The second half is now under way.

No changes at half-time.

Cesc Fabregas remains on the Chelsea bench.

Branislav Ivanovic's (2) average position for the half is the same as Pedro's (11)

That is an attacking full-back.

The problem is Jose Holebas has been finding a lot of joy down that flank, maybe Ivanovic should drop back a tad.

Chelsea have almost two-thirds possession but for all their dominance they have had one shot on target.

Watford have had the best chance with Odion Ighalo putting over from six yards out on 24 minutes.

Jose Holebas and Adlene Guedioura are causing plenty of problems on the flanks.

One minute of injury-time.

Free-kick to Chelsea.

Eden Hazard tamely shoots and Heurelho Gomes collects easily.

Whistle goes and that's that.

At least Chelsea now have a shot on target.

Diego Costa is arguing that Adlene Guedioura played a back pass to Heurelho Gomes.

A long ball over the top comes to Nemanja Matic, who pokes to Diego Costa and Gomes comes out to stop the Spain striker. He then fumbles the ball and Guedioura does appear to help Gomes collect.

The referee waves away all the protests.

Robert: Chelsea lack creative spark without Fabregas on the pitch. No need to play both Kante & Matic at same time.

Chelsea have seen plenty of the ball, there is lots of nice stuff from Oscar, Pedro and Eden Hazard but the Blues are yet to have a shot on target.

John Terry may be 35 but he does not back out of a challenge. He takes out Odion Ighalo and wins a free-kick.

Miguel Britos takes out Pedro but escapes a yellow card. Watford are hunting for the ball and when they win it Jose Holebas and Nordin Amrabat are causing lots of problems.

Eden Hazard whips in a free-kick but Heurelho Gomes flies out and punches the ball clear. Strong stuff.

Lovely move from Watford.

Etienne Capoue finds Jose Holebas on the left, he slides to keep the ball in and then puts a dangerous ball into the box.

The ball is loose and comes to Adlene Guedioura who blasts it into the stands. No repeat of that goal he scored against Arsenal in the FA Cup.

At the half hour mark and it is Watford who have had the best chances.

Odion Ighalo with the clearest.

Free-kick for Chelsea, near the left touchline.

Eden Hazard curls it in, Branislav Ivanovic gets his head to it, but does not get the contact he was after. Goal kick.

Big chance for Watford.

Nordin Amrabat does not give up.

He charges down the right flank and into the box and Odion Ighalo is so close to making it 1-0 Watford, he gets to the cross but sends it over the goal. 

It's now raining at Vicarage Road.

Antonio Conte goes for a Chelsea cagoule and baseball cap combo.

Just the one shot on target so far in the match and it was Jose Holebas' effort from earlier.

Troy Deeney and Gary Cahill are in the book.

Deeney on Eden Hazard and before that Cahill on Etienne Capoue.

Oscar scuffs a shot wide, sarcastic cheers from the home crowd.

The crowd get going as Nordin Amrabat fights off about three Chelsea players before winning a free-kick.

Watford's seem to like the tactic of pumping the ball down the flanks, maybe they have sensed a weak spot? They are getting a bit of joy against Branislav Ivanovic.

I tell you what Watford look very comfortable in possession and it's no surprise, they seem to have a lot of time on the ball. Not much press from the Chelsea players.
