Chelsea 2-1 West Ham: Premier League as it happened

Antonio Conte marks his first Premier League game with three points. Questions will be asked how Diego Costa and N'Golo Kante stayed on the pitch after avoiding second bookings, but Chelsea get their season off and running with a deserved win.

Full-time: Chelsea 2-1 West Ham

A bit of a melee breaks out in the Chelsea box with West Ham players queuing up to have a crack on goal, but Courtois makes an important block. The Hammers recycle the ball and force it out wide the cross that comes back in is comfortably collected by the Chelsea goalkeeper.

Four minutes of time added on here and Payet has just miss hit an effort inside the box, making the save easy for Courtois.

Costa nets what will surely be the game's winner! Batshuayi nods the ball onto Costa who has time to look up and assess his options with James Collins standing off him. He has Pedro free off to his right but instead opts to shoot from just outside the box, arrowing one into the far corner, sparking some fairly mental celebrations from Antonio Conte.

Goal! Chelsea 2-1 West Ham (Diego Costa, 88)

I owe Victor Moses an apology, his first contribution is a beauty of a cross in from the left that looks destined for Batshuayi in the box. Just as he pulls back to shoot, Reid nods away, but only as far as Pedro who lashes one across goal towards the far corner. It veers agonisingly wide however and Chelsea pass up another chance.

And here is Chelsea's final change, Hazard off for... Victor Moses? That's an odd one. In any case, Cesc Fabregas won't be making an appearance this evening.

Another change for Chelsea; Oscar comes off and Michy Batshuayi comes on for his Blues debut.

Kante loses a shoulder-to-shoulder with Payet and clips his fellow Frenchman as he bursts away from him. The Chelsea midfielder was booked inside three minutes this evening, but luckily for him, Anthony Taylor keeps his cards in his pocket.

Just under 10 minutes left in this contest.

Here's Chelsea's first change of the game; Willian is off to be replaced by Pedro. Cesc Fabregas remains on the bench.

What a finish from James Collins! West Ham scream for a handball after Payet's corner causes havoc in the box, but the big centre half keeps his cool and rifles a superb half volley into the far corner!

Goal! Chelsea 1-1 West Ham (James Collins, 76)

Payet's effort takes a nick off the wall and bounces out for a corner. Chelsea breathe a sigh of relief.

Carroll bravely challenges for a high ball on the edge of the box and is caught by the boot of Azpilicueta. West Ham have a free kick bang in the middle of Payet territory.

Adrian can't believe Costa wasn't shown a second yellow card after this. After seeing the replay, neither can we.

Oscar's cute effort hits the West Ham wall and it is cleared.

Chelsea have a great chance to double their lead here; they have another free kick about 25 yards out. Oscar and Willian stand over it.

Err, looking at the replays of that Costa challenge on Adrian, he definitely should have been shown a second yellow. It was a wild one.

His delivery is a decent one but Ivanovic gets to it first and nuts clear.

Noble now wins a free kick down the other end out on the left flank. Payet has his first chance to make in impact.

A back pass reaches Adrian and the goalkeeper tries to be a bit too fancy, inviting Costa to slide in and try to win the ball. He's caught by Costa's late challenge, but it did look like a genuine attempt to win the ball. The Chelsea striker is already booked, but no further action is taken.

West Ham need to change things quickly here and Bilic has looked towards Dimitri Payet to do so. The France international is on to replace Nordtveit.

Willian's corner is superb, right onto the noggin of John Terry but the Chelsea skipper powers his header over the bar.

Another fine save from Adrian! Hazard gets on the ball in a central position and threads a superb ball through for Willian on the right. His first touch takes it past Masuaku, opening up the room for a low drive across goal but the West Ham keeper palms it around the post.

You feel it's just a matter of time before Chelsea get a second. Oscar threatens to pick his way through coming in from the right but instead settles for a corner.

Kante gets a huge round of applause from around Stamford Bridge after winning a duel with Carroll in the middle of the park. The West Ham striker wants a free kick; he's had a frustrating game isolated up front on his own.

Hazard took eight months to score his first goal last season. He waited 47 minutes to notch his first of the 2016-17 season.

After giving away that penalty and having been led on merry dance by Hazard all evening, Michel Antonio has been pulled out of the firing line. Sam Byram is onto replace him.

