Had no chance with Castro's goal, but saved well to deny N'Diaye earlier in the second half. Solid otherwise though did take some unnecessary risks with the ball at his feet.
Won a number of key tackles in the first half as he put in the standout display of the home defenders. Made sure Pique wasn't missed.
Was, as always, involved in an attacking sense, though never really got much of a sight of goal. Had to be on his toes in defence when Vadillo threatened.
Got forward well on the left but his final ball left a bit to be desired. Struggled to deal with Cedric's pace on the Betis right.
Tried to be too clever at times going forward but was a constant threat as he buzzed around the box. Allowed Castro to run off him too easily for the Betis goal.
Went close twice as he saw a shot saved by Adan before his second-half free-kick clipped the crossbar. Passed the ball well and made the odd key through ball.
Made some key challenges in midfield, though may have been fortunate to stay on the pitch when he brought down Vadillo in the centre circle in the first half.
Looked fragile at the back at times as the pace and strength of Betis' attackers saw him lose out in some key battles. Never got close enough to Castro for the goal.
At the centre of everything Barcelona did well, he nonchalantly stroked home the opener before sealing the points late on despite seeing his spot kick saved.
Heavily involved in the first half as he won a penalty with some fantastic quick feet inside the area. Faded in the second period.
Was very quiet out on the left before being replaced by Neymar for the final few minutes. The fact the Brazil international had more of an impact says it all.
Unlucky to end up on the losing side as he made some decent saves in the first half before keeping out Messi's penalty late on.
Lazy challenge allowed Messi to open the scoring from the spot and then saw his interception of Adriano's pass fly past Adan to double the hosts' lead.
Struggled at times with the pace of the Barcelona attack and picked up a second half booking for his troubles. Caused problems from attacking set-pieces.
Tasked with getting tight to Messi he saw little of the ball but had effective spells where he kept the little maestro quiet. Booked in the second half.
Pushed forward to support the attackers as much as possible and was unlucky to see his deflected effort well saved by Pinto. Physical approach shuck up some of the home defenders.
Pace caused problems for Adriano but was never really able to anything with it. Balls into the box were poor and he was outmuscled on more than one occasion.
Looked the most likely of the Betis players to score for the first hour as he twice tried his luck from the edge of the area. Surprisingly replaced in the second half.
Struggled with the pace of Sanchez in the first half as he was regularly chasing shadows. Set-piece delivery wasn't always that threatening.
Youngster saw the game largely pass him by on the left of the midfield three, though he did show the odd nice touch as the visitors came forward
Kept Pedro quiet on the Barca right, though was penalised for handball as Messi's spot kick led to the third and final goal.
Made an early run down the left that threatened better things but he struggled to get involved as players either side of him made more of an impact.
Gave the Betis attack a cutting edge it lacked until his appearance from the bench. Showed good composure to get the visitors back into it in the second half.
Showed some good touches in attack and helped link-up the midfield and attack after coming on midway through the second half.
