NO GOAL! Koscielny has headed home, but the goal will not count, with Kolasinac having drifted offside in the build up.
90' +1
There will be a minimum of three minutes stoppage time. Torreira whips in a corner, but Fabianski is out to claim it.
89'
A swift West Ham counter sees Noble find Snodgrass, who aims a cross to Carroll at the back post. The delivery is over the striker, though, with Bellerin doing well to prevent Carroll attempting anything acrobatic.
87'
Other than a flurry of activity when Ramsey was introduced, Arsenal have offered little in the second half, and if anything, West Ham look more likely to add to their lead than conceding at the other end.
84'
Fantastic defensive work from Felipe Anderson, who has been superb for West Ham today. He chases back to prevent Ramsey getting clear, halting another attempted Arsenal attack.
82'
Pedro Obiang enters the game and replaces M. Antonio.
A final change for West Ham, and it's a defensive one. Antonio's race is run, as he makes way for Obiang, who will likely slot into midfield, with Snodgrass moving wide.
80'
West Ham are applying good pressure to Arsenal’s defence, preventing the visitors playing their way into midfield and building some momentum.
77'
London Stadium has not been renowned for its atmosphere since West Ham moved in at the start of 2016-17, but – on what is the Hammers’ 50th league game at the ground – the home crowd are in fine voice as their side look to hold onto their well-earned lead.
75'
Snodgrass lofts a tidy cross to the back post, but Antonio is caught on his heels, and fails to get there. Arsenal bundle their way clear through Iwobi, who leads a counter, but West Ham’s defence get back in place to stem the danger.
Minute
Description
74'
Great work from Carroll, who holds off Sokratis’ challenge before forcing the defender to barge into him from behind, winning a free-kick that relieves the pressure on West Ham’s line.
71'
R. Snodgrass enters the game and replaces S. Nasri.
A. Carroll enters the game and replaces M. Arnautović.
Ramsey has forced a corner, and West Ham will use the break in play to make a double change of their own. First, Nasri – who has capped a fine display with an assist – makes way for Snodgrass.
The second change sees Carroll, whose height and aerial prowess will be useful in defence as well as attack, replace by Arnautovic, who makes a point of waving to the West Ham crowd before making his way off. That was no normal reaction to a substitution, and given West Ham do not play at home until January 29, could that well be a goodbye from the Austrian?
69'
Héctor Bellerín enters the game and replaces A. Maitland-Niles.
A third and final change now from Emery. Maitland-Niles has had a decent game, but Bellerin is now on, and the Spaniard will offer another attacking outlet down the right flank.
62'
Brilliant play by Maitland-Niles, who gets the better of Felipe Anderson down the right and squares it to Ramsey, who creates a yard of space before lifting a cross to the far post. Aubameyang is there to meet it, but cannot keep his header down.
60'
S. Kolašinac gets yellow.
The change in shape for Arsenal will leave their full-backs more exposed, however, and Kolasinac will now have to tread a fine line, with the former Schalke man having just received a booking for a late lunge on Antonio.
59'
A. Ramsey enters the game and replaces S. Mustafi.
L. Torreira enters the game and replaces G. Xhaka.
The second change sees Mustafi replaced by Ramsey, so there will indeed be a change in shape, likely to a 4-3-3 or a 4-2-3-1 system.
Well, no time wasted from Emery. He is making a double change, and the first Arsenal substitution sees Xhaka make way for Torreira.
57'
Felipe Anderson turns on the style with a sublime run in from the right, taking on several Arsenal defenders before trying to flick the ball into Nasri, although he doesn’t generate enough power on his attempt and has to instead go back out wide, winning a corner. The home crowd have enjoyed the Brazilian’s performance so far.
55'
Guendouzi finds space 20 yards out, and elects to try his luck with a low strike, but the youngster drags his effort across goal, and Fabianski will collect the ball for a goal-kick.
54'
Emery may now switch shape as he looks to get Arsenal back into the game. The Gunners have plenty of quality on the bench, not least Ramsey, who has been in fine form when uses as a substitute this term, while Torreira would add some guile and craft into midfield.
50'
Arsenal look to respond quickly, Lacazette driving into the area before drilling a cross towards Aubameyang. It takes a deflection, and Fabianski has to react sharply to prevent the ball trickling into the bottom corner.
48'
D. Rice has scored a goal for West Ham United! Assist by S. Nasri.
GOAL! West Ham take the lead thanks to Rice! He missed a gilt-edged chance on the stroke of half-time, but the youngster now has his first Hammers goal, having hammered home into the corner from the centre of the box.
Rice’s first-time finish was precise, but Nasri must take credit for his quick-thinking. He has shined for West Ham so far, and after Arsenal failed to clear from Felipe Anderson’s cross, the Frenchman reacted sharply to tee up his team-mate.
46'
S. Mustafi gets yellow.
We are back up and running or the second half at London Stadium!
No changes for either side at the break, although there has been a switch between the officials. Stuart Attwell was fourth official in the first half, but linesman Andy Halliday has now taken that role, having felt unwell, meaning Attwell will run the line.
Straight away, West Ham are on the front foot, with Felipe Anderson drawing a clumsy foul from Mustafi, who picks up the game’s first yellow card.
45' +1
HALF-TIME: WEST HAM 0-0 ARSENAL.
41'
High and wide from Antonio, who has switched back to the right following a short spell on the opposite flank. Noble’s pass sets Zabaleta away, and the veteran finds Antonio, who cuts in onto his left foot, only to send an effort into the crowd.
