Alvaro Morata involved again, he goes tumbling down in the box after attention from United defender Chris Smalling, but referee Anthony Taylor waves play on.

Morata is not happy, unleashing a few verbals at the man in black.

N'Golo Kante is back at the heart of Chelsea's midfield and the man with two successive title winners' medals here and at Leicester City is already showing what an influence he can be.

Referee Anthony Taylor is at least bringing Antonio Conte and Jose Mourinho closer together - they are both unhappy with a lot of his decisions.

Chelsea striker Alvaro Morata turns Chris Smalling inside and out like a wet towel, but then dribbles a shot from 10 yards straight at David de Gea.

The balance seems to be good in this Chelsea side today. Bakayoko and Fabregas have been let off the leash with Kante back and Herrera has got a massive job on his hands to keep control in that area.

Great enterprise by Ashley Young to win a corner, but taker Marcus Rashford fails to clear the first man.

Criminal.

Big opportunities already have been wasted with Rashford's miss at the other end. It's been a fabulous start to the game.

We had a frantic opening 25 minutes, but it has settled down a little bit now and Chelsea are starting to monopolise possession.

Everton break and Tom Davies tries to chip from distance over keeper Heurelho Gomes. He tried for the spectacular from about 30 yards out but it didn't work.

Now Watford have a chance! Kiko Fermenia curls the ball into the box but Andre Gray messes up from close range.

Eased out.

Alvaro Morata looks to get his head on the end of Cesc Fabregas's chipped pass forward, but the Spain striker is nudged off the ball in the six yard box by Eric Bailly.

Intelligent defending.

Watford now break forward through Abdoulaye Doucoure but the move comes a halt when Richarlison is flagged offside.

It's getting a bit more lively now.

Tiemoue Bakayoko with a trip on Ander Herrera in the opposition penalty area.

The Frenchman has started this game like a man possessed, he is everywhere.

Remember, he is on a booking so will not be given too many more chances by referee Anthony Taylor.

First real chance of the game for the hosts.

Full-back Leighton Baines calls Heurelho Gomes into action for the first time with a smart save.

Toffees front men Wayne Rooney and Oumar Niasse were both involved in the build-up to that move.

The intensity and determination is of the highest standard. Both teams here know that they need to win. The referee has to manage this game effectively because it's being played at such speed that there are going to be mistimed tackles. He can't be giving bookings for every foul.

Kiko Femenia makes an inviting run up the right but can't keep the ball in play, and the Watford full-back tumbles down the side of the pitch and into the adverstising hoardings.

It's fairly even so far and there's been no real chances on goal in 20 minutes.

Blue is the colour of his hair, yellow is the colour of the card he receives.

Tiemoue Bakayoko miscontrols the ball and then goes in late on Phil Jones, studs showing.

Booked.

That was some strike from Eden Hazard and de Gea pulled off an outstanding save with Morata just in front of him. A great chance for Fabregas on the rebound. He has half the goal to aim at but can't find the target. Could be 2-2 at the moment.

Having had to do a bit of defending at the back, Chelsea make their way up field and force another corner.

Eden Hazard cuts in from the right and rockets a left-footed shot which is arrowing towards the top corner, bit David de Gea watches it all the way to push it away.

On the follow up, Cesc Fabregas heads into the sidenetting.

Half the ground thought that was in.

Chance after chance, what happened to those buses??

Lively stuff in the first 15 minutes and Chelsea manager Antonio Conte spun around waving his arms in fury when Tiemoue Bakayoko missed that glorious opening.

The Italian is prowling his technical area constantly while his Manchester United counterpart Jose Mourinho is just making the occasional appearance.

Romelu Lukaku's first sniff at goal against his old club.

He spins past Andreas Christensen 22 yards out, but his low, curled shot towards the far post is pushed away by fellow Belgian Thibaut Courtois.

A less subdued start over at Goodison Park. Rather scrappy.

Watford earn the first corner which is wasted.
