Palace almost pull a goal back but Christian Benteke's towering header comes back off the post.

Joel Pereira was beaten.

Matthew Willock stripped off to come on...

...but hold on.

Manager Jose Mourinho tells the youngster to get back to his seat.

Oops.

A battle of two giants.

United defender Eric Bailly and Palace striker Christian Benteke leap like two superheroes before shaking Old Trafford when they hit the deck.

The man in red comes off worse as he lands heavily on his knee - it looks like he may not be able to continue.

Wilfried Zaha takes a massage from the physio, gives his right shoulder a wiggle and is back on the pitch and back on the ball straight away for Palace.

A yellow card on debut for Scott McTominay as he clips the heels of Wilfried Zaha, who was embarking on a speedy run down the left.

Zaha clutching his right shoulder, he looks in a lot of trouble here.

The final half of the Premier League season is under way.

A year to the day since Manchester United beat opponents Crystal Palace in the FA Cup final.

Hit play to watch highlights of that match.

The smiles and chatter between Jesse Lingard and Paul Pogba as the half-time whistle went did not indicate there was any cause for concern over the pair being withdrawn with more than half the game remaining.

Manchester United manager Jose Mourinho is clearly looking towards Wednesday's Europa League final against Ajax.

Wayne Rooney is still there. One substitution left. Will he be replaced near the end to give him a personal ovation?

Josh Harrop's debut goal the highlight as Manchester United lead Crystal Palace at half time.

Another substitution for Manchester United.

Jesse Lingard makes way for Anthony Martial.

Europa League final in mind for Jose Mourinho.

Oh dear, bad news before the Europa League final?

Paul Pogba is being replaced just before half-time by Michael Carrick.

One to keep an eye on.

Man Utd 2-0 Crystal Palace

Smash.

Wilfried Zaha's eyes light up and he gets through on goal, but Eric Bailly has other ideas.

The Manchester United defender comes across with a full-blooded sliding challenge, taking the ball, Palace man and the Stretford End in one swoop.

They are going to have to reconstruct that bit of the stadium after that.

Luka Milivojevic's free-kick hits the wall and ricochets wide of goal.

Joel Pereira will be thinking this Premier League malarky is a piece of cake, he has still not had a save to make.

It is the first time we have seen Wilfried Zaha get a run at the Manchester United defence.

The former Red Devil weaves his way to the edge of the box and is brought down by Timothy Fosu-Mensah.

Palace have a free-kick in a dangerous position...

This lad is full of confidence and almost bags a second, but Josh Harrop's curling effort to the far post sails inches wide of Palace goalkeeper Wayne Hennessey's left-hand post.

Manchester United's lack of goals has been well documented this season.

That Paul Pogba effort means they have scored twice for the first time in eight games.

Incredibly, they have only scored more than two at Old Trafford in the Premier League twice this term, against Leicester in September and Sunderland on 31 December.

Just under an hour to add Palace to that list.

United are carving Palace open down the left-hand side and Paul Pogba is dictating the play by spraying passes around at will.

He clips in a ball to the feet of Jesse Lingard inside the box, but the United man is unable to find a team-mate with his pull back.

Palace earn their first corner.

It is whipped in viciously by Jeffrey Schlupp and United goalkeeper Joel Pereira elects to stay on his line.

It almost proves costly as visiting striker Christian Benteke comes steaming in, but fails to get a connection on the ball.

Any little touch and they were back in the game.

Palace up the tempo, looking to get back into the game.

Christian Benteke flicks the ball into the box for Patrick van Aanholt, but another brilliant Timothy Fosu-Mensah challenge defuses the danger.

Comfortable for United now and the youngsters can afford to take it easy and play their natural game.
