main offensive strategy for Milan. He was well-marshalled by the likes of Javier Mascherano, but one slip up from the Argentine put him clean through, only to spurn his chance and hit the post.
