A fine performance from the Brazilian goalkeeper as he generally coped well with what Barca threw at him. Almost pulled off a truly incredible double-save at the end, though Busquets' effort was just too powerful.
Looked solid throughout, letting very little past him as he enjoyed a good battle with Suarez. His performance was somewhat blotted by a blatant attempt to get Neymar sent off, though.
Probably the weak link in the Valencia team and he did not look particularly comfortable, with Jordi Alba in particular causing him some issues.
Another competent performance from the talented young left-back. Although he was grounded more than usual, he offered an occasional attacking threat and he battled away at the back.
Picked up a yellow card for a strong tackle on Neymar, but on the whole the German produced a good display, coping fairly well with Barca's dynamic front three.
The Algerian was quiet for much of the match as he struggled to get the better of Alba. Spurned a glorious second-half chance when one-on-one with Bravo.
Snapped away in midfield and helped to keep Messi quiet for periods of the match. Passed simply and allowed others to get in possession.
The Portuguese midfielder has impressed since signing and he was good again, appearing all over the place and causing problems with his late darts into the final third.
The creative hub of Valencia's midfield, he did find stamping his authority on the match something of a challenge against Busquets and Mascherano. But he was still a major influence in the hosts' moves.
Threatened sporadically on the left flank, though he did play a key role in two of Valencia's best attacks. Could have involved himself a little more on the whole.
The big centre-forward faded in and out, troubling Mathieu in patches and getting the Frenchman booked early on. Tested Bravo with a stinging drive in the second half, but he was not at his very best.
The Chilean was never going to be on the losing side as he pulled off a sting of excellent saves to keep Barca level. A well-deserved clean sheet.
The centre-back is enjoying a run in the team and he did little wrong again, producing a vital goal-line clearance in the second half.
The Frenchman was making his first return to the Mestalla since leaving and it was not one of his better displays, as he looked rather nervous, particularly against Negredo.
A constant danger in attack as the former Valencia man continuously bombed forward into the final third, giving Barragan a tough time.
The Brazilian did not look anywhere near as influential as usual, with his partnership with Messi nowhere to be seen. He was also caught out of position numerous times.
Surprisingly started alongside Mascherano in a rather defensive-minded midfield. The Spaniard's passing was typically accurate and he sealed the late win with an unstoppable close-range effort.
Used the ball well as part of Barca's double pivot and hassled Parejo to good effect, taking some of the sting out of his creative influence.
The aging midfielder's use of the ball was typically effective as he stroked it around well. He had little impact when Barcelona were chasing the ball, though.
Kept Otamendi and Mustafi occupied with his clever movement, but he was nowhere near his best and he ultimately lost his duel with the Argentinian defender.
Probably the liveliest of Barca's front three as he linked up well with his team-mates in the final third and ran at the Valencia defence. He failed to create too many problems in the area, though.
A very quiet evening for La Liga's all-time leading scorer. Although he played a role in the winner, he struggled to get himself involved and his impact was minimal by his usual standards.
With Parejo cramping up in the final 10 minutes, the Brazilian filled his void, though Barcelona were well on top by the time he arrived.
R. de Paul
Introduced in the latter stages as he replaced Rodrigo, though he impact was minimal.
Took the place of Negredo with eight minutes to go as he returned from injury, but he was not given the opportunity to make much of a difference.
Surprisingly left out of the starting XI and introduced with 21 minutes to go, replacing Mathieu. Kept Barca's moves ticking and he added another body in the final third.
Took Xavi's place for the final 10 minutes and looked neat on the ball as Barca desperately forced Valencia back.
Entered for Suarez in the last 10 minutes, but he barely saw the ball.
