Kiko Femenia and Troy Deeney are off.

Tom Cleverley and Adam Masina are on.

Well, judging by the last 20 minutes, Chelsea have nothing to worry about. Watford can't get out of their half!

Nigel Pearson is making some more changes. He needs to!

Prof Sam: Chelsea still lack the sting in midfield. Lots of players there but short of goal scorers.

Stu: I have a feeling that Watford are not out of this as Chelsea can lose their focus in matches

Chelsea are 2-0 up and cruising but they're still working hard. They press high up the pitch and win the ball back almost immediately.

Willian then flicks it to Cesar Azpilicueta on the left, he crosses it into Olivier Giroud, who can't quite direct his header goalwards.

Willian turns in the middle, shrugging off two defenders and slips it through to Olivier Giroud.

The angle is tight and a combination of Craig Dawson and Ben Foster blocks his shot at the near post.

Danny Welbeck replaces Etienne Capoue for Watford. Can he spark some energy?

Watford haven't turned up for the second half. Someone should let Nigel Pearson know.

Chelsea are allowed to walk it through the centre and in the end, overplay it with Olivier Giroud trying to backheel flick it to Ross Barkley on the edge of the box.

Lovely move from Chelsea!

Christian Pulisic and Mason Mount play a slick one-two on the left but Mount's low cross back in towards Pulisic is dealt with at the near post by Craig Dawson.

The corner is straight at Ben Foster.

Adedayo: Even at 2-0, one is not feeling Chelsea have wrapped it up. That's the effect a bad defence can have. More goals to be really sure.

Troy Deeney heads it on in the box as Ismaila Sarr tries to get on the end of it. Will Hughes picks it up and slides a cut-back to Deeney but it's slightly behind him.

His touch pokes the ball to a defender and it's hooked clear.

Will Hughes has been busy for Watford. He tries to get an attack going on the left, linking up with a few players in midfield before one of them gives it away.

He turns around flapping his arms in frustration.

Adrian Mariappa gives away a free-kick on the left, catching Christian Pulisic a little late.

N'Golo Kante then plays a one-two with the ref (Kevin Friend waves play on), and it's switched over to Willian on the far side.

Christian Pulisic slips it left to Cesar Azpilicueta, who just about keeps his balance when he crosses it into the middle.

It's half-cleared to Mason Mount, who volleys it back towards goal but it's blocked. The rebound bounces off his shin.

Christian Pulisic is in great form isn't he? He cuts inside onto his right foot and tries to curl one in the top corner.

Gets too much on it.

Back under way.

One of the cleaners has just popped upstairs and I don't think he's realised I'm here. He's singing away. Hope he stops before the second half kicks off!

The players are back in the tunnel and ready to go again.

Adewusi Adewale: Pulisic is a pure gem, a very talented player that will take the league by storm next season barring injury, he reminds me of Eden first season as a Chelsea player.

Here's how the table looks with Chelsea currently in the lead. Back up to fourth. Any comeback from Watford?

They haven't caused any problems yet.

I'm back in the office tonight and it's absolutely dead. Got no friends. Wish I'd brought more biscuits with me.

He's also scored his 37th Premier League goal, moving him joint-third alongside Gabriel Jesus in the leading Brazilian PL goalscorers.

Only Roberto Firmino (56) and Philippe Coutinho (41) have netted more.
