Willian's cross towards Antonio Rudiger inside the six yard box is blocked by a flying Adrian Mariappa header.

Almost a howler from Ben Foster.

Willian sets himself and curls a tame shot towards the bottom corner, Foster gets a hand on it but lets it squirm under his body, but to his relief it rolls wide of the post.

Two minutes remaining.

Chelsea look like they are taking home all three points.

Callum Hudson-Odoi has not had that much impact on the game, and however painful it is for the young lad, the manager has to do what is right for the team.

They need more defensive balance on the left hand side and Emerson will give them that.

How close was this!

A corner breaks loose to the edge of the box for Jorginho, but the Italy international blazes his shot just over the crossbar.

Watford 1-2 Chelsea

The sub is being subbed.

Callum Hudson-Odoi, who came on in the first half, is being replaced for the final five minutes by Emerson Palmieri.

And a final sub for Watford.

Gerard Deulofeu trots off and on comes Isaac Success.

Will that change prove to be...a success?

Soz.

A change for Chelsea.

Mateo Kovacic makes way for Ross Barkley.

Now at the other end, Watford skipper Troy Deeney has his first real sniff of goal, but flicks his shot wide at the near post.

What a run from N'Golo Kante.

The Frenchman picks it up on the edge of his own box, slips a pass to Eden Hazard before getting it back through on goal.

This can seal all three points for Chelsea, but Kante... can't finish, dragging a shot wide.

With all of the games that have happened this week, you just know this game is not finished. Watford are going to have chances

Steve: For all Chelsea's possession we miss a striker to rough up the defenders. How much do we need a Drogba or Costa?!

Pista: Atkinson is worse than an Xmas cracker joke isn't he?

Jon: Hornets fans are wrongly calling the ref biased. Was spot on both pen decisions

No, not on this occasion.

Jose Holebas's free-kick towards the near post is headed away by Mateo Kovacic.

Right, Watford have a free-kick in a good position down the left, can they make it count?

Chelsea have lost just one of their last 38 Premier League games in which Eden Hazard has scored in...

...a 4-1 defeat against Watford in February.

Willian could have put the game to bed.

The Brazilian receives a pass from Eden Hazard inside the box and drills a low shot which clips the far post.

Chelsea could have crumbled after conceding that late goal at the end of the first half, but you have to applaud them for how they have come out at the start of the second half.

Been a bit scruffy since that second Chelsea goal.

Has it knocked the stuffing out of Watford?

Here comes a Watford change.

Ken Sema is replaced by Domingos Quina with just over 25 minutes left.
