The final corner of the game is swung in and despite a congested box, De Gea manages to knock it clear to the left as he falls back into his own box.
90' +4
Save from De Gea! The booming free-kick hoisted in is met by a cracking header from Kabasele and the Spain goalkeeper performs a brilliant move to push it out for a corner.
90' +3
N. Matić gets a second yellow card and is sent off.
Hughes looks to break down the right wing - and Matic carelessly barges into him to cut off his run. It's a second yellow for the United man - and therefore a red. The visitors will play out the final minute or so with 10 men.
90' +2
E. Bailly enters the game and replaces A. Valencia.
Eric Bailly replaces Valencia as United look to eat up the few remaining seconds.
90'
Doucoure lashes a rocket of a shot at De Gea that the keeper does well to smother at the near-left post. Three added minutes incoming.
88'
I. Success enters the game and replaces C. Cathcart.
Isaac Success meanwhile arrives as the final Watford change for Cathcart.
McTominay gives a little lift to United as Young puts him around Femenia with a slick move. The Watford defence quickly firm up but that move serves to unsettle their stride a little.
86'
There's the sense United are holding onto these three points with a rather tenuous grip at the moment. Watford look the sharper and more aggressive of the pair, if not clearly the smarter.
84'
S. McTominay enters the game and replaces A. Sánchez.
A. Masina enters the game and replaces J. Holebas.
...while United bring on Scott McTominay for Sanchez.
Another change for each side; Watford take off Holebas and introduce Adam Masina...
81'
A. Valencia gets yellow.
Valencia picks up a booking as the game enters the final 10 minutes for an intentional handball in open play.
80'
Martial has a resounding chance for United as the visitors break again - but the substitute, one-on-one in the box, can't escape the pursuit of Kabasele who lands a wonderful slide tackle to ferry the ball away.
Minute
Description
78'
It's a less-than-stellar set-piece and United punish Watford with their most sizzling counter-move for some time. Valencia and Lukaku combine through a break and square pass to lay the ball on a plate for Sanchez; only a late Cathcart slide can deny the Chilean.
77'
Only seconds later, Smalling fouls Deeney 25 yards out on the left and concedes a free-kick. Holebas' effort is weak but does result in a corner for the hosts.
76'
Pereyra lays a pass back off the wing for Doucoure who tries a 25-yard effort that was never going to trouble De Gea, sailing out for a goal-kick.
74'
This is an excellent spell for Watford still, who are pressing United with far more intent than they have for most of the game. Pogba and Lukaku are unable to turn service out wide for Young and Valencia under the weight of the Hornets and it is telling on their game speed.
72'
Kiko Femenía enters the game and replaces D. Janmaat.
Watford follow suit, and bring on Kiko Femenia for Janmaat.
71'
A. Martial enters the game and replaces J. Lingard.
United now make their first change of the game, with Lingard replaced by Anthony Martial.
70'
N. Matić gets yellow.
Matic is shown a yellow card by referee Dean, but only after it had initially appeared to be branded at Deeney.
69'
Pereyra thinks he has a shout for a penalty after another brisk counter-attack ends with him sprawled in the United box from a Lindelof challenge but the referee waves his claims away.
67'
Deeney goes hunting a long ball from the restart which sees him challenge Fellaini in the air. The United man catches him with an elbow across the face and play is paused for him to get some treatment.
65'
A. Gray has scored a goal for Watford! Assist by A. Doucouré.
The build-up run from Watford, well-worked around the United defence, allowed Doucoure to create that smart run and deliver his cut-back. Good work from the hosts and Vicarage Road responds in full voice.
GRAY PULLS ONE BACK FOR WATFORD! 2-1! A strong spell for the Hornets pays off with a lovely finish from the striker, as he races into the box to meet Doucoure's shaped cut-back pass and thrash it into the top-right corner. United have held firm for so long today but now find themselves with a tenuous lead.
62'
This time, Holebas finds Matic who clears with some ease. Pereyra looks to bring it back in but Lingard fouls him, conceding the free-kick on halfway.
61'
Holebas' set-piece finds Smalling who heads away for a second corner.
60'
After a little confusion, Pogba and Young play short before the latter booms a cross wide to the right post. He only finds empty turf though and Watford counter briskly, winning themselves a corner down the other end through Gray.
