An hour gone and Watford are showing plenty of intent. They've had 10 shots to United's three.

Gerard Deulofeu is continuing to be a menace.

Watford piling on the pressure. Troy Deeney battles to win the ball on the edge of the United area and it falls to Will Hughes, whose curling effort is just wide. That was close.

More deep conversations on the United bench. Concerning for United.

'Ole's at the wheel' is winging its way around Old Trafford once more as Daryl Janmaat is replaced by Kiko Femenía. He doesn't look too happy about it.

Watford have had five shots on target so far, so you cannot accuse them of sitting back.

A jinking run by Gerard Deulofeu ends up with the ball finding its way back to Etienne Capoue, who fires well over from about 35 yards.

More Watford pressure leads to another chance. This time it's Roberto Pereyra, whose low effort is well saved by David de Gea. The start of the second half is very similar to the first.

Can Watford make their chances tell this time?

Good possession from Watford as they go in search of an equaliser. They have never won a league game at Old Trafford but a point would equal their best return, previously set in 1985 and 1984.

Daryl Janmaat has a chance here from the edge of the box, but his shot is fired over.

Watford winger Gerard Deulofeu has another shot but it lacks any power.

United, though, go down to the other end and earn a corner which comes to nothing.

Watford get the second half under way.

Iain Moss: Mata has been absolutely central to Manchester United turning this game round. Martial & Matic have been passengers. Martial's reading of the game is awful!!

Richard Browne: This United team plays like Leicester’s PL winning side. Comprehensively outplayed but winning.

Comprehensively?

For 25 minutes, Watford were outstanding. That energy, pressing and creating chances - if you don't score goals, that will fade away later on.

Ashley Young uses his nous to win a free-kick wide on the right. Looked a bit tame, to be honest.

What can United muster from this? Juan Mata fires it in, but it's cleared.

That's the half.

Gerard Deulofeu bursts into the United area, but is crowded out. That allows United to counter again, and the Watford midfield are strolling back.

Luckily for them, Etienne Capoue bucks the trend and makes a timely interception.

Stan Stevens: Has anyone noticed Pogba's been sloppy since he changed his hair from black to shaved gold?

Into stoppage time and we'll have an extra three minutes.

Troy Deeney continues his battle with United's centre-backs and this time wins a free-kick.

Gerard Deulofeu whips it in from the left and Chris Smalling makes a great header to clear.

Watford corner, which doesn't make it past the first man. Disappointing from a Watford point of view.

Marcus Rashford wastes two chances to double United's lead. In the first, he drags Ben Foster way out of goal to the right but cannot find a team-mate with the goal gaping.

In the second, he jinks into the area, shapes to shoot but then passes straight to a Watford defender.

I don't get it when striker doesn't shoot. It's a dying trend.

Paul Pogba is growing in influence now as he slips a pass outside to Ashley Young, but his low cross is cleared.

Up the other end, Troy Deeney is enjoying a tussle with Phil Jones, who blocks a Daryl Janmaat shot.

The ball to Marcus Rashford is sublime, he draws Ben Foster out and then does a little flick over Foster for a wonderful goal.

This is a quality pass from Luke Shaw. Deft touch from Rashford. Brilliant from Manchester United.
