The final whistle goes and Man Utd have sealed a 2-0 victory over a spirited Crystal palace side to keep their hopes of reeling in the top four just about alive. It was Van Persie who made the breakthrough from the penalty spot after Evra was brought down by Chamakh, but the headlines will belong to Rooney after his excellent goal, which came just a day after he committed his future to the club.
Dann has a chance to grab a late lifeline for Palace from a free-kick out wide, but his glancing header travels just wide of De Gea's post.
Giggs flies in with a rash challenge to bring down a rampaging Ward, and duly receives a yellow card.
Palace are still full of endeavour as a ball is whipped over towards Gayle at the back post and Smalling has to get up to make the headed clearance.
Puncheon embarks on a direct run down the right before Palace switch it over to the left, where Parr's cross is headed clear by Smalling.
Januzaj escapes the attentions of his defender to fire off a shot from a tight angle on the right, but Speroni gets down to make a comfortable save.
De Gea has had a fine game today and his handling is again secure as he holds on to a shot from Bolasie which was well hit from 20 yards and bounced on its way through a crowded area.
Palace are still showing plenty of spirit as they try to battle back.. They win a corner and Vidic will have to be careful that he does not concede a penalty as he grapples with Jedinak in the centre.
Van Persie almost grabs his second of the afternoon as he wriggles away from his defender before crashing a fierce drive against the crossbar from a tight angle.
GOAL! Rooney celebrates his new deal in style with a fantastic finish to put Man Utd 2-0 ahead. Evra digs in a cross and Rooney, apparently effortlessly, rotates his body into position and shows expert technique to volley a first-time effort into the top corner.
De Gea keeps Man Utd ahead with a wonderful save, as he leaps to his left at full stretch to turn behind a curling 20-yard shot from Jerome which had been creeping inside the post.
Palace's first change of the afternoon sees Jerome come on for Murray, who has performed wonderfully on his return from injury.
A dazzling moment from Mata nearly results in a second for Man Utd as he skips away from his defender with a nimble piece of footwork and then has the awareness to lay the ball back to Fellaini. It is a good effort from the midfielder from 20 yards but Speroni is equal to the challenge with a decent save.
The onus is on Palace to come forward now and that could play into United's hands. The Selhurst Park faithful remain in good voice as they try to spur the team on.
GOAL! Van Persie steps up and confidently powers his spot-kick into the top corner. Speroni guessed the wrong way and dived to his right, and you can feel the relief of the United players as they celebrate.
PENALTY! Evra just beats Chamakh to the ball right on the edge of the area and is brought down by a late tackle. The referee is positioned perfectly and points to the spot.
Murray lets fly with a ferocious strike from distance but De Gea is not caught out as he makes a solid stop.
Vidic fails to control a pass in midfield and has to bring down Murray to stop a potentially dangerous counter-attack, and the referee has little option but to brandish a yellow card.
Mata, Januzaj and Rooney are all trying to get involved as they go searching for the ball through the middle, but there is still no way through Palace's resistance.
Januzaj produces a great piece of skill to bamboozle Ward but he cannot shake off the Palace right-back, who recovers to make a strong tackle.
A Fellaini pass goes astray as he tries to pick out Van Persie, with Palace showing no signs of losing their focus.
Man Utd find some fluency as Mata lays a short pass off to Januzaj, but his shot is blocked and Van Persie concedes a foul in his efforts to latch on to the loose ball.
Man Utd finally break out of their own half as a long ball is launched forward towards Van Persie. Delaney gets there first, perhaps fortunately, and it flicks off his head back into the arms of Speroni.
Ince slams a volley over the bar from yet another Palace corner, and moments later there is another chance for the hosts as Murray cushions the ball down in space and Puncheon hits it straight at De Gea from the edge of the area, all along the floor.
It has been all Palace so far since the restart and they win another corner, which has De Gea frantically back-pedalling to claw the ball away from under his crossbar.
Palace win a corner but Ward's delivery is too short and is booted clear at the near post by Rooney on the volley.
Man Utd have had to show a lot of patience already and there is further cause for frustration as Vidic fouls Murray to give away a free-kick in midfield.
Palace get us started in the second half, with the game still on a knife-edge at 0-0. There have been no changes at the interval.
The whistle goes for half-time and the deadlock remains unbroken. Man Utd have had the majority of possession and Fellaini had the best chance of the half, but Speroni has been largely untroubled. Palace are well organised at the back and have posed some problems on the break, without really building up any sustained pressure.
Man Utd win a free-kick 25 yards from goal and Rooney steps up. He manages to get his curling shot over the wall and down again, but it just flies the wrong side of the post and Speroni had it well covered.
