Marko Arnautovic nets early winner as West Ham stun Chelsea to hand David Moyes his maiden victory

Little time to dwell on that result at IBTimes UK towers as we move straight onto Saturday's 15.00 GMT kick-offs, a five-strong slate headlined by Tottenham's clash with Stoke at Wembley.

We hope you can stay with us for that one.

Full-time

West Ham 1-0 Chelsea

Fabregas launches a shot into the stands after Kante's cross for Morata is headed away.

Adrian then claims a hopeful delivery from Azpilicueta and Zabaleta hooks the ball clear.

FIVE minutes of added time signalled at the end of this second half. Can Chelsea find a last-gasp leveller?

Masuaku carded for time wasting at a throw-in. West Ham's six yellows will incur a fine from the Premier League.

Reid steps up and Morata is caught offside while looking to collect Azpilicueta's lofted pass. Referee Taylor declines to go back and punish two earlier fouls from Noble and Obiang.

On the touchline, West Ham coach Stuart Pearce is ordered back into his technical area after hoofing the ball into the crowd.

Kante and Morata combine to set up Hazard, who blasts his shot over the crossbar. Time is running out for Chelsea.

Masuaku drops too deep and the flag stays down as Morata collects Kante's deflected pass and shoots into the side netting.

A massive chance for Chelsea spurned by their top scorer.

Antonio has put it one hell of a shift for West Ham this afternoon and lies on the ground exhausted and no doubt suffering from cramp. He eventually trudges off to be replaced by Andre Ayew.

Ogbonna concedes the corner and Morata is penalised for a shoulder on Adrian. Under 15 minutes - plus stoppage time - now remain for Chelsea to find an equaliser.

Pedro Obiang wipes out Kante and West Ham's tally of yellows is up to five. They have certainly taken a physical approach to this London derby.

Christensen tries to turn home Fabregas' free-kick but Reid is on hand to make a superb block.

Moyes' first change sees potential match-winner Arnautovic make way for Diafra Sakho.

Two yellow cards in quick succession for West Ham. Reid brings down Morata in the middle of the pitch and Cresswell kicks the back of Willian as the Brazilian looks to enter the penalty area from the right.

Four home players are now in the book, with Adrian and Arnautovic having previously been cautioned.

Zappacosta is the man to make way for Willian as Conte uses all three of his substitutions inside 65 minutes. Chelsea very attacking now...

Alert goalkeeping from Adrian, who smothers the loose ball after Morata looks to pounce on Azpilicueta's deflected shot.

West Ham, not merely content to defend their slender lead, come forward again but Arnautovic cannot find Antonio. Masuaku wins a corner off Moses, but the delivery is too deep.

Zappacosta and Zabaleta engage in a fierce battle for possession in the far corner. It looks like Willian is going to be introduced with Chelsea's third and final change.

Zappacosta steps inside Zabaleta and onto his right foot before curling a shot narrowly wide of Adrian's far post.

West Ham's shouts for a penalty go unheeded after Arnautovic flicks the ball onto the hand of Christensen. Referee Taylor had a long think about that one.

Conte turns to his bench for the second time already as Moses replaces Alonso.

Arnautovic goes one-on-one with Courtois on the break but the flag is belatedly raised for offside after Antonio delays his pass for a fraction too long.

Fabregas then cannot make a clean contact with Zappacosta's latest cross and Ogbonna clears.

Hazard goes to work for Chelsea and Zabaleta ensures that Zappacosta's floated cross does not reach Alonso. Pedro volleys the loose ball well wide.

The second half is now underway. One change from Conte, who sends on Pedro in place of the consistently underwhelming Bakayoko.

Chelsea simply need more in the final third to try and break down this surprisingly stubborn West Ham backline, who have shipped more goals than any other team in 2017-18.

A very positive opening 45 minutes from West Ham, who lead thanks to Arnautovic's first goal in claret and blue. They have defended stoically throughout bouts of Chelsea pressure and look dangerous on the break with Antonio able to utilise his pace.

Moyes will be hoping for more of the same after the break as he looks to claim a major scalp and collect his maiden win in the job.

The visitors, by contrast, have been sloppy and largely ineffective. A half-time blast of the hairdryer from Conte surely awaits.

Half-time

West Ham 1-0 Chelsea

A number of 'oles' from the home crowd as West Ham continue to frustrate their below-par opponents with some quick passing.

Lanzini's cross is cut out by Alonso as the whistle blows for the end of the first half.

Masuaku wins another corner off Azpilicueta as West Ham close the half in positive fashion.

Two minutes of additional time signalled.

Chelsea survive a couple of corners in quick succession, Courtois comfortably catching an in-swinging cross from Lanzini.

