GOAL! CHELSEA! MOSES! A great ball form deep finds the Nigerian's run in behind and he controls well before nudging the ball past Ryan to make it four.
GOAL! CHELSEA! HAZARD! Willian sets the Belgian away in the inside left channel and he drives at Goldson before coming inside and firing back across Ryan and into the corner from the edge of the box. Too easy!
A double change for Brighton as Gross and Hemed make way for Kayal and Murray.
66'
CHANCE! Alonso fails to clear following Rudiger's header, allowing Schelotto to chest the ball down and find himself one-on-one with Caballlero but the goalkeeper spreads himself well to block the effort.
61'
Luios blocks March's long-range effort away to safety.
58'
Willian steps up to the free kick and Ryan just about tips his effort against the post! Great save!
Brighton want a penalty as Schelotto is felled by Bakayoko but Jon Moss once again says no.
33'
Shane Duffy heads just wide from a corner after Chelsea carelessly gave the ball away from their own goal kick. This game might not be as much of a foregone conclusion as it seemed 20 minutes ago.
30'
CLOSE! Great save from Caballero as he somehow gets a hand to Hemed's header from Gross' cross from the right to maintain Chelsea's two-goal lead.
28'
Chelsea go close again. They nick the ball of Brighton on halfway and counter. Hazard feeds Batshuayi but after cutting onto his left foot his effort is too close to Ryan and the keeper makes the save.
26'
Chelsea counter and Hazard feeds Willian on the right but his powerful effort is turned away by Ryan at the near post.
25'
Brighton continue to threaten from set-pieces but Chelsea deny Duffy a free header on goal on this occasion.
20'
Caballero looks like an accident waiting to happen today. Minutes after he could have given a penalty away he flaps at a couple of corners, giving Brighton hope that they can exploit the absence of Thibaut Courtois.
18'
Ryan shovels Bakayoko's low effort from the edge of the box around the post.
16'
Caballero does well to palm away a cross form the left with Gross looking head home before Schelloto goes down under a challenge from the goalkeeper but Jon Moss is unmoved.
14'
March shoots low from 25 yards but Caballero is equal to it.
12'
Brighton see off a corner as Chelsea continue to go for the throat.
10'
It's all Chelsea at the moment. This is a big 10 minutes for Brighton, they really need to get through it unscathed or this could get embarrassing.
GOAL! CHELSEA! WILLIAN! Brighton give the ball away and they are punished in some style. Willian Hazard and Batshuayi combine with the latter back-heeling the ball into space for the Brazilian to smash home from the edge of the box. What a start!
GOAL! CHELSEA! HAZARD! Moses crosses low from the right and the ball falls to the feet of Hazard who shimmies to the right before powering the ball past Ryan from 12 yards. Just the start Chelsea wanted!

Chelsea get us underway here after a tribute to the late Cyril Regis.
Start of match

The players emerge from the tunnel and we will be underway shortly.

Chris Hughton's thoughts pre-match: “We have had a decent level of performance against the top teams, but we haven’t scored any goals against them, and so we haven’t won any of the games. So sometimes as a manager you try to do something a little bit different. We are at home, we have a chance in every game. We will certainly have a go.”
PRVW
Antonio Conte's thought pre-match: “Every game is different. We will try to be focused offensively, and focused defensively. We will try to get three points, it’s the most important thing today.”
PRVW
Brighton did of course complete a club record deal for PSG's Jurgen Locadia late last night but he is unavailable for this one after missing the Premier League's registration deadline.
Interesting team selections today. Brighton opt to go with a back five, matching up their opponents, whilst the visitors name Michy Batshuayi in the startling lineup in the absence of the suspended Alvaro Morata, suggesting that the Belgian is not set for an imminent January exit.
Hello and welcome! Chelsea go into this one today looking to move joint on points with Manchester United in second ahead of their game with Burnley a little later on, whilst Brighton are looking to increase the gap between themselves and the bottom three to six points.
