Hardly required to touch the ball, never mind make a save. Did well to make the angle tight for Gayle's first-half chance but mainly a spectator.
Got forward well down the left as Mariappa failed to deal with him and Young. Went down too easily in the box early on, but, with United failing to sign Baines, he looked much more confident.
Looked slow and was twice shown up by Gayle and Guedioura for pace. Better strikers could have a field day against the veteran defender.
Solid if unspectacular from the skipper. Dealt with Chamakh with ease and barely broke a sweat.
Returned to the side for first time in over a year and looked like he'd never been away. Didn't get forward as much as his brother but assured in defence.
Tidy enough in the middle of midfield and played one superb ball to give Young an opportunity early in the second half. Substituted for Fellaini.
United's heartbeat and showed how effective he can be when given time on the ball. Vintage Carrick.
Diving apart, a decent display from the England winger. Won the first-half penalty and almost doubled the lead after the break. Crossing not always on target, though.
Gave United good options but rarely used by team-mates. Did put in some useful crosses but a quiet display from the winger.
The best player on the pitch and marked his performance with a sumptious free kick. The protective headband didn't inhibit him, though his goal celebration was far from effusive.
R. van Persie
Quiet for periods but then exploded into life towards end of the first half. Hit the crossbar before his expertly taken penalty calmed any nerves.
Kept busy throughout and made some good saves. Would have been a lot more than two if not for him.
Began on the left wing but watched the game pass him by for most of the first half. Moved centrally after red card but had little impact on the game.
Managed to keep Valencia quiet but unable to get forward and support the attack enough.
Solid and put in some crunching challenges on the edge of his own box. His Premier League experience showed in otherwise young line-up.
Run ragged by Young and then Januzaj. Not helped by the lack of support in front of him.
A good display as he kept van Persie quiet for large periods. Caught out of position a few times, however.
Gave the ball away for the opening goal and wasn't at his usual busy best. Palace needed more from their skipper.
Gave the ball away far too often and failed to support Mariappa at the back. Playing deeper than normal he never looked at home.
Early sending off put team-mates under pressure but little else he could do. Put end to number of the home side's attacks beforehand with crunching tackles.
Palace's brightest spark until second half substitution. Went close in first half and caused Ferdinand some problems.
Did most of his good work inside own box as he won a number of headers. Struggled at the other end and was booked before being replaced.
