Watford can have few complaints.

The hosts have had a disallowed goal and a decent penalty shout before Javier Hernandez's seventh Premier League goal of the season.

Former Everton midfielder on Final Score

Michail Antonio has had three or four great runs down the right and he's got crosses in, but no-ones been there for him. That time Javier Hernandez has latched onto it, and it's a very tidy finish.

This isn't a boring 0-0.

Etienne Capoue almost embarrasses Adrian from 25 yards but the West Ham keeper recovers after spilling the shot.

West Ham have the ball in the back of the net...but it's ruled out for offside.

It's a close call as Javier Hernandez powers Joao Mario's free-kick home.

A chorus of jeers break out from the home ends.

I think we're going to be seeing that again on Match of the Day later.

After those early chances and penalty shout, this game has lost some of its fizz.

The Hammers look the more likely to score but this has descended into a typical mid-table tussle littered with niggly fouls.

Ex-Chelsea keeper on Final Score

You've got to give credit to Watford for beating Chelsea - Watford did well. And when it was 1-1 Chelsea were very much in the game, but again to Watford's credit, they came again and scored the extra goals.

I think it would have been a different story had Chelsea had 11 players on the field, but nonetheless, it's a very good win from Watford and they'll look to build on that today against West Ham.

Watford have scored just three times in the past seven away games. How costly will that missed chance by Adrian Mariappa prove?

Both sides should have scored but it remains goalless at the 20 minute mark.

Very little to choose between the two sides.

This is bubbling nicely and West Ham are enjoying a decent spell of possession.

Orestis Karnezis saves from Joao Mario as Watford's defence struggles to clear.

West Ham want a penalty as Adrian Mariappa clatters into Marko Arnautovic but referee Graham Scott, who is in a great position, is not interested.

Arnautovic glided past a couple of yellow shirts as if they weren't there before Mariappa catches his ankle.

First decent effort comes from Adrian Mariappa who flings himself at a cross after a short corner. Adrian is equal to it but that's a warning sign for West Ham.

Decent from Marko Arnautovic who has made a bright start on his return to the West Ham side after a hamstring injury.

He whips in a decent cross which gives Hornets keeper Orestis Karnezis his first test.

Untidy start. West Ham have lost possession a number of times in the opening exchanges while Watford have yet to get going.

One positive for the hosts in the shape of Pablo Zabaleta who has made a couple of decent challenges.

Off we go...

"I'm Forever Blowing Bubbles" booms out of the speakers at the London Stadium.

Here come the teams...

Watford

Will Watford send another team from the capital packing?

The Hornets scored three times in the last six minutes to hammer 10-man Chelsea 4-1 on Monday.

"I know how we got those points - running a lot, and working a lot - and I think this is the key to the future," said Watford's head coach Javi Gracia.

"The last match gave us motivation, more credibility. We believe more in our work, and it is better for us but we know if we don't work and don't run we will not win."

West Ham United

David Sullivan hopes David Moyes stays as West Ham manager for "many years".

Moyes has only been in charge since November but speculation has started to mount as to whether or not Moyes will stay on at London Stadium.

The Hammers are still not safe from the drop - they are three points above the bottom three - but Sullivan is backing his manager, saying: "What I like is, he is very hard-working. You see him at grounds watching games. He puts a long shift in at the training ground. The harder you work, the better the results.

"He's a good manager and will prove it. I hope he stays with us for many, many years and achieves things and wins things."

A glance at the league table may suggest that this is a mid-table game - 11th against 12th - but the reality is that there is no mid-table: the scramble to stay up is consuming more than half of the top-flight's managers.

Watford's win over Chelsea on Monday night has given them some breathing space, and Javi Gracia - the 11th manager in the six years of the Pozzo family's ownership - an early landmark result.

The reverse fixture back in November was David Moyes' first game as West Ham manager. Back then, Watford were eighth and warding off Everton's interest in Marco Silva, whilst West Ham were 18th.

How quickly things change.
