Had little to do in the first half but a poor punch led to Parejo's goal. Was rarely called into action after that but dealt with whatever came his way.
A typically solid display by the Swansea defender, who tried his best to push his side forwards in search of an equaliser.
On the rare occasions that he did get forward, his delivery was excellent, but could not provide a consistent outlet.
Booked early on for handball but that did not affect him. Got forward as the game worse on and had a half decent chance with a header that flew wide.
A decent display by the Spaniard who showed no ill-effects after a nasty clash of heads with Jonas.
Swansea needed his invention playing in behind the striker but he simply could not get involved enough and struggled to make an impact against a disciplined Valencia defence.
A hard-working performance by the captain but found it tough going against a well-drilled Valencia midfield. Was replaced after an hour.
Worked hard in the first half but too often found himself outnumbered. Shifted flank in the second half but to little effect.
Showed show great passing at times and will feel aggrieved to see Vazquez's goal chalked off after his shot was spilt by Alves. Booked late on.
Showed pace down the left but, aside from one cross, could not provide any real threat for Swansea and was substituted at half-time.
Had a decent chance early on his powerful header was off target and went off injured five minutes before half-time, which will be a blow to Michael Laudrup with Michu still sidelined.
Looked a little shaky in the air early on and was lucky to escape two weak punches that flew straight at Bony. Fumbled a De Guzman shot in the second half and made a meal of a Pozuelo effort on the follow-up.
Was more than happy to get forward, bombing down the right, a useful outlet for the visitors.
The captain was an unflustered presence throughout, a performance that fully deserved a clean sheet. Hacked one off the line late on to preserve his side's lead.
Formed a great partnership with Mathieu that simply repelled anything that Swansea threw at them.
A feisty display, had a decent shot on goal just after half-time before being booked for a late foul on Rangel. Replaced by Postiga late on.
Lots of energy and made some bright runs beyond Jonas. Ought to have added a second after being sent clear through by Canales but clipped his shot just wide of Tremmel's post.
Had a hand in the goal, smashing Tremmel's weak punch back into the area, which was deflected into Parejo's path.
A very tidy display by the on-loan Chelsea man. Kept Pozuelo quiet, rarely gave the ball away and his decision-making was excellent.
Slotted home the only goal of the game with a calm finish after a fortunate decent. Another decent effort had Tremmel scrambling but picked up a booking for a late foul on Pozuelo.
Swansea found him an elusive presence. A silky touch and some great passes, particularly to set up Feghouli with a gilt-edged chance just after the break.
Not afraid to drop deep to seek out possession and worked hard all night. Had a decent shot that worried Swansea just after the break and was booked for a cynical foul on Taylor.
J. de Guzmán
Replaced Lamah at half-time and added more of an attacking threat in the second half.
A second-half substitute who injected a bit of urgency in Swansea's play. Called Alves into action with a low shot but could not beat the Valencia keeper.
Replaced Bony just before the break and thought that he had scored within minutes of his arrival only to see his effort, incorrectly, ruled out for offside. Went close again late on but his shot was hacked off the line by Mathieu.