58'
Pogba goes down under a challenge from Doucoure 30 yards out to the left of the Watford goal and United win the free-kick.
56'
It's Pereyra who will take the set-piece for Watford too - and his effort is poor, raising it well over the crossbar as he looks to try and dip it beyond the defensive wall.
55'
Watford now pick up a free-kick of their own in a promising position, 25 or so yards out on the left after Pereyra is barged to the ground by Valencia.
52'
Kabasele makes a needless challenge on Lukaku and concedes the free-kick just inside United's half.
50'
Pogba sprays a shot across the face of goal following a keen assist from Young, but Watford looked a little too rigid around the back there to respond to the threat in the first place.
48'
Hughes wins a free-kick off Young on the right wing for the Hornets but the following set-piece can't trouble De Gea and Holebas' follow-up a moment later sails well over the goal.
46'
We're back underway at Vicarage Road; can Watford muster a response and overturn their first-half deficit?
45' +2
HALF-TIME: WATFORD 0-2 MANCHESTER UNITED
45' +1
United win themselves a corner after Pogba sees a close-range shot steered wide by Foster, on the back of a sensational piece of build-up from Fellaini and Valencia who combine with a breathless beauty down the right wing.
45'
Two added minutes incoming.
42'
Hughes concedes a corner and United pop up in the box again; this time, they can't snaffle a third however and Watford clear through Holebas.
40'
Watford are in free-fall here. That one-two punch from the Red Devils has taken the wind out of their sails in brutal fashion.
38'
C. Smalling has scored a goal for Manchester United! Assist by M. Fellaini.
The assist is Fellaini's but Young's corner set that up wonderfully too. On the touchline, Jose Mourinho celebrates with the biggest smile seen on his face for some time. That was a dynamite goal.
SMALLING MAKES IT TWO IN THREE MINUTES! 2-0 TO UNITED! A finish from heaven at Vicarage Road as a Young corner is delivered to Fellaini who knocks down for his team-mate to turn in with a beautiful half-volley on a dime. Wonderful stuff.
37'
United almost snare a second as Pogba launches a rocket from the restart that Foster bobbles somewhat, taking it over near the post for a corner.
36'
J. Holebas gets yellow.
Holebas is convinced that Lukaku was offside as he nudged that ball in, accosting the referee who books him for dissent.
35'
R. Lukaku has scored a goal for Manchester United!
LUKAKU GIVES UNITED THE LEAD! 1-0! It all comes from the free-kick 40 yards out that Young floats out wide to Fellaini on the right of the box. The Belgian's square cross back into the box deflects out wide to the left where Young lashes it back in again towards the right post - and Lukaku pops up to bundle it in. The visitors have their noses in front.
34'
É. Capoue gets yellow.
Capoue brings down Lingard as the United man threatens to break free and referee Mike Dean books the Watford man for his cynical foul.
32'
Young's corner flies deep and wide this time, allowing Watford to create a counter-attack from which Gray earns a free-kick off Lindelof.
31'
Save from Foster! Sanchez, supplied by Lukaku, races into the right edge of the box and squeaks out a tightly-angled shot that the former United keeper tips over for a corner.
28'
Watford win a corner off the defending of Valencia and Holebas spikes it in with a wide, booming kick. It pings around players from both sides before Smalling eventually sticks it out for a throw-in further upfield.
26'
Pereyra fouls Valencia and United play themselves back into a good striking position but find themselves unable to chalk up an effort as the Watford defence boxes them off with sharper briskness than before.
24'
Young's set-piece is an excellent delivery that Foster misses and United are allowed to marshall a second attack. Sanchez finds the back of the net a moment later - but the linesman's flag is up and the goal does not stand.
23'
Valencia, Matic and Young combine to spread the ball wide from the right to left, seeking to slip around the Watford defence - and they earn a corner for their efforts.
19'
United try the overhead pass to pick out Lukaku in the box, who is deemed to be marginally offside by a whisker.
17'
Fellaini clears up the set-piece swung in a moment later and United clear their lines.
16'
Save from De Gea! Some slow defence around the United box allows Watford to set up a plum chance for Deeney, who rockets it towards the upper-right corner of the goal, forcing the Spaniard to tip it over with one hand.
