Chelsea picked up their fifth successive Premier League win after seeing off Watford 2-1 at Vicarage Road on Saturday evening.
Tammy Abraham returned up top as did Kepa Arrizabalaga in goal for the Blues following their Carabao Cup exit to Manchester United in midweek.
Chelsea hit the front inside five minutes when Jorginho played Abraham in behind the defence to fire over the head of Ben Foster who failed to narrow the angle.
Foster kept the score down 13 minutes in with a diving save off Christian Pulisic’s near post effort following a far post delivery from Willian off a corner.
Craig Cathcart struggled to carry on playing after 20 minutes and passed over the captaincy to his successor Adrian Mariappa too.
Watford threatened a response five minutes before halftime when Gerard Deulofeu weaved through the defence before skimming wide of the left post.
The Blues finished the half the brighter though after Mason Mount cut inside to rattle the crossbar with a rocket of a shot on 43 minutes.
Chelsea started the second half just like the first ended when Mount brought the best out of Foster with a solid strike following a cross from Willian.
Abraham turned from goal-scorer to provider for Pulisic 55 minutes in as he drilled in a low ball into the six-yard area which the American-born slammed home.
The visitors found a big chance for a third 69 minutes gone, as Watford struggled to get a look in however Abraham saw his effort blocked away by Mariappa.
The Hornets set up a lively finish when the Video Assistant Referee overturned an off-field decision for a penalty ten minutes from time following a foul on Deulofeu, who converted the effort too.
Frank Lampard looked to ran out the result in the final three minutes, with the entry of Michy Batshuayi who replaced Abraham.
The Blues bagged all the points in the end despite the best efforts of Foster who threatened an equaliser from a free-kick right at the death.
