There is still time, but at the moment, Leeds are going down to a first league defeat of the calendar year.

The home fans try and give their side a bit of encouragement.
Leeds haven't been great tonight but the Hornets have worked incredibly hard.
This would be two wins in two for interim gaffer Tom Cleverley.
The 34-year-old grew up in Bradford and played for Manchester United so you'd imagine he'd really relish getting this over the line.

Leeds cannot seem to break through this stubborn Watford shape and system.
It has been a great team performance from the Hornets, will players playing better than they have for the majority of the season.
If anyone is going to spark the visitors into life, it will be Crysencio Summerville, his ability is top notch.
SUBSTITUTION
Watford 2-1 Leeds
Leeds go their bench for the second time.
Forward Joel Piroe comes on for Georginio Rutter, who had an operation on a hernia in the international break and has been on the periphery of things tonight.
The Whites have under 20 minutes to avoid a first league defeat since 29 December.

Derek Payne
Former Watford midfielder on BBC Three Counties Radio
Watford's high press has definitely gone, especially now that Emmanuel Dennis is off.
But Leeds haven't really created a lot, it is all in front of Watford.
The game is definitely cagey. Watford know that the onus is on Leeds.
They are not panicking at the moment.

Leeds are probing away as they look for an opening.
Watford are having to get through a lot of work out of possession.
They've already made one sub and I think they might need to get some more fresh legs on soon.
'Leeds need to run at Watford's defence'

Jon Newsome
Former Leeds and Sheff Wed defender on BBC Radio Leeds
It has taken Leeds 20 minutes to open up and get together a passage of play that has looked anything like threatening in this second half.
They need to get the overload on one side whereby Dan James or Crysencio Summerville are running at a centre-half.
We saw when that happened in the first half that they took Watford defenders to the cleaners.

Dan James has a dip for Leeds that goes through a few bodies but Daniel Bachmann keeps his eye on it and makes a comfortable enough save.

It looks like Junior Firpo coming on will mean Ethan Ampadu will go to centre-back and Archie Gray goes into the middle of the park.
SUBSTITUTION
Watford 2-1 Leeds
Leeds go to their bench.
Liam Cooper is off and Junior Firpo is on and that will mean a rejig.
Cooper was making his first league start since 1 January and had a pretty tough night.
Post update
Watford 2-1 Leeds
Leeds have pretty much dominated possession this half, unsurprisingly.
A point wouldn't be enough for them to go back to the top of the table but would move them one clear of Leicester, who lost at Bristol City at the start of this very long day of EFL action.
Long way to go in this yet and Leeds boss Daniel Farke will be confident his side can get back into it.

Emmanuel Dennis went down straight away. I think he knew (that he was injured).
He had come back after not playing competitive football for months.
That is always a concern. But you can't risk anything with him.
I think Tom Cleverley would have made a substitution anyway.

His impressive goal has them in front but Emmanuel Dennis' race is run for Watford tonight.
The Nottingham Forest loanee, who has had a real stop-start season including a goalless loan spell in Turkey with Istanbul Basaksehir, looks to have pulled a muscle.
Ismael Kone is on in his stead.
'Watford looking tired'

I think Watford will make a change soon as tiredness is setting in.
Their manager Tom Cleverley would have known that this would happen.
He will bring some energy in.

Leeds are starting to put their foot down now.
They move the ball around well and Georginio Rutter eventually gets a shot off that is deflected behind for another corner.

Watford 2-1 Leeds
Leeds win a free-kick after overplaying on the initial corner from the Crysencio Summerville shot.
Sam Byram looks to convert after a better worked routine on this set-piece but the flag is up as Watford hack it off the line.
It's a moot point, but not quite sure it should have been offside actually. No VAR in the Championship of course.

Sam Byram had a little cut inside and played the ball into Crysencio Summerville.
It has got to go into the back of the net, really, otherwise what was wrong with the cut back?

It's the seventh time they've let in two or more goals in a Championship game all season.
