"Over the last couple of months Juan Mata has probably been Manchester United's best player. And his confidence showed with the way he took that penalty."

Wayne Rooney's deep cross from the right is headed down by Marouane Fellaini but Ashley Young is unable to steer his stooped header towards goal.
Palace are up against it.
Fraser McIntosh: The virus at United this week must have been bad. They all look as white as a sheet.
Mitul Patel: What's more silly? Wasting two hours of revision or watching United attempt to score.
Brandon Clarke: A win for Palace today and suddenly it's exciting to be a Liverpool fan again!
Sorry about that Brandon...

"It was a 50-50 decision, Scott Dann has tried to get his body in the way to stop the cross, but as a defender you have to be careful. Was it a deliberate handball? Not for me.
"But it was a great penalty from Juan Mata but in the last two or three minutes it has come against the run of play."
Image source, APWayne Rooney is on the pitch but Juan Mata takes responsibility.
The Spaniard takes a few steps back before coolly dispatching the opener. United know win today, coupled with a Liverpool defeat at Chelsea tomorrow, and Champions League football is theirs.
Ashley Young's cross from the left is deemed to be handled by Scott Dann, who leant into the ball. Penalty.
Image source, AFPSkills from Wilfried Zaha. The former Manchester United man jinks one way and the the other to leave Antonio Valencia standing on the left.
His cross heads towards Glenn Murray but United clear through Phil Jones.
United may not be on form but they have no problems with trips to the capital.
They have conceded just three goals in their last eight Premier League away games in London, keeping five clean sheets.
Another good effort as Ander Herrera's 20-yard shot screams wide. Good save by the ball boy behind the goal.

"What a wonderful save from Julian Speroni. Manchester United worked it very well but Speroni got the slightest of touches to take it for a corner."
Image source, Getty ImagesOut of nothing, United are almost ahead. Daley Blind picks the ball up 25 yards and his low strike is touched onto the post by Julian Speroni. Good effort.

"The key for Crystal Palace is their two wide men - Yannick Bolasie and Wilfried Zaha. Palace will let Manchester United come on to them but there is a lot of space behind Manchester United's defence and when you have the pace Palace have you can take advantage of that."
Shohidur Rahman: The fact that Palace have never beaten us in the Premier League makes me even more nervous that they'll beat us today.
Michael Devlin: Hope I'm proven wrong today, but I really don't like the automatic inclusion of Fellaini in the starting 11.
Jon: You just know that Palace, who have given up last few games since gaining PL safety, will be awesome today because it's United.
Wayne Rooney is playing as a lone striker for United in a 4-1-4-1 formation. Daley Blind is playing just in front of the defence.
Both sets of fans making a right noise.
Image source, .Only once before have Man United lost four consecutive top flight matches without scoring. That was from March to April 1909 against Blackburn Rovers, Aston Villa, The Wednesday and Bristol City. Surely not?
United have started well. Ashley Young is getting jeered with every touch of the ball - perhaps due to his Watford connections?
Yannick Bolasie almost races clear on goal with the hosts' first attack but he is comfortably offside.

"It's another fantastic game but they are two teams not in great form. Manchester United are desperate to get a win to cement their place in the top four of the Premier League.
"Crystal Palace are safe and will be playing in the Premier League next season, but will want to end their season on a high."

Great stuff from the former Newcastle manager.
