Kepa gets a strong hand to it right at the end.
He does not get enough credit. He does not make many mistakes and he’s having a good season.

Chelsea have another win...but that was a bit uncomfortable in the end.
Watford 1-2 Chelsea
Incredible.
Ben Foster gets on the end of the free-kick and his header is creeping in..but Kepa Arrizabalaga gets a hand to it to divert it away.
Drama...

Ben Foster is up for a late free-kick...

There was late, late drama at Villa Park.
Will we see any at Vicarage Road?
Chelsea make another change. On comes Reece James.

Sho: I'm watching what Lampard is doing at Chelsea and feeling that he's making a bit of a mockery of Solskjaer at the minute. If you consider that Chelsea haven't had Rudiger and Kante for most of the season it's so impressive what they're doing right now.
Agubata Odinaka: I wonder who Frank Lampard will sacrifice when Kante gets back. Would be absolutely an injustice to take Kovacic out. He has earned a stay of execution.

Five minutes of stoppage time!
Will Watford rescue a point?

Noel Fitzpatrick: That was never a penalty!!!! Deulofeu took two steps after the challenge, and when he knew the ball was gone, he went down. He should have been booked for diving! Awful decision!!
Adam: We all know that wasn't a penalty right?

Jorginho and Gerard Deulofeu tangle and words are exchanged. Jorginho is clearly rattled after conceding the penalty that has given Watford hope. Will Hughes steps in as peacemaker.
Watford 1-2 Chelsea
Chelsea should have the points in the bag after a dominant performance.
Instead they are having to endure a nervy ending.
For all their exciting, attacking play this season, they've managed just two clean sheets in the Premier League.

Chelsea's first change. Hello Callum Hudson-Odoi. Goodbye Christian Pulisic.

Deulofeu was definitely fouled in the box. It is a good call, well done VAR for being brave to change the referee’s initial decision.
Watford 1-2 Chelsea
That's going to hurt.
Craig Dawson goes in HARD on Emerson.
That's a booking all day long.
Watford 1-2 Chelsea
Chelsea are not happy one bit. They feel that was a soft penalty and Frank Lampard is venting.
Gerard Deulofeu
Gerard Deulofeu picks himself up, dusts himself down, and sends Kepa Arrizabalaga the wrong way. Game on.
Watford 0-2 Chelsea
Given!

Gerard Deulofeu goes down after a challenge by Jorginho.
VAR is taking ages to decide whether it's a penalty.
