Watford are shell shocked.
Antonio Conte's substitutions have changed the game.
As I type that Michy Batshuayi rattles the bar.

Michy Batshuayi is making an absolute nuisance of himself, he gets into the box and crosses for Branislav Ivanovic, but Heurlho Gomes is brave and saves at the feet of the Serbian.
Watford struggling to hold on here.
The Belgium scores his first Premier League goal since a £33m arrival from Marseille in the summer.

Cesc Fabrega is on for Nemanja Matic.
It's his first Premier League appearances this season, can he make a point to Antonio Conte?
He has made all three substitutions now, dice have been rolled.
Still just the one shot on target for Chelsea in the whole match, that's despite 60 per cent possesion.

Watford putting the pressure on now, they are going for a second.
N'Golo Kante fouls Troy Deeney and gives a free-kick to Watford.
Jose Holebas takes it but smacks it into the wall. Ball is held up in the box by Odion Ighalo and there are shouts of a handball but nothing in it.
Has that goal sparked Chelsea into life?
Eden Hazard has a low shot saved and then Nemanja Matic shoots wide.
Diego Costa was shown a yellow card for dissent in the aftermath of that goal.
Two in two for Etienne Capoue.
Adlene Guedioura's cross finds the Frenchman in the box, who is in acres of space, the Chelsea defenders are sleeping as he controls with his chest and rifles it into the top left corner.

Oscar's early ball finds an arriving Eden Hazard in the box and he tries to go with the first-time effort on his left foot but blasts wide.
Hazard of 2014/15 would have buried that.
Bit more press from Chelsea this half. Wonder what Antonio Conte's team talk was like?Copyright: Getty Images
