Did not have an awful lot to do before Barca put two goals past him in quick succession in the first half. He positioned himself excellently to deny Neymar with a double-stop during the second half.
The centre-back was far too static at times, allowing Barcelona in behind all too often. He failed to close Pedro as the winger ran through to score Barcelona's second, but he did stop him from adding a third just before the break.
Did a good job of frustrating Neymar during the early exchanges, getting very tight to him and limiting his impact. He also proved a positive outlet higher up the pitch and supplied some quality deliveries into the area.
Made a number of clumsy challenges and was fortunate to get away with one that ended Messi's game early. He was not alert to Neymar's movement for the opener and he was continually caught out playing too high.
Allowed Pedro far too much freedom on his flank and failed to track his runs in behind. He also allowed Fabregas to get round the back of him to assist the opening goal. He had a very disappointing game.
Struggled to really orchestrate the Betis attack, though he linked the play well during the first half. He narrowly missed the target soon after the break but was withdrawn in the 63rd minute.
Looked to use his pace to catch Barcelona on the counter-attack, and he supplied a great cross for Juan Carlos in the first half but Valdes saved. He faded into a peripheral figure after the break, though.
Made a number of strong challenges in midfield and did his best to disrupt Barca's play. He struck the post early in the second half with a brilliant effort but was withdrawn after picking up a booking.
Spurned a great opportunity early on as he headed over from 12 yards out. He struggled to get near to the ball in midfield and spent much of the game trying to chase down the Barca players in possession.
Could have scored with a decent header in the first half but Valdes somehow got to it. He failed to really use his pace to get in behind Alves and was sacrificed in the 67th minute for a more defensive option.
The striker showed some intelligent movement to find space in behind the Barcelona defence. He was denied by Valdes during the first half but eventually got on the scoresheet with a stoppage-time penalty.
The keeper made a couple of brilliant saves, denying both Molina and Juan Carlos during Betis' bright start. They proved crucial as Barca soon broke the deadlock. He provided a solid base at the back.
The Brazilian was unrelenting on the right flank, continually pushing forward to provide ammunition for the strikers. Hie supplied a great cross for Fabregas' second but conceded a needless late penalty which Molina converted.
Guilty of trying to do too much with the ball at times, he gave possession away cheaply when there really was no need. However, he helped limit the service to Molina for most of the game.
Was caught up the pitch early on and soon became more reserved. He allowed a few too many crosses into the box from his flank but supplied an assist for Fabregas' first in the second half.
The young centre-back put in a mature display, sweeping up at the back regularly. He made a couple of brilliant blocks, putting his body on the line to help his side keep another clean sheet.
A solid, if unspectacular performance from the midfield maestro. He knocked the ball about capably but only supplied a couple of real killer passes throughout the game.
A dynamic midfield performance from the Spaniard. He played some brilliant passes in midfield, linking with his team-mates effectively and also pushing. He assisted the opener and then went on to score a double himself.
Marshaled the midfield well, covering for the full-backs and making some decent challenges. Showed the other side of his game with a quality pass which was key to the opening goal.
Was frustrated with the physical nature of Steinhofer's marking but after breaking the deadlock with a simple finish he grew in confidence. His movement was impressive and he shouldered the responsibilities left by Messi's withdrawal.
Made a number of brilliant runs down the right flank, continually finding space behind Nacho to worry the Betis defence. He took his goal brilliantly in the first half and could well have had another.
