Almost paid dearly for a disastrous clearance in the first half, but also weighed in with a handful of excellent saves to keep the score respectable. Could do little on either goal.
Too often caught out by the movement of the Catalan front three in the penalty area, but made a handful of decent interventions when Barca threatened to run away with the match.
Equal to almost everything thrown at him by the dynamic Barca attack, although his hesitance on Messi's cross cost dearly when Alexis notched the opener.
The Uruguayan was left to marshal the right hand side almost alone, and was given an extremely uncomfortable match as the likes of Alexis, Messi and Alba marauded down his flank.
Coped well at left back against the threat of Alves, making few mistakes and always marking diligently.
One of the best players in a Benfica shirt, threatened well from deep and put in a handful of decent crosses that troubled the visiting backline.
Ineffective in his efforts to try and lead Benfica's attacks from deep, and sacrificed for Aimar with barely an hour played.
Started brightly in the Estadio da Luz, his pace from deep causing problems in the Barca midfield. Faded after the break as the visitors took control.
A combative performance from the midfielder, who pulled no punches with a series of heavy tackles that eventually earned a booking.
Somewhat of a surprise to see the former Corinthians star pulled off at half time, after giving Barcelona several problems in the opening 45.
Was handed the best chance of the match for his team with a close-range effort, but could not steer the ball past the frame of Valdes.
Made a couple of key stops from Bruno Cesar and Lima in the first half to keep Barca on top. Stayed safe after the break to ensure a clean sheet.
His movement on the left alongside Alexis guaranteed a torrid night for Maxi Pereira. Always probing from deep, and given few problems at the back.
The speed of the hosts on the break obliged the Brazilian to take a more conservative approach to the game than is custom. Acquitted himself well at the back.
Showed no ill-effects from his recent injury lay-off as the club captain slotted in effortlessly alongside Mascherano in the centre of defence, but was then taken off in the second half after a sickening fall, and looks a doubt for the weekend match with Real Madrid.
Deservedly picked up a yellow for a clear dive in the first half. The most muted of Barca's front three, but worried Benfica when going forward.
An understated performance from the heart of the Catalan team, marked by an outstanding ball which almost led to a second for Alexis.
Reliable and intelligent as ever as the holding man, although at times stretched by the pace of the Lisbon side's counters. Will feel rather aggrieved to have picked up a soft red card in the closing stages.

A storming finish for his team's second capped a decent showing from the ex-Arsenal man, who was always a danger coming from deep.
Converted Barcelona's first with an instinctive close-range effort, and his link-play with Messi was a joy to watch at times. Could have netted more with a little more precision in front of goal.

The veteran playmaker was sent on for Perez, but could not inspire a comeback.
Could not turn the tide of the game in the second half after entering for the impressive Bruno Cesar.
There was no joy for the ex-Barcelona man against his former employers, after entering 15 minutes from the end.
