Made an excellent save from Blind early on, tipping the midfielder's shot onto the post, but took a dreadful flap at Young's cross to allow Fellaini to nod in.
Given a good workout by Young, who weaved inside and outside from the left flank. Unlucky when he slipped in the lead-up to the first goal but generally did not get close enough to the winger.
Had few issues keeping a lid on Rooney and Falcao but silly to lean into the ball with his arm and give away a first-half penalty.
Dependable alongside Dann, not allowing Mata to peel inside behind the defence, although his distribution was a mixed bag.
Solid enough at left-back, although he often did not have to deal with a direct opponent as Mata turned inside.
Given license to push on in midfield and made the most of that freedom, winning the ball high up the pitch and getting into some dangerous positions in attack.
Given a simple brief of following Fellaini and marked the Belgian out of the game - until Speroni's flap at a cross to leave him with a simple finish.
Played his part in a very clever set-piece routine but did not have a great say on the game before being replaced by the livelier Puncheon at half-time.
Palace's biggest threat and might have scored, had the referee not blown up for soft foul in the build-up. Tore down both flanks and, while his final ball can be erratic, he puts teams on the back foot.
Had his moments but not as fearless as Bolasie and therefore less of a constant threat.
Did the simple things well, bringing others into play and turning balls into the channels for counterattacks, but should have beaten De Gea from close range.
His close-range stop from Murray was one of his best in an outstanding season. Could do little about Puncheon's deflected free kick but saved superbly again from Murray late on to preserve the victory.
Did not have too much chance to get forward due to the threat of Bolasie but did not fare badly against the winger before he was substituted due to a facial injury after 40 minutes.
Looks the most comfortable of United's centre-back options, particularly on the ball, but sucked in by Murray as Palace launched counterattacks on a couple of occasions.
Had to fill in at left-back after the injury to Shaw and, aside from one slip-up on the ball, he did a reliable job.
Like Blind, he used the ball well and his movement was good when United were on the front foot but struggled to shield the defence out of possession.
Passed and probed, combining well with Herrera, but has very little going beyond him to pick out. Netted his 10th of the season from the spot to give United the lead.
Uses the ball intelligently and tries to fill gaps in midfield but when Palace built up a head of steam the game sometimes got on top of him.
Largely anonymous with Jedinak tracking him but in the right place at the right time to nod in when Speroni missed a cross.
Made a couple of surges down the right but struggled to keep a handle on Bolasie at times.
Relentless in his attacks down the left and supplied the two crosses that decided the match, winning a penalty with one low whipped effort before Fellaini nodded in a higher delivery.
Struggled to get into the game and spent much of the first half hobbling before succumbing to a thigh injury at the break.