14'
Capoue blocks a Pogba cross, taking it out for a throw-in on the left wing and then Cathcart earns his side a goal-kick as he shepherds the ball out of play near Young.
13'
At the opposite end of the field, Hughes creates some space for himself on a quick counter and squares a shot straight to De Gea after he comes under pressure from Smalling.
12'
Valencia harks down the right wing and pings it wide to Young on the left who frees up Pogba for a strike. It's a fairly weak effort by the Frenchman's standards but Foster is still forced to dive low to deal with it.
10'
Pulled out of shape by another Holebas counter, Watford don't react sharply enough to cut off Lingard, and are lucky that the England man can't control the ball as he approaches the box, ceding the ball to Foster instead.
8'
United look to have the greater sense of threat in these opening exchanges but Watford don't look unduly worried either. Holebas has broken wide a couple of times so far to show his threat with the ball.
6'
Sanchez and Lukaku combine on a breakaway counter down the centre of the field to threaten the Watford defence, but Young's finishing cross in from the left only goes to Foster.
4'
Down the other end, a long throw for Watford finds its way to Doucoure who lets loose with a 20-yard half-volley that sails well off target to the right of the far post.
2'
Lukaku almost snaffles an early opener for the visitors, meeting a floated cross but unable to control with his first touch, leaving a window for Foster to dive in and scoop up the ball away from danger.

We are underway in this Premier League tie between Watford and Manchester United!
Hello and welcome to live coverage of the 2018-19 Premier League as unbeaten Watford host Manchester United at Vicarage Road. The Hornets have won four from four under Javi Gracia with a rather remarkable start to the season; can they make it five against Jose Mourinho's Red Devils, whom they have only beaten once in their last 13 games?
With the international break concluded, it's back to business as usual in English football - and Watford will be looking to keep up with fellow pace-setters Liverpool and Chelsea if they can today. As for United, they will be looking to record back-to-back wins for the first time this campaign; will they find a key three points on the road?
Team news now and it's a Watford XI unchanged to the one that defeated Tottenham a fortnight ago. As for United, they make one switch, with Ashley Young replacing Luke Shaw following the former's head knock on England duty - though they are of course without Marcus Rashford due to suspension.
MANCHESTER UNITED (4-3-3): David De Gea; Antonio Valencia, Chris Smalling, Victor Lindelof, Ashley Young; Paul Pogba, Marouane Fellaini, Nemanja Matic; Romelu Lukaku, Jesse Lingard, Alexis Sanchez.
Subs: Adam Masina, Heurelho Gomes, Nathaniel Chalobah, Adrian Mariappa, Isaac Success, Kiko Femenia, Ken Sema.
WATFORD (4-4-2): Ben Foster; Christian Kabasele, Jose Holebas, Craig Cathcart, Daryl Janmaat; Etienne Capoue, Abdoulaye Doucoure, Roberto Pereyra, Will Hughes; Troy Deeney, Andre Gray.
Subs: Juan Mata, Fred, Matteo Darmian, Lee Grant, Eric Bailly, Anthony Martial, Scott McTominay.
The teams are out at Vicarage Road and we're moments away from kick-off.
Javi Gracia will have to give an impressive team-talk at the break - but will he make any changes to breathe new life into his side? The international break meanwhile has served Mourinho well; his United side have lost their jaded edge today, and look to be in rather rude health.
Watford's bubble looks set to burst at Vicarage Road as goals from Romelu Lukaku and Chris Smalling hand Manchester United the lead at the break. The Hornets have been boxed in by the Red Devils with impressive strength and, going forward, the visitors have been back to almost their imperious best. It will take a big swing in the wind for the Hornets to come back into this one; at half-time, it's Watford 0-2 Manchester United.
Andre Gray's lovely finish set up a finale on a knife-edge at Vicarage Road - but in the end, it is the hosts who go down in defeat to lose their perfect record this season. Jose Mourinho's side hang on after a more jagged second half to get the three points; at full-time, it finishes Watford 1-2 Manchester United.
For United, they return to Old Trafford with back-to-back wins under their belt next week as they meet Wolves but first meet Young Boys in the Champions League; Watford meanwhile make the short trip south to face Fulham. Until then, thank you - and have a good weekend!