Bakayoko's shot is blocked by Cresswell as Chelsea come forward once more.

West Ham break quickly, with the rapid Antonio putting Christensen under all sorts of pressure. Courtois races off his line and makes an absolute hash of the clearance, skewing the ball out for a needless corner.

Zappacosta is almost punished for some half-hearted effort as Masuaku comes in from the left flank and drags a shot well wide of the far post.

Fabregas clips a pass forward for Hazard and Arthur Masuaku comes across to dispossess the Belgian.

Morata's attempts to win the ball ahead of Reid are deemed overzealous and West Ham have a pressure-relieving free-kick inside their own penalty area.

Chelsea have scored more headed goals than any other Premier League team so far this season (9). Much of that is due to the arrival of Morata, whose aerial prowess is certainly well-established.

On this occasion, he is unable to make proper contact with a cross from Zappacosta and the ball sails harmlessly wide. Good defending from Ogbonna.

Chelsea probe patiently for another opening, but the middle of the pitch is extremely congested.

West Ham, now entirely camped inside their own half, holding firm as it stands with just under 15 minutes remaining until half-time.

A couple of smart low saves from Adrian keeps Chelsea at bay. Kante is the first to try his luck before a short corner ends with a driven left-footed effort from Zappacosta.

Morata is first to the rebound, but came from an offside position. Chelsea very much on top now and searching for an equaliser.

Christensen is very nearly caught out by Arnautovic, who looks hungry for more goals after opening his West Ham account in the early stages.

That was the Austrian's first goal in any competition for eight months.

Cesc Fabregas tees up Bakayoko with a wonderful pass and the Frenchman's low strike is blocked by a combination of Ogbonna and Aaron Cresswell.

West Ham try to launch a quick counter-attack, but Cahill and Christensen snuff out the threat of Antonio.

West Ham's commitment to applying relentless pressure at the top of the pitch almost forces Courtois into an error.

At the other end, Hazard fires a volley wide after an initial cross is headed high into the air by Ogbonna.

Azpilicueta sends a deep cross towards the back post and Adrian spills the ball while trying to soar above Morata. He regathers it and is knocked over by compatriot Alonso, who receives a yellow card for his troubles.

That looked a tad harsh, it must be said.

No rhythm whatsoever from Chelsea early on. West Ham are pressing well and mostly keeping them penned into their own half.

Morata throws himself to the turf under minimal contact from Reid and appeals in vain for a penalty.

There did appear to be a little shirt pull from the New Zealand centre-back, but that was never likely to be given.

N'Golo Kante tries to pick out Hazard with a searching pass forward but the ball runs through to Adrian.

Nothing doing for Chelsea thus far.

Gary Cahill brings down Antonio and West Ham have another free-kick in a wide position.

Lanzini flights the ball into the box but the whistle blows for a foul on Alonso by Angelo Ogbonna.

Six minutes gone and West Ham take a surprise lead. Arnautovic plays a lovely give-and-go with Lanzini and stands up Cesar Azpilicueta before bending a shot beyond Thibaut Courtois and into the bottom corner.

What a start for the hosts.

Goal: West Ham 1-0 Chelsea (Marko Arnautovic)

It's been a positive start from West Ham, who look full of energy and purpose.

Tiemoue Bakayoko limps away from a painful challenge with Pablo Zabaleta.

Manuel Lanzini is barged over by Zappacosta and West Ham have a free-kick in a good position wide left.

The Argentine's floated delivery is firmly headed away by Andreas Christensen.

The teams have emerged from the tunnel and referee Anthony Taylor gets the first Premier League derby of the weekend underway. East and West London collide.

Chelsea, decked out in white, will kick from right to left in this first half as we look at it.

Kick-off is now less than 10 minutes away on a cold December afternoon in east London...

Yes. I think it's a good problem for West Ham. I don't know if it's a good problem going into the World Cup, but it's a good problem for West Ham. I would like to have those problems in a few other positions here at West Ham.

I've got a couple of positions where I've got lots of people vying for the job and I've got other positions at West Ham where we don't have people vying for the job. But at goalkeeper, when I came in I was aware of Adrian, obviously I'm well aware of Joe so I'm happy with having the two of them.

- Moyes on his Hart/Adrian conundrum

That unpleasant record had been held by John Gorman since Swindon's doomed 1993-94 campaign. It is also worth noting that Moyes' last game in charge of Sunderland was a 5-1 mauling at Stamford Bridge in May.

Here is what Moyes had to say when asked if West Ham were now beginning to look like more of a team made in his own image following their battling performance at the Etihad Stadium last Sunday...

Well it's early days so I wouldn't want to get too carried away. But I've got to say that the players have been really good, they've tried to take on board everything we've asked of them, they're doing the work.