Fellaini misses a glorious chance for Man Utd as he blazes high and wide from 12 yards after a slick attack. The Belgian had started the move with a pass out to Van Persie, whose cut-back was cleverly played on by Mata, but the poor finish leaves Fellaini hanging his head in shame.
Rooney tries his luck with a shot from distance after cutting inside in on his right foot. It is well struck and a rare effort on target, but again it is too central to trouble Speroni and he makes a routine save.
The physio has top come on to tend to Chamakh after he picks up a knock, but there are no major alarms and the Palace forward will be fine to carry on.
Fellaini thinks he is fouled and picks up the ball, but the whistle had not gone and so instead it is Man Utd who concede a free-kick in midfield.
Palace look threatening on the counter-attack once again as they commit a few more players forward, but Ince's left-wing delivery is too close to De Gea and he intercepts with a comfortable catch.
Ferdinand just loses his bearings for a fraction of a second and for a moment it looks like Murray might seize on the loose ball, but De Gea is out quickly to claim possession.
Januzaj squirms a pass through to the overlapping Evra but the Frenchman's cross is poor as it crashes straight into the side-netting.
Chamakh squanders half a chance for Palace as he finds himself unmarked in the area but only manages to glance a header straight at De Gea from Puncheon's left-wing cross. For somebody so strong in the air, he really should have made the keeper work much harder there.
The flag is raised for offside as Rooney tries to release Van Persie through the centre. It is a correct decision from the official, and the Dutchman's final shot is saved anyway as Speroni comes off his line to narrow the angle.
Mata has been a peripheral figure so far, trying to drift in from his position on the right to influence proceedings, but on this occasion he just runs out of room as he tries to dribble past his defender and takes the ball beyond the byline.
There are appeals for a penaltyas Mata raises a high boot and just catches Chamakh. Palace may have had a case, even if it would have been a soft penalty as there was not much contact, but referee Oliver waves play on.
Palace win a free-kick in a promising position and Man Utd make a mess of clearing their lines as the ball ricochets around in the area. The final touch appears to come off Smalling and De Gea is forced to make a smart stop down low to his right to turn it round the post.
Rooney's corner is cleared straight back to him and he chips an exquisite effort towards the far top corner. Delaney gets up well to keep it out with his head and Vidic can only nod over from the rebound.
Now Chamakh links up with Puncheon in attack as Palace try to take the game to Man Utd, but they do not have enough numbers forward and the danger fizzles out.
Chamakh has been revitalised since the arrival of Pulis at Palace and he is not afraid to work hard for the team, getting back to aid his defence.
Januzaj throws his hands up in frustration at a lack of options before drilling a fabulous cross-field pass towards Fellaini at the back post. He tries to flick the ball back into the centre but there is no support.
It is going to be a long 90 minutes for Palace but they do look menacing on the counter-attack with the pace of Ince and power of the front two.
The ball just bounces into Januzaj's arm as he controls a long pass and the whistle has already gone for handball by the time the youngster swivels and drives a fine finish into the bottom corner from 18 yards. Nice strike, but it is disallowed and there are no complaints.
Man Utd enjoy a spell of possession in the Palace half but are unable to make any inroads, with the home midfielders staying disciplined to help shield the defence.
Palace relieve the pressure as they get a free-kick in the Man Utd half, but Ince's cross is headed powerfully away by Smalling.
Speroni rushes quickly off his line to gather a loose ball before Mata can pounce, followsing some more bright play by Januzaj down on the left.
Man Utd have found a good rhythm here and are pinning Palace back inside their own half with some controlled possession.
Januzaj tries to pick out Fellaini with a fizzing left-wing cross and the Belgian manages to get there before his defender, but Palace are quickly on to the second ball and get it away to safety.
Smalling sends in a decent low cross from the right and Fellaini swings his leg at a first-time shot, but his timing lets him down as the ball loops harmlessly off the top of his boot and allows Delaney to make a routine clearance.
Januzaj combines nicely with Van Persie before dragging a weak shot off target from the edge of the area.
Rooney nods a long diagonal pass from Januzaj back towards Van Persie, who attempts a spectacular overhead kick but fails to connect with the ball. It shows that even the best players in the worls can have the odd embarrassing moment.
Palace have seen plenty of the ball in the early stages but they are quick to regroup when they lose possession, as Man Utd try to get a foothold in the game after a slow start.
Ward spots a chance to burst forward down the right as he links up well with Ince, but his shot from just inside the area is well blocked by Fellaini.
Ince wastes the chance to deliver an effective set-piece as his deep corner floats over the head of everyone in the centre and out for a goal-kick, prompting an apologetic gesture from the winger.
Man Utd struggle to string their passes together in the opening moments and there is an early sign of Murray's aerial threat as he goes up with Smalling and wins a corner for Palace.
