89' The free-kick is aimed towards Carroll but James gets his head to it first.
88' James catches Longstaff on the boot with his tackle at full stretch. The Newcastle midfielder is in a bit of pain but is soon back to his feet and will be looking to make the most of this free-kick...
85' A couple of crosses into Chelsea's box are dealt with. Lampard is readying a third and final change, with Giroud the man coming on.
84' Ziyech's latest cross is plucked out of the air by Darlow. Newcastle are offering next to nothing and could do with the full-time whistle.
82' Hudson-Odoi plays a nice one-two with Abraham and his first-time shot is blocked on the edge of the box.
81' MENDY SAVE! Almiron's shot takes a big deflection and Mendy takes no risks as he slaps the ball out of play for a corner. The Newcastle set-piece comes to little.
78' Chilwell watches Ziyech's cross all the way but his first-time pass into the middle is overhit and goes out of play for a goal-kick.
76' Werner would have liked a goal today but he will have to settle for an assist. Hudson-Odoi is the player to replace him.
75' GOAL DISALLOWED! Werner latches onto Ziyech's throughball, knocks it past Darlow and slots into an empty net. He wheels away to celebrate but the offside flag, rightly, goes up.
68' Joelinton thinks he is in behind but a delayed offside flag goes up. Almiron has looked lively since being introduced from the bench.
67' Tammy Abraham has scored 23 goals in all competitions since the start of last season, which is 11 more than any other Chelsea player.
65' GOOOAAAALLL!!! NEWCASTLE 0-2 CHELSEA! The visitors finally have their second goal - and it has come during their opponents' best spell of the game. Werner carries the ball past three opposition players, slides it through for Abraham and the striker calmly converts for his fifth goal of the campaign.
63' With a little over an hour played, Newcastle have still yet to register an attempt on target. Chelsea could easily have scored four or five but instead they have just the one goal - and even that was scored by an opposition player.
57' Chelsea striker Timo Werner could become just the fourth different German player to score in three consecutive Premier League matches, after Jurgen Klinsmann (three times), Dietmar Hamann (in March 1999) and Leroy Sane (in October 2017).
55' CLOSE! Zouma leaps highest and gets to the corner ahead of Schar but cannot keep his powerful header on target. It still somehow remains 1-0!
54' POOR FROM WERNER! It is a horror moment for Schar as he takes far too long to clear the ball and Werner takes it off him. The Germany international only has Darlow to beat - again - but tries to square for Ziyech and the pass is cut out.
52' Chelsea striker Timo Werner could become just the fourth different German player to score in three consecutive Premier League matches, after Jurgen Klinsmann (three times), Dietmar Hamann (in March 1999) and Leroy Sane (in October 2017).
50' Lampard's men have not really found their rhythm early in the second half. Newcastle are getting into their opponents' faces far more but need to start creating some chances.
48' Lascelles came out for the second half in his kit but soon decided he was unable to play any part. Schar, as expected, is positioned between Clark and Fernandez, whose own goal separates the sides.
46' RESTART! Newcastle get us back under way at St James' Park. Chelsea have not lost a Premier League game when leading at half-time since December 2018 away at Wolves.
45' + 2' HALF-TIME: NEWCASTLE UNITED 0-1 CHELSEA
45' + 1' Lascelles has gone to ground for a second time. One minute has been added on but that will likely be doubled to account for this latest stoppage.
45' Murphy barges into the back of Mount and referee Craig Pawson, who could not have been better positioned, reaches into his pocket for the second time today.
44' Lewis hangs up a cross to the back post and Murphy heads down towards the penalty spot. There is nobody in a black and white shirt waiting to get on the end of it and Chelsea clear their lines.
42' Newcastle are up to 21 per cent possession now - a slight improvement on the opening 20 minutes! The hosts have had a couple of promising opportunities in the first half but Chelsea will feel they should be two or three goals ahead.
33' The home side are starting to be a little braver with their play. It may well be that Werner's big miss a little earlier proves to be a turning point in the match.
31' BETTER FROM NEWCASTLE! The ball drops nicely for Longstaff to strike but he instead passes to Saint-Maximin. The winger's attempted flicked pass to Joelinton runs through to Mendy. For the first time today, Chelsea were caught out at the back there.
29' BIG CHANCE! Chelsea's pressing pays off as possession is turned over high up the pitch once again. Mount feeds the ball to Abraham and he plays in Werner, who has just Darlow to beat. The striker is too precise with his finish, rolling the ball inches past the post.
27' SHOT! Kovacic gives the ball away in midfield and Joelinton has a chance to run at Chelsea's exposed defence. Instead of doing that, though, he tries to beat Mendy from just inside his own half but scuffs the shot well off target.
23' CHANCE! Ziyech sends in another delightful cross form the right. Werner stays onside and looks certain to tuck it away near the front post, but he is unable to make clean contact with the ball.
21' The home side have a chance to counter but they are far too slow in getting the ball forward and Chelsea get every player back. Incidentally, it has been 11 months since Newcastle won a Premier League match that they conceded first in.
19' Newcastle have had just 19 per cent of the ball so far. If their plan was to sit deep in the hope of snatching a point, Steve Bruce will surely need a tactical rethink. Chelsea are looking in the mood for a second.
17' No player has scored more Premier League own goals since Federico Fernandez's Newcastle United debut in August 2018 than he has - five, level with Brighton and Hove Albion's Lewis Dunk.
15' Werner uses his pace to get in behind. The angle is against him and he instead attempts to square the ball for Abraham, but the pass is just out of his team-mate's reach at the back post.
The perfect start! 🙌#NEWCHE pic.twitter.com/6OFBhSYLNn

13' Chelsea's goal was deserved on the basis of the opening 10 minutes - they have dominated from the off. Newcastle have been incredibly deep but are now pushing forward, with Manquillo's shot from the edge of the box blocked.
11' Fernandez argued he was fouled by Chilwell when attempting to clear the ball but the goal is allowed to stand following a VAR check.
10' GOOOAAALLL!!! NEWCASTLE 0-1 CHELSEA! Mount is played in by Werner on the overlap and he fizzes the ball across goal. Fernandez, under pressure from Chilwell, is unable to adjust his feet and the ball goes in off his knee. A comical own goal!
9' ANOTHER SAVE! Darlow is quick to react again, this time to push Abraham's header over the crossbar after the striker glanced Ziyech's inswinging cross on goal.
8' Abraham holds up the ball inside the box and tees up Kovacic to blaze over. James also had a shot blocked by Manquillo before that in what has been a dominant start from the visitors.
6' Chelsea have already settled into a nice rhythm. They are knocking the ball around in search of an opening and, having already come close through Werner, you would not bet against them finding a breakthrough soon.
4' BIG SAVE! Kovacic turns over possession and Kante takes over by poking the ball through for Werner. The Germany striker's angled drive towards the bottom-right corner is pushed around the post by Darlow.