As I said right from the start, they'll have to do the work if they want to play and hopefully they're all doing that and things we hope will improve, but we'll also improve once we get a few players back from injury as well.

I think we played well at Manchester City. I think we were good without the ball, and when we got the ball we were OK. I'd like to be much better when we get the ball but hopefully that in time we can work towards that.

Ultimately we have to try and stop conceding goals. We done it with a little bit of a patched up defence last week so I hope that when we get some of the players and some of the senior players back it will give us an even better chance.

But does a summer transfer to Real Madrid beckon in 2018?

On a favourable run of fixtures that sees Chelsea take on Huddersfield, Southampton, Bournemouth, Everton, Brighton and Stoke between now and the New Year, the Italian added...

It's a good period if we are able to win. Now we have to play two games away, against West Ham and then Huddersfield. West Ham is a good team. To play away against Huddersfield is not simple. United lost the game, Manchester City struggled a lot.

This league is very tough, especially because there is a team that is doing an extraordinary path.

Conte refused to discuss the respective futures of Luiz and Eden Hazard during Friday's pre-match press conference at Cobham, but admitted that it was odd to see West Ham struggling so badly given the apparent talent at their disposal.

It's a bit strange to see them in this position in the table. For sure they have the potential to do better. I hope not from tomorrow, but after our game. For sure this team is a really good team with good players.

The headline news from a Chelsea perspective is that Morata starts. Conte's only change from the midweek draw with Atletico sees Marcos Alonso preferred to Victor Moses, with Davide Zappacosta remaining in the first XI.

17-year-old defender Ethan Ampadu comes onto the bench.

As expected, Adrian retains his starting berth as Hart has to settle for a place among the substitutes. Such a switch, if enforced for the long-term, could have a devastating impact upon the latter's World Cup hopes.

Reid and Noble also return for West Ham as Declan Rice and Edimilson Fernandes drop to the bench, where they are joined by Hernandez and Carroll.

Marko Arnautovic starts with Kouyate ruled out. Youngsters Ben Johnson, Nathan Trott, Domingos Quina and Toni Martinez are all removed from the matchday squad after being involved at City.

Official lineups are imminent. Stand by...

David Luiz remains unavailable for Chelsea due to a knee injury, while Danny Drinkwater is ill.

Conte is also rumoured to be sweating on the fitness of striker Alvaro Morata, who was said to have been sent for a scan after pulling up in a final pre-match training session on Friday.

Rival reports say he has simply been struggling with a fever and boarded the team bus as usual.

Moyes is expected to retain faith in Adrian today despite Joe Hart being available for selection once more after he was ineligible to feature against City per the terms of his season-long loan.

Javier Hernandez could return after five weeks out with a hamstring injury, while fellow striker Andy Carroll is also back in contention following a knee problem.

Centre-backs Winston Reid and James Collins may similarly be deemed fit enough to play after injury, while Mark Noble and Michail Antonio should shake off minor knocks.

Cheikhou Kouyate, Sam Byram and Jose Fonte are all sidelined, meanwhile.

West Ham United vs Chelsea - an inevitably feisty lunchtime London derby that pits together two rivals currently at opposite ends of the form table.

Unbeaten in seven and winners of their last six, the visitors, who fought back to draw 1-1 with Atletico Madrid on Tuesday and finish as runners-up in Champions League Group C, remain third but another victory today would see them draw level with second-place Manchester United and within eight points of leaders Manchester City ahead of tomorrow's eagerly-anticipated clash at Old Trafford.

By contrast, the hosts currently lie 19th and three adrift of safety after a woeful run that has seen them lose five of their last eight matches. Per Opta, 10 points from 15 is their worst-ever start to a campaign in the Premier League era and they last went nine without a win in 2010-11, when they were relegated to the Championship.

Although slightly more resilient under new boss David Moyes if you discount the humiliating defeat by former club Everton, the much-maligned Scot is still awaiting his first win as West Ham manager after three losses and a draw. He will likely be eyeing upcoming matches against Stoke City, Bournemouth, Newcastle United and West Bromwich Albion as more favourable opportunities to end that sequence rather that back-to-back meetings with Chelsea and Arsenal.

The odds are firmly stacked in one team's favour today, although the Hammers, sunk by a late City winner last time out, can at least take some optimism from the fact that exactly half of Antonio Conte's eight league defeats as Chelsea manager to date have come in London derbies. Fellow strugglers Crystal Palace provided the blueprint for how to shock them as recently as October, of course.

Stay tuned to IBTimes UK for all the latest team news ahead of the first instalment of a big weekend of top-flight derbies. Minute-by-minute updates to come after kick-off at 12.30 GMT.
