Wayne Rooney has been sent out early for a fitness test. He is trying to prove he can continue but there is still a limp going on there...
Just next to him on the pitch, Radamel Falcao is warming up intently.
Fair to say most of the play has been in the middle third? Judging by the average positions of each player, I think so.
It hasn't been a cracker.
It isn't looking good for Liverpool.
As things stand, Manchester United will move seven points clear of the Reds in that final Champions League qualifying place.
United will still have eyes on finishing in the top three and avoiding the play-off to get into the group stages.
Dan Church: What is going on with Luke Shaw ? Can't buy 90 minutes without an injury. Poor bloke
Stoogenuge: Luke "Hargreaves" Shaw.
Jamie McKellar: Dunno who's just come on but he's a spitting image of Jonny Evans.

"Crystal Palace finished the half strongly but if they concede another goal the game will be over. With the league position they are in they can just relax so they should just go for it.
"Luke Shaw going off has disrupted Manchester United, but United have been the better side, created the better openings and showed their quality. Palace have played as if they have got their brakes on."
Crystal Palace will be slightly aggrieved at being behind due to the manner of United's opener.
Scott Dann would argue the handball wasn't intentional that led to Juan Mata's penalty but, the visitors have done more than enough to deserve the lead.
Wayne Rooney's race might be run.
The striker goes down again after an awkward landing and needs treatment. He will get through to half time but will we see him again after the break?
Yannick Bolasie's low cross from the right finds Glenn Murray, but his shot on the turn is well blocked by United's Chris Smalling. The last few minutes have been a bit more encouraging for the hosts.
Palace enjoy some late, late pressure but without really creating anything. Four minutes of injury time signalled.
United again go close.
Antonio Valencia beats Wilfried Zaha on the right, pulls the ball back to Ander Herrera, whose cross misses Marouane Fellaini's head and bounces off Wayne Rooney to Julian Speroni.
Wayne Rooney is at least running a little easier. He almost gets on the end of Ashley Young's left-wing cross but the ball is scrambled clear.
Luke Shaw has had an injury nightmare ever since signing for Manchester United this season.
It looks the damage was done this time on his landing - perhaps to his neck.
Another injury worry for Manchester United as the stretcher comes on for Luke Shaw. He is sitting up but the medical staff look very concerned.
The defender took a rogue elbow to the nose from Glenn Murray and doesn't look great.
Shaw is stretchered off and replaced by Jonny Evans.
Wayne Rooney still doesn't look comfortable. He is limping around and surely won't last much longer? He is now rubbing his thigh.
Crystal Palace have to get a grip of this. They can't get hold of the ball at the moment.
Having said that, a neat period of possession sends Joel Ward down the right but he tumbles under the challenge of Marouane Fellaini inside the penalty area and play is waved on.

"Alan Pardew has to push Wilfried Zaha and Yannick Bolasie on and stop the ball coming out of Manchester United's defence.
"The problem for Palace is when they get the ball they are so deep it takes four or five passes to get near the United goal and by that time they have got back."
Free-kick to Crystal Palace on the halfway line but Joel Ward punts it forward and goalkeeper David de Gea collects.
Wayne Rooney is limping and substitute Radamel Falcao is warming up.
Carl Taylor: If that's at the other end of the pitch it's not a penalty, simple as.
Andrew Morris: Pen all day long. Dann deliberately moved his arm toward the ball and it hit his arm. Solution? Don't move arm towards the ball!
Dee Evans: A referee call that Sir Alex would be proud of!
Crystal Palace's heat map above shows the Eagles have spent most of their time defending.
They almost get in though at the other end as a free-kick into the penalty area is headed down by Scott Dann but an unmarked Glenn Murray is just unable to put the brakes on in time to reach it.
Louis van Gaal will have breathed a sigh or relief when Juan Mata converted that penalty.
The Reds had failed to score their last two spot kicks..
