Willian is called up for a foul throw. Conte looks furious.

Hazard finds Moses on the right, but Ayew wins the ball from him. Great repsonse fromt he sub.
The ball falls to Fabgreas around 25 yards from goal, but he shoots high and wide.
West Ham are still golding on, absorbing the pressure. Could this be remembered as the day Chelsea surrendered their Premier League title defence?
There will be five minutes of stoppage time.
Masuaku is booked for timewasting, too.
Stuart Pearce hoofs the ball into the crowd when it comes into the technical area! He gets a ticking off from the ref.
Azpilicueta puts a ball over the top to Morata in the box, but the flag is up.
CHANCE: Morata feeds Hazard on the edge of the box with a great flick, but the Belgian shoots high and wide! Another glorious chance!
CHANCE: Kante picks out Morata wth a superb thorugh ball and the Spaniard is played onside by Masuaka. He volleys wide with a very powerful shot! That was a huge chance to equalise!
West Ham break with Ayew, who fails to pick out the advancing Sakho with a wayward forward pass. That could have been very dangerous.
SUB: Antonio is replaced by Ayew.
Antonio goes down injured, and he's in no hurry to get up. A substitute is being lined up...
Adrian spills a Fabregas corner, but the ref says the 'keeper was fouled by Morata.
Shots on target in the second half: zero.
Hazard sees a low cross cleared by Reid. Depsite Moyes' concerns about being able to mark him, the Belgian has been kept fairly quiet today.
Arnautovic was superb today - that was quite possibly his best performance for the club thus far.
That's Sakho's sixth consecutive appearance from the bench in the Premier League.
SUB: Arnautovic makes way for Sakho.
Christensen gets a shot off from the resultant free kick, but Reid blocks.
Willian gets past Cresswell just outside the box on the right, but the Hammers man scythes down the Brazilian. It's a caution for a man who has done little else wrong today.
Reid sees yellow for a challnge on Morata.
Pedro appears to perform a terrible foul throw but gets away with it.
SUB: Zappacosta makes way for Willian. Another positive change from Conte.
Masuaku tries to beat Moses on the left flank and wins a corner for his troubles. Lanzini's inswinger has too much on it and finds no one.
Azpilicueta shoots through the crowd from 25 yards and it deflects off of Cresswell into Adrian's arms.
Zabaleta and Zappacosta fight for the ball near the Chelsea corner flag. Zabaleta is penalised for a foul. So Zappacosta is ZZ Top in that battle. (Sorry.)
West Ham settle down and hold possession for the first time in a long time.
Adrian gets his name in the book for timewasting while lining up his goal kick.
CHANCE: Zappacosta cuts in on his right foot and shoots from around 25 yards. It goes narrowly wide.
Fabregas plays the free kick short to Moses, but there are too many claret shirts in the way.
Morata is felled by Obiang around 35 yards from goal. Free kick.
SUB: Victor Moses comes on for Alonso. Zappacosta, therefore, switches sides and goes to wingback.
Arnautovic breaks on the left and beats Christensen, who handles the ball in the area. Arnautovic wants a penalty, but either the ref didn;t see it, or he didn't feel it was intentional.
Morata gets a yard on his defender when chasing a long ball, but is offside.
Zappacosta sees another cross cleared by Ogbonna. West Ham are dealing with all aerial assaults in the area very well.

With that substitution, Conte appears to acknowledge that Chelsea need 33% more attacking thrust and 50% fewer holding midfielders.
SUB: Pedro replaces Bakayoko.
Anthony Taylor gets the party start and Lanzini kicks off.
The ref blows up for half time. West Ham have looked inventive and positive, although they have sat back on the lead for large periods. Could this be David Moyes' first West Ham win?

