United punt long towards Marcus Rashford, but Fernando Fernandez muscles him out of it.

The hosts have won a free-kick though when the Swansea defender catches Anthony Martial by the corner of the penalty area.

Good spot for a delivery...

Ricky Lee Everett: Do or die now for United and the hunt for top four. Problem is, can they just turn a switch and turn this around? 

Viv: Fantastic free-kick from Sigurdsson, well placed and well executed! Herrera called it right but De Gea couldn't do anything about it! 

Ryan Buckley: This really is the theatre of draws isn't it? 

Herrera was initially stationed on the post that Sigurdsson scored inside of. De Gea, concerned about allowing Fernando Llorente to stand close in by moving the offside line to his goalline, waved him away before the free-kick was taken though.

Swansea are still putting everything into trying to win this game - they just have to make sure they don't concede down the other end.

Swansea are still sniffing around though.

Tom Carroll clears the bar by a yard as he pulls the trigger from just outside the box.

It is an open game. Five to go.

Was that the chance?

Jesse Lingard heads straight into Lukasz Fabianski's gloves when picked out at the far post.

Anything downward and either side of the Swansea goalkeeper was probably scoring.

Garrypl: I can't even process what was going on with Herrera there. He had the right idea, but De Gea told him to go back. 

Thomashollern: Herrera doing the hokey cokey 

Ashley Tezoo: Glyfi. Sigurdsson. Postage. Stamp. 

Anthony Martial smashes a shot clear over the top from distance.

There is an urgency about United now. But they have to make sure that doesn't stray into desperation.

I think there will be at least one more chance for them in this if they keep their heads...

As it stands, Manchester United are fifth, behind Manchester City on goal difference and Liverpool by a point.

Swansea are two points off 17th-placed Hull.

I tell you what, he's put that on a postage stamp. Top corner from Gylfi Sigurdsson. 

What a lifeline for Swansea.

Absolutely sublime.

Gylfi Sigurdsson sends a free-kick arcing into the corner. David de Gea didn't even dive.

It wouldn't have mattered if he had. It was perfectly placed.

This scoreline might not be enough for either side though. This could be a roller-coater conclusion.

Wayne Rooney brings down Martin Olsson just outside the D of the Manchester United box.

This is prime Gylfi Sigurdsson territory...

I still think Wayne Rooney has so much to give Manchester United. These young players can learn so much from him. They give him the ball and he sees the passes which they can't see. His touch has been superb. 

Efforts at both ends.

Antonio Valencia wallops a shot in from a tight angle that Lukasz Fabianski is equal to in the Swansea goal.

Swansea counter and Gylfi Sigurdsson clears the bar with a rushed shot from the edge of the box.

Still life in this contest.

Fifteen to go.

United are going up to third as it stands remember.

They have not been as high since the fourth game of the season.

Swansea are three points from safety if it remains the same to full time.

What an entrance.

Substitute Martin Olsson makes his first impression in the game as he chases a loose ball and comes clattering into Ashley Young, sending the United full-back spinning high in the air.

Both men are up after a bit of wincing...

Martin Olsson is going to replace the unlucky Jefferson Montero.

When things go against you they really go against you. Did Jefferson Montero just not warm up properly?

With 20 minutes left, what can you do now? Paul Clement is racking his brains.

Jefferson Montero has added a bit of nitro boost to the Swansea team.

He wins a corner as he darts down the left for his team.

Too fast for his own good though...

The Swansea substitute - who has only been on the pitch for five minutes - looks to have twanged his hamstring.

There is going to have to be a change.

Colin Reardon: Bailly injury self-imposed! He goes in for ridiculous, unnecessary challenges! Naive!

Jason Moore: Mourinho's refusal to introduce youth to the first team may cost him. Been a few games Bailly could have been rested for. 

Sophie Gayter: If this continues it really will be Mourinho and Tuanzebe against Celta Vigo...
