Denied Victor Sanchez with a superb one-on-one save with his legs which saved Barca from going a goal down against the run of play. Didn't have too much else to deal with but distribution was excellent as always.
Was lucky to escape a booking in the first half as he took out Sergio Garcia with a tackle from behind. Only had Sergio Garcia to deal with and he did so pretty easily as he had the Espanyol captain dominated aerially.
Had an awful first half in which he continually got into good positions down the right, but couldn't find any team-mates due to an awful final ball. Improved slightly as the match went on as his crossing improved and he struck the post with an unlucky volley.
Was employed out of position at left-back but didn't have anything to deal with defensively so was often available up top as an extra attacker. Was a little too reluctant to get beyond Neymar on the overlap, though.
Glided gracefully in and around the penalty area with penetrative dribbles but struggled to find a final product. Seemed to be slightly off the pace as on more than one occasion his passes went wayward.
Was neat and tidy in possession as always and his spraying of the ball from deeper areas was outstanding. However, his performance lacked the incisive threaded passes through the middle which are his trademark.
Was susceptible to making a mistake under the pressure of Sergio Garcia at times in the first half but recovered excellently and eventually marshalled the defence well. Worryingly limped off the pitch towards the end of the game.
Patrolled the area in front of the Barcelona defence with ease as he didn't have any player dropping into the hole to deal with. This resulted in him floating further forward but he was left wanting slightly as he got hunted down rather easily when in possession.
Formed an excellent bond with Dani Alves down that right-hand side and the Brazilian running on the overlap meant that he could drift inside and cause problems centrally. Grabbed the only goal of the match with his predatory finish at he back post.
Looked off the pace from the start and just didn't seem to be totally up for the game, whether it be mental or physical. Frustration lead to him trying to hard to do things himself but eventually succumbed to his fourth consecutive match without a goal.
Was Barcelona's biggest threat from the first whistle as he continually took the ball on pacey runs down the left-hand side and gave Raul a torrid time at points. Created the winning goal with a fantastic pass through the legs of two Espanyol players.
Kept his side in the match in the first half with a couple of accomplished but comfortable saves as he denied Neymar's curled strike and beat away Iniesta's superb volley.
Was extremely solid for the majority of the match and put his body on the line to block a number of strikes, most notably a Messi attempt from 10 yards.
Had his hands full with Alexis and the continually overlapping Dani Alves but will have Torje to thank as he had help all evening from his team-mate.
Was left for dead a few times by the pace of Neymar and allowed the Brazilian far too much room down the left to cut inside and get the assist for the opening goal.
Organised the defence superbly for the first 70 minutes of play as he instructed his colleagues when to press and when to hold. Also put in a number of important challenges on the edge of the box.
Was arguably given the most attacking license going forward but barely saw the ball in the position between the midfield and frontline, which made any potential link-ups difficult. Instead slotted in in the three-man central midfield and screened the defence.
Put in a fantastic shift all evening as his defensive responsibilities required him to continually match the overlapping runs of Dani Alves. Helped out his full back massively and didn't allow him to be outnumbered.
Should have been booked early in the first half as he brought down Messi with a nasty challenge on the edge of the box, but eventually earned his yellow after hauling down Iniesta.
Sat in front of the Espanyol defence nicely and just looked to intercept and screen any potential balls through, and did a decent job for the majority of the match. Attacking ambition was zero as he rarely ventured forward from his deep position.
Was always back helping out his full-back and didn't allow Barcelona to double up. However, his play going forward on the rare occasion he saw the ball was not good as he was poor at retaining possession and taking the pressure off his team-mates.
Did about as much as he could up top as he was horribly isolated as the lone striker with barely any support. Chased down every loose ball and even came close to equalising for Espanyol late on as he fizzed a strike just over the bar from a tight angle.