30'
West Ham have upped their intensity in recent minutes, and slick combination play between Nasri, Felipe Anderson and Arnautovic results in the Austrian getting into the box. He lets rip with a shot, but Mustafi is on hand to make a last-ditch block.
28'
Nasri has looked West Ham’s greatest threat so far, and the Frenchman will surely be keen to impress against his former club. He is getting jeered by the travelling Arsenal fans whenever he gets on the ball, with the Gunners support evidently not having forgiven the playmaker for the manner in which he left them to join Manchester City in 2011.
22'
That’s great defensive work from Rice, who charges back to prevent Lacazette latching onto Kolasinac’s cut-back, after the wing-back had found space down the left. West Ham are looking rather stretched at the back, and need to get a foothold back in this game.
20'
Lacazette is starting to pull the strings for Arsenal now, dropping off so that Aubameyang can look to run in behind and stretch West Ham’s defence, with Iwobi also offering a threat. In comparison, Arnautovic has been restricted to just 15 touches at the other end.
15'
Arsenal have just started to click into gear now, with Lacazette involved again as he lays a neat ball off to Guendouzi, who plays in Aubameyang. The youngster’s pass forces the league’s leading scorer wide, though, and all he can do is clip in a cross from which Lacazette sends a looping header over.
11'
Felipe Anderson has been on the fringes of things so far, with most of West Ham’s play coming down the right flank. However, after Arsenal fail to clear a corner, the former Lazio winger gets on the ball and cuts in on his left foot as space opens up in front of him, but he fails to keep his effort on target.
9'
A first sighting of goal for Arsenal, now. A long ball from Xhaka exposes West Ham’s defence, with Lacazette expertly bringing it under his control before unleashing a snapshot from the edge of the area, but Fabianski is able to watch the strike sail over his bar.
8'
Arnautovic is furious with Antonio, after the winger wastes a good chance to get the ball into him. Nasri did well to evade a challenge and set Antonio clear down the right, but the former Nottingham Forest man dallies over his next move, allowing Arsenal’s defence to recover.
3'
Arsenal have failed to win their last four away league games, and it is West Ham who have managed to get on the front foot and keep hold of the ball in the opening stages. Arnautovic drifts wide to try and create space for Antonio, but the winger can't latch onto a throughball which would have put him through on goal.

KICK-OFF! We are up and running in the first Premier League match of the day. West Ham have got proceedings underway.
Hello! Welcome to our LIVE commentary of Arsenal’s Premier League encounter with West Ham. Stick right here for all the action as it happens from London Stadium!
After a break for the FA Cup, it’s back to the rough and tumble of the Premier League this weekend. West Ham enjoyed a good December, winning five of their seven fixtures, but relied on Marko Arnautovic’s double to rescue a point against Brighton and Hove Albion in their first outing of 2019.
Arnautovic also scored in the Hammers’ FA Cup win over Birmingham City, and has recovered from a knock sustained in that game to start today. The Austrian’s brother – and agent – said this week that the striker wishes to leave the club, having received an offer from an unnamed Chinese side. However, West Ham subsequently issued a statement insisting their star player is not for sale.
Arsenal, meanwhile, responded in fine fashion to their heavy defeat at Liverpool by hammering struggling Fulham in their last league fixture. A comfortable 3-0 win over Blackpool in the FA Cup followed, and Unai Emery’s side would, temporarily at least, move level on points with fourth-place Chelsea should they win.
WEST HAM SUBS: Andy Carroll, Robert Snodgrass, Adrian, Pedro Obiang, Aaron Masuaku, Lucas Perez, Grady Diangana.
WEST HAM (4-2-3-1): Lukasz Fabianski; Pablo Zabaleta, Issa Diop, Angelo Ogbonna, Aaron Cresswell; Mark Noble, Declan Rice; Michail Antonio, Samir Nasri, Felipe Anderson; Marko Arnautovic.
ARSENAL SUBS: Petr Cech, Hector Bellerin, Aaron Ramsey, Lucas Torreira, Stephan Lichtsteiner, Nacho Monreal, Eddie Nketiah.
As mentioned, Arnautovic retains his place at the spearhead of Manuel Pellegrini’s attack despite his apparent desire to leave this month, while he is supported by former Arsenal star Nasri, who makes his Premier League debut for West Ham after signing as a free agent. The big news for the Gunners is that there is no place in Emery’s squad for Mesut Oil, despite the playmaker having overcome a knee injury. Ramsey, who has reportedly agreed a deal to join Serie A giants Juventus at the end of the season, is on the bench.
The teams are out on the pitch at London Stadium, and we are just moments away from kick-off in this derby!
Both teams can be fairly satisfied with their efforts in the first half, but the quality in the final third has been lacking. Lacazette has looked Arsenal’s sharpest player, although West Ham could have been ahead had Rice done better with his header just moments before the interval.
Both managers will be demanding more cutting edged from their respective sides after the interval. While Arsenal will look for Aubameyang and Iwobi to get more involved, West Ham will aim to keep Nasri – who has looked bright – at the centre of their play.
What a win for West Ham! A goal from Declan Rice – who put in a superb display – has sealed the points for the Hammers, who move up into eighth place.
Well, that’s all from me for now. Until next time, thank you and goodbye!
Arsenal stay in fifth, but their second successive away defeat means they remain just three points above Manchester United, who play Tottenham on Sunday. Unai Emery’s side were far from at their best, and with the manager’s admission January additions will be restricted to loans, the Gunners are somewhat stuck in a rut.
