Hello and welcome to LIVE updates of the Premier League clash between rock bottom Watford and Frank Lampard's fourth-placed Chelsea. Will the Hornets pick up a first win at the 11th time of asking? Or will the young Blues continue their upward trajectory? Kick off 17:30 GMT.

After consultation with the Hornet's medical staff, Cathcart is back on his feet and seems set to continue.

Craig Cathcart is down injured. On comes the Watford physio.

VIDEO: Abraham's opener.

STAT: Watford have not won any of their last nine PL home matches. They have lost four of those encounters.

HIGH FIVE ON THE ROAD? Chelsea are already enjoying a club record of four straight away wins in the top-flight while notching three goals or more. Could they do it again tonight and equal their own record of seven consecutive away triumphs in all competitions? We should perhaps expect more goals anyhow. The Blues's last five PL away matches have involved 27 goals.... Make that 28 and counting?

That really was an outrageous first-time pass in-behind by Jorginho. Quite stunning.

That is Abraham's ninth goal in his last nine outings.

GOAL! Abraham races onto Jorginho's sumptuous curved pass and coolly lobs the keeper.

All Chelsea so far.

HEAD-TO-HEAD: Watford have only managed two victories from the 12 PL clashes between the sides. Indeed, they are the only wins the Hornets have picked up in 21 meetings across all competitions (losing on 14 occasions).

KICK OFF! Chelsea get us underway.

DID YOU KNOW? If Watford fail to beat Chelsea this evening it will be the first time ever they have failed to win any of their first 12 games. The Hornets are already the first club to not win any of their first 10 PL matches on two occasions (this season and back in 2006-07).

STAT: Coming into the weekend, Tammy Abraham had amassed a Premier League-high of six away goals this term. That's more than any Chelsea player managed in the whole of last season.

GERARD'S GOAL-DROUGHT: Gerard Deulofeu's 24 shots without netting is a Premier League-high this term. Indeed, Watford as a whole team have only scored one goal in their past five games in all competitions.

Lampard on Watford: "We cannot underestimate the team. They will be hurting because they haven't won for a while, and will have every ambition to try and win this game, so I certainly have even more focus on what we need to do."

Quique Sanchez Flores on Watford's injuries: "We need to talk about the solutions. The players who are not really ready right now, they're not the solutions. I love Troy Deeney, all of you know how is my relationship with Deeney, he helps the team when he's on the pitch, but right now he's not here, so it's not a solution for me."

It's just the one change from Chelsea's last Premier League outing at Burnley too. Emerson Palmieri is back from injury to make his first appearance since September. He replaces Marcos Alonso.

Watford make just the one change from their goalless draw with Bournemouth. Andre Gray is recalled into the Hornets starting line-up in place of the injured Tom Cleverley.
