Swansea 0-1 Man Utd

It's a great time to score, but an awful, awful time to concede.
Swansea will be gutted having contended with United for 99% of the half.
Swansea 0-1 Man Utd
And the goal is just about the last action of the first half.
Eric Bailly
On the stroke of half time, United take the lead.
Paul Pogba thinks he has broken the deadlock, smashing a header towards goal which Lukasz Fabianski brilliantly tips onto the bar.
It drops down, but has it crossed the line?
No.
Eric Bailly reacts quickest and sticks a long leg out to push it into the net to put United ahead.
Harsh on Swansea, who have played quite well in this contest.
Swansea 0-0 Man Utd
Ooh, nearly an opening for United as Paul Pogba chips a delightful ball to the back post.
Romelu Lukaku is readying himself to thump a header into the net, but Federico Fernandez grows just enough to head the ball away.
Corner...
Swansea 0-0 Man Utd
Manchester United had a walk in the park against West Ham last week, they are in much more of a fight against Swansea.
Swans goalkeeper Lukasz Fabianski darts off his line to the edge of the box and makes a mess of the catch, dropping it to Juan Mata eight yards out, but the Spaniard clips his effort wide of goal.
Swansea 0-0 Man Utd
Swansea's Roque Mesa, clean shaven but a little moustache sitting on his top lip.
Old school.

Michael Reid: Anthony Martial would have finished that...
Omoba1: Why does Rashford start ahead of Martial?
Sho Rahman: And that is why I prefer Martial over Rashford.......
Swansea 0-0 Man Utd
Swansea get a free-kick which Roque Mesa curls in beautifully.
Again, Kyle Bartley is the man on the end of it, but elects to head across, instead of at, goal and the chance ebbs away.
Swansea 0-0 Man Utd

Marcus Rashford has been getting some rough treatment from Swansea's players, and he's not too popular with the Swans' fans either.
The forward was accused of diving to win a penalty during United's draw against Swansea at Old Trafford last season, and it doesn't sound like the home fans at the Liberty Stadium to have forgiven him.
Swansea 0-0 Man Utd
This is poor from Marcus Rashford, he really needs to work on his finishing.
The Manchester United man is on to Alfie Mawson's wayward header in a flash and in one-on-one with Lukasz Fabianski, but tamely hits his strike straight at the goalkeeper.
He missed a sitter in the Super Cup against Real Madrid and this is another chance he should have put away.

James Simpson: Reckon we'll bring Pogba off soon in case he gets another yellow card
Seth Gogo Egoeh: Mourinho better sub Pogba before he gets a red card.He is currently losing his head. Herrera?
Richard: If he let Fer off with identical tackle to what Pogba was booked for, seems fair to show leniancy.
Swansea 0-0 Man Utd
It is Kyle Bartley who gets on the end of the corner, but glances his header wide of goal.
An extremely entertaining contest, despite the lack of goals.
Swansea 0-0 Man Utd
Brilliant play from Swansea.
Tammy Abraham and Jordan Ayew working very well together, as the on loan Chelsea man sets his partner free down the right.
Ayew outpaces Phil Jones and crosses a low ball into the box, which a United player is able to clear.
Corner for Swansea...
Swansea 0-0 Man Utd
Just a taster of what Marcus Rashford has been complaining about...
Swansea 0-0 Man Utd

Are Manchester United getting a little frustrated? Paul Pogba's yellow card for a foul on Tom Carroll might suggest so.
The French midfielder has been moaning at referee Jon Moss, who has had to have another quiet word with him after bringing down Martin Olsson.
Pogba will have to be careful from here on in.
#bbcfootball
Biafran God: Pogba tackle more malicious and deadly yet all he gets is a yellow card while Cahill for less got a red.
Johnny Magrinho: Rashford needs to stop being so petulant. Any decision that goes against him he's throwing his arms around like a child. Poor.
Jerry Elumeze: Pogba's tackle deserved a yellow card but so did Fer's. Why give one and not the other?
Swansea 0-0 Man Utd
Final, final warning for Paul Pogba.
Having been booked just a few minutes before, the Frenchman flies in on Martin Olsson, tripping the Swansea man.
It is a foul and if he had not already been on a yellow, he would surely have got one.
Ref Jon Moss calls him over and does not brandish a red card, much to the anger of the home supporters.
Swansea 0-0 Man Utd
Paul Pogba is in trouble here...
Swansea 0-0 Man Utd
Marcus Rashford's low, long range strike skips off the turf and straight into the hands of Lukasz Fabianski.
I make that the Swansea goalkeeper's first save.