Noble tries to find a teammate but Cahill clears as far as Arnautovic, whose shot does not trouble Courtois.
Masuaku puts a cross in from the left and wins a corner. The home side are, understandably, in no rush to take it.
Antonio chases down a ball forward and Courtois is forced to come out and clear. He makes a mess of it and clears for a corner, instead of a throw.
Cahill puts in a cross from the left but it's aimless and goes out for a goal kick. West Ham are sitting very deep at the moment, inviting the Chelsea pressure.
Masuaku takes the ball off of Zappacosta's toe and has a shot from distance, which trickles wide. The Italian had no idea the ball was about to be taken from him in a dangerous area.
Morata blasts a loose ball over the bar. Chelsea are definitely enjoying more possession, but West Ham are nullifying everything they do in the final third.
Zappacosta sends in a cross from the right but Morata heads wide after out-jumping Ogbonna. The Spaniard should have done better there.
Chelsea's subs are passing a hot water bottle among them. Don't they have enough resources to buy more than one?

Bakayoko is playing in a very advanced position. He's virtually a No. 10 at times.
Fabregas finds Bakayoko in space in the area with a lovely pass along the floor, but Bakayoko's shot is blocked.
Zappacosta goes to ground with very little contact from Masuaku. We've seen two fairly blatant unpunished instances of simulation, but Arnautovic gets a yellow card for celebrating with the fans. Where's the justice?
CHANCE: Azpilicueta sends in a powerful cross for Morata. Ogbonna clears as far as Hazard, who volleys just wide.
Azpilicueta sends in a cross from deep and Adrian claims it before Morata can put a header on it. But Adrian drops it and he is fouled by Alonso before reclaiming. Alonso is booked for his troubles.

And we're off! Referee Anthony Taylor peeps the whistle as Morata takes the first touch.
Kick-off is moments away. Chelsea have won their last seven Premier League matches played in th emonth of December.
West Ham United have now gone eight league games without a win. The last time they went on a nine-game winless run, in 2010-11, they were relegated.
Frank Lampard is the leading scorer in this fixture, with five goals between 2005 and 2013. They were all for Chelsea.
Thibaut Courtois: "West Ham are a better team than their position in the league shows, they are struggling but they made it difficult for Man City and we expect a very tough game."
West Ham can move out of the relegation zone, albeit temporarily, with a draw today.
For all the criticism of West Ham as an organisation, they certainly know how to take an arty picture of bubbles.
Moyes hasn't managed a win in his first four games as West Ham manager. It took him eleven games to get one at Sunderland.
Eden Hazard has scored in his last two outings against The Hammers.
David Moyes isn't sure he has someone capable of either marking Eden Hazard, or following him into a toilet:
"There are occasions when I would consider man-marking, Hazard is a player who would definitely come into that category. The problem is that I don’t know if I have got someone who is that type of player to be a man-marker. You’ve heard the saying ‘if he goes to the toilet, follow him’. I don’t know if I have got that."
Antonio Conte: "This league is very tough, especially because there is a team [Man City] that is on an extraordinary path. West Ham has a good squad with good players. To see them in this position is a bit strange."
A glimmer of hope for the home side today: David Moyes has won four out of his last five Premier League home matches against the reigning champions. The Scot was victorious on all three occasions on which the opposing manager was Italian (Carlo Ancelotti, Roberto Mancini and Claudio Ranieri).
Apparently, you may want to expect a Chelsea goal between the 21st and 30th minute...
West Ham have scored 13 Premier League goals this season.
Moarata and Hazard have 14.
Winston Reid is back for West Ham and Chicharito has returned to the bench, but the biggest talking point for the Hammers is the exclusion of Hart. It will undoubtedly be a popular decision with fans, but have we officially passed the point where he is England's number one?
WEST HAM: Adrian, Zabaleta, Reid, Ogbonna, Cresswell, Obiang, Noble, Arnautovic, Lanzini, Masuaku, Antonio. Subs: Hart, Rice, Fernandes, Sakho, Ayew, Chicharito, Carroll. /// CHELSEA: Courtois; Azpilicueta, Christensen, Cahill, Zappacosta, Bakayoko, Kante, Fabregas, Alonso; Hazard, Morata. Subs: Caballero, Rudiger, Ampadu, Moses, Willian, Pedro, Batshuayi.
After an impressive turn in the Champions League, Davide Zappacosta gets the nod over Victor Moses. Alvaro Morata will front a strong-looking Chelsea side.
Adrian starts over Joe Hart for West Ham, who boast no fewer than four forwards on their bench. Mark Noble is back with the captain's armband.