Man Utd get the game started and let us hope for an exciting encounter at Selhurst Park, with a lot at stake for both teams.
Callum Bunting says: " I am predicting a Man U win here. Great team selection with our four big guns (Rooney, Januzaj , RVP and Mata) as well as no Cleverley! I am so happy that Rooney has his new deal as he is crucial to us getting back to the top. I would have to say 3-1 to United with RVP, Rooney and Mata scoring with Ince grabbing a consolation. However, this season nothing is assured with United."
Luke Emmerson writes: "Very strong team out for United today. Great to see Mata, Januzaj, Rooney and Van Persie starting. Great to have Rooney playing after signing his new contract. Also great to have Fellani back. Expect a very hard match. Palace have some good home support. But I'm going to go for a 3-1 win to Man Utd. Come on Utd lets push our way up the league. #InMoyesWeTrust."
Alan Semple writes: "Think this one will be a close game with one goal separating the teams. I don't think United will keep a clean sheet. Will go Palace 1-2 United."
Steve Anderson says: "Going to be very interesting to see how RVP, Rooney Mata and Januzaj play in the same team. Moyes needs to get Rooney further forward and needs Mata in behind the strikers as he doesn't do much out wide as was proved against Fulham. Still though a very decent team, you look at it though and realise it's a desperation as we have no creative attacking central midfielder. 3-1 United."
Chris Green from Huddersfield is the first person to tip the home side to come out on top: "Crystal Palace to win 2-0, with Puncheon and Chamakh scoring the goals."
Man of the moment Wayne Rooney looks set to be deployed behind Robin van Persie as he aims to celebrate his new deal by netting for the first time since Boxing Day. David Moyes makes three changes from the 0-0 draw at Arsenal, with Rio Ferdinand replacing the injured Rafael and Antonio Valencia making way for Adnan Januzaj. Marouane Fellaini starts his first game since December following wrist and groin injuries as Tom Cleverley drops out of the squad. Tony Pulis makes two changes from the Palace side that beat West Brom in south London two weeks ago as Jonathan Parr comes into the defence and Glenn Murray is named in attack for his first Eagles' start in more than nine months.

Ben from Cheam writes: "Needless to say that we (united) have to get 3 points today. Be interesting to see how he fits RVP, Rooney and Mata in the team because it didn't really work last time against Fulham. We need to push Rooney further forward and let Mata play in the hole as he is ineffective pushed out on the flanks. It's going to be a tough game with Palace looking to get lots of men behind the ball but we have to be patient and I'm sure the goals will come. 3-1 United, Mata to open his account."
Danny Young in York says: "As a United fan, I am over the moon with the new deal for Rooney. I am backing him on the pitch today as well, with him to be amongst the goals in a 3 or 4 goal win. The new deal may help start to turn the tide for United."
Wayne Rooney yesterday committed his future to United until 2019 after signing a lucrative new contract extension. The reported wages of £300,000 a week, which equates to almost £30 every minute, have been highlighted, but Rooney has preferred to focus on thanking the fans for their support and outlining his dreams of a successful future for the club. All eyes will be on the striker as he seeks to prove his worth and put in the type of performance that can inspire United.
Manchester United are currently seventh in the Premier League and time is running out for them to make up an 11-point gap on fourth-placed Liverpool and qualify for next season's UEFA Champions League. The Red Devils have also had a couple of weeks since their most recent fixture, a period in which they have travelled out to Dubai for some warm-weather training. They will now be desperate to bring a halt to a three-game winless run, having drawn with Arsenal and Fulham since losing to Stoke at the start of February, but one man in particular is sure to draw most of the attention today.
Riza Ferati writes: "Manchester United will clearly win with Mata & Rooney getting on the scoreline."
Crystal Palace: Speroni, Ward, Dann, Delaney, Parr, Puncheon, Jedinak, Ledley, Ince, Chamakh, Murray. Subs: Hennessey, Gabbidon, Dikgacoi, Bannan, Bolasie, Gayle, Jerome.
Man Utd: De Gea, Smalling, Vidic, Ferdinand, Evra, Fellaini, Carrick, Januzaj, Mata, Rooney, van Persie. Subs: Lindegaard, Valencia, Fletcher, Giggs, Kagawa, Young, Hernandez.
Dhanyal Javed is the first to get in touch, saying: "Can see this game being a tough one for Man Utd but they should come through. I'm going for a 4 0 win with Rooney (2) and van Persie and Evra."
Crystal Palace beat West Bromwich Albion 2-1 last time out to move two points clear of the relegation zone and continue their encouraging progress under Tony Pulis. The Eagles have now won three of their past four games and should be refreshed after a fortnight's break, but it remains so congested in the bottom half that there will be twists and turns every weekend.
