BARCELONA
Goal
Claudio Bravo: Did not have an awful lot to do aside from pick the ball out of his own net in the second period. Was let down by his defence this evening. (6/10)
Defence
Dani Alves: Spent most of the match attacking down the right, but the Brazilian was sloppy in possession of the ball. Crossing needed to be a lot better from the right-back. (6/10)
Jeremy Mathieu: Was caught out for the Celta goal, while he was untidy in possession. Has had a good season thus far, but found Nolito and Larrivey tough to contain this evening. (6/10)
Javier Mascherano: Again, the most steady of the Barcelona defence, but he did not step forward on enough occasions. Has outperformed Sergio Busquets in midfield in recent matches. (6/10)
Jordi Alba: Proved a threat down the left and set up Neymar with a brilliant cross in the second period, but the Brazilian rattled the crossbar. Far from his side's most disappointing player. (6/10)
Midfield
Sergio Busquets: Made a meal of a soft challenge from Pablo Hernandez in the first period, with that incident summing up his performance as a whole. Poor. (5/10)
Rafinha: Showed flashes of his undoubted talent, but struggled to produce an end product. Needed a little bit more from Busquets and Ivan Rakitic alongside him. (6/10)
Ivan Rakitic: Made such a strong start to the season, but has almost lost his way in recent weeks. Failed to have any influence on the match despite his team's dominance of the ball. (5/10)
Attack
Neymar: Hit the woodwork twice on what was a frustrating night for the Brazilian. Should have scored at least twice, but just could not find the back of the net for his side. (6/10)
Lionel Messi: Always a threat for Barca, but was another guilty of missing guilt-edged opportunities. Almost rescued his side a point late on, but saw his excellent free kick hit the crossbar. (6/10)
Luis Suarez: Had a positive home debut. Linked well with Neymar and Messi, but passed up an excellent second-half chance by firing a point-blank header straight into the arms of Sergio Alvarez. (6/10)
Substitutes
Xavi: Provided balance in the middle of the park, but could not link with his forward players. Still has a role to play for Barca despite his advancing years. (6/10)
Pedro: Entered with Xavi after 66 minutes, but failed to have any influence on the match. Gave the ball away too often and picked up a stoppage-time booking in the final act of the match. (5/10)

CELTA
Goal
Sergio Alvarez: Stunning performance from the goalkeeper, who made sensational save after sensational save at the Camp Nou. Neymar, Messi and Suarez were all denied on multiple occasions by the Spaniard. (9/10)
Defence
Hugo Mallo: Was caused a few problems by Neymar and Alba, but overall, had a strong night. Was not seen as an attacking threat, but made some crucial challenges, especially in the second period. (7/10)
Sergi Gomez: Put in an excellent display against his former club. Made a number of crucial blocks and was calm in possession of the ball. Barcelona might regret letting him leave. (8/10)
Gustavo Cabral: Was seen hugging a number of Barcelona players in the tunnel before the match, but they will not want to embrace him after an important defensive performance. (8/10)
Jonny: Star moment came in the first period, when he somehow diverted Messi's goal-bound strike onto the crossbar. Managed to keep Suarez quiet in a wide position. (8/10)
Midfield
Nemanja Radoja: Did not see too much of the ball, but was excellent without it. Dropped deeper and deeper as Barcelona turned the screw in the latter stages of the contest. (7/10)
Pablo Hernandez: Picked up an unfortunate booking in the first period and was the first Celta player to be changed in the second period. Ran out of legs after putting a lot into the first 45 minutes. (6/10)
Michael Krohn-Dehli: Given licence to roam in the middle of the park and thrived in that particular role. Was extremely intelligent in possession of the ball. (7/10)
Fabian Orellana: Had some bright moments in the first period, but did not really feature in the second half. That said, continued to put the work in for his team. (7/10)
Attack
Nolito: A thorn in Barcelona's side. Looked a threat each time that he had possession in the final third and set up Larrivey for his strike with a clever back-heel. (8/10)
Joaquin Larrivey: Caused Mascherano and Mathieu all sorts of problems with his size and movement in the final third, while he showed Barcelona how to finish with an excellent second-half goal. (8/10)
Substitutes
Borja Fernandez: Only made his league debut earlier this season, but showed maturity after being thrown on after 69 minutes. Brilliant in possession and helped his team defensively. (7/10)
Charles: Only had 15 minutes on the field, but could have scored twice. Headed over from close range, before forcing Bravo into a smart save late on. Impressive cameo from the Brazilian. (7/10)
Levy Madinda: Did not enter until the final moments, but won a vital free kick late on after running away from Pedro. (6/10)
