To be fair to Gerard Deulofeu, he has two wads of cotton wool up his nose to stem the blood flow. He's already had his tights ripped off (see earlier). Quite an afternoon for the Watford winger.

United knocking the passes around now. That goal has completely changed the mood and the game inside Old Trafford.

Phil Jones falls on top of Gerard Deulofeu after they battle for the ball and the Spaniard is getting treatment.

By the way, Marcus Rashford now has 10 Premier League goals, his best return in a top-flight season.

Anthony Martial wins a corner, and a short one finds its way to the Frenchman about 10 yards out, but he's denied by Ben Forster. Fine save.

Crying shame for Watford after dominating early proceedings. That was United's first shot on target.

Here comes Gerard Deulofeu again, but Phil Jones is across again to clear. The United defender been excellent so far.

'Ole's at the wheel' is being sung once more. United look more settled now.

Gerard Deulofeu is the latest Watford player to test David de Gea with a shot, but again it lacks any ferocity.

Watford are on top so far. That's five shots in all, now.

Anthony Martial is now appealing for a penalty after being touched by Miguel Britos. But that's all it was: a touch.

Anthony Martial is sprinting down the left now, but is blocked off by Adam Masina, who apepars to touch it back to Ben Foster. Martial leads the appeals for a back pass, but ref Stuart Attwell says no.

Strange.

Watford striker Troy Deeney is away down the right now with time and space to cross. Too much, from a United point of view. Phil Jones heads clear for a corner, but it comes to nothing.

Nice build-up by Watford, before Gerard Deulofeu finds Roberto Pereyra on the edge of the box, but his shot lacks pace and is easily saved by David de Gea. The United keeper looks fine after that early injury worry.

United starting to improve. Luke Shaw is inside the penalty area, close to the byline with time and space, Marcus Rashford is in the middle, but the left-back plays it straight to a Watford defender.

Good chance, that.

Will Hughes has a chance to shoot outside the box, but his shot is blocked. Now Marcus Rashford is away but Ben Foster is out to clear.

Hughes goes into the book for a foul on Paul Pogba in the build-up to that chance.

Fifteen minutes gone and Watford have had 63% possession. Not quite the party atmosphere inside Old Trafford.

Better possession from Man Utd as Nemanja Matic switches play from left to right, finding Ashley Young. But the right-back's cross is too high for the lurking attackers.

Few words from Ole Gunnar Solskjaer to Marcus Rashford about how United are playing.

Something needs to change as Watford are bossing it so far.

Ashley Young is now caught in possession on the edge of his box and the ball almost squirms through to Troy Deeney.

Moments later Daryl Janmaat then finds the Watford striker, but David de Gea scoops his header away and is injured in the process.

Concerning times for the hosts.

United relieve the pressure as Paul Pogba sets Marcus Rashford free on the counter. The striker wins a corner, which is fired towards Chris Smalling whose header lacks direction.

The hosts are struggling to get any passes together and even to get out of their own half.

This is not the type of start Ole Gunnar Solskjaer would have wanted at all. Concerned faces on the United bench. Troy Deeney fires wide and high from 25 yards.

Positive start by Watford, and this is a very presentable chance for Abdoulaye Doucoure, who has time to shoot from about 12 yards out, but skews his shot wide.

United are lacking fluency.

Gerard Deulofeu runs into the box and almost finds Troy Deeney, but Chris Smalling clears.

The Watford winger is then told to take his black tights off by the referee as they are not the same colour as Watford's green kit. Rather than take them off, someone is attacking them with scissors.

Bizarre!

Lovely sunshine now as 'Ole's at the wheel' rings around Old Trafford.

Good possession by Watford as the hosts struggle to link passes together.

Scrappy start.