Chelsea are in full control here. Nordtveit is caught in possession in the middle of the park and Matic drives forward, threading one through for Willian down the inside right. He cuts a ball back across goal but Hazard opts to take a touch before shooting, allowing Reid to get in and clear.

Hazard steps up and smashes it into the roof of the net! Chelsea lead and Hazard gets his reward; he's been the best player on the pitch.

Goal! Chelsea 1-0 West Ham (Eden Hazard, 47)

Costa is denied at the near post by Adrian and West Ham fail to clear their lines with Matic bursting into the box. Antonio steps across him in an attempt to nick the ball away from him but he clearly impedes the Chelsea midfielder and the referee points to the spot!

PENALTY - Chelsea

And West Ham get us back underway for the second half.

Half time: Chelsea 0-0 West Ham

Adrian saves! It's a very decent effort from Willian as he curls it up and over the wall but the West Ham goalkeeper follows it all the way and punches over. Azpilicueta can't get to the ball from the resulting corner and the referee blows the whistle for half time.

Costa drifts expertly across Reid after taking the ball under control but is then floored by the West Ham defender. Chelsea have a free kick from 30 yards out in what could be the last kick of the half.

Hazard again does brilliantly out on the left, nicking the ball of Collins and jinking out to the wing before pinging a cross into the box. West Ham have plenty of players back, however, and hammer it clear. Two minutes of time added on in this half.

Ayew's game is over; he's been forced off inside the first half with what appears to be a thigh problem.

Carroll wins the ball in the Chelsea half but urgently needs some help. Kouyate storms forward ahead of him but the striker looks to Tore who has popped up to his right. The former Chelsea youth player takes his eye off the ball at the wrong moment however and it rolls away from him, inviting Chelsea to come forward again.

It was Andre Ayew who was trying to keep pace with Hazard there and the new West Ham signing looks to have pulled something in his efforts to keep up. His debut unfortunately comes to an end after just 35 minutes with Gokhan Tore coming onto replace him.

Close form Hazard! The Belgium international springs into life down the left, bursting past his man as he cuts in before looking for the far corner of the net, but his effort veers just wide.

How has N'Golo Kante's Chelsea debut gone so far, you ask? Apart from the yellow card after just two minutes, not too bad.

Following that decision, Costa took it upon himself to share his grievances with Anthony Taylor. As he does. The Spain international is booked for dissent as a result.

Noble spends far too long dallying on the ball just outside the edge of his own area and Oscar robs him of the ball, breaking into the box before going down under a challenge from Winston Reid. Penalty? No, says Anthony Taylor. Oscar's hit the deck rather flamboyantly, but Reid did look to have stuck his arms out. Chelsea aren't happy.

After a few moments where Costa was unable to control the ball, Conte and Bilic show him how it's done. A long ball out from the back soars out of play and the Chelsea boss expertly cushions it into the path of Bilic, stood yards away from him in his own technical area. Good stuff.

Good save from Adrian! Ivanovic comes in from the right and turns sharply in the box, opening up the space for the shot. He looks to squeeze one in the near corner, but the West Ham goalkeeper is alive to it and palms it away.

Hazard brilliantly lures Nordtveit in over on the left and scampers away from him brilliantly, before trying to feed Costa, whose first touch lets him down. West Ham briefly get the ball back but Willian wins it again and breaks down the right. He too looks for Costa in the middle but againn his first touch is a poor one. Very rusty from the big Spaniard so far.

Kante loses out in a duel with Noble on the edge of the box, allowing the West Ham skipper to swipe an effort on goal but it is always drifting wide. It's been a good start here from both sides.

Valencia blasts one in that Matic knocks up high in the air inside his own box. Everyone's jostling to get under it, but eventually the referee blows for a Chelsea free kick with Courtois under pressure.

Gary Cahill is leaping all over Andy Carroll and West Ham have a free kick out on the left that they can swing into the box.

Masuaku's first impression of Aaron Cresswell down the left isn't quite up to scratch; he dribbles the ball straight out of play under pressure from Willian.

Yellow card for Kante! Two and a half minutes in, the new signing is booked for bringing down Carroll on the half way line. The West Ham striker was breaking ahead of him, but Chelsea had plenty over cover back. Seems a tad harsh this early in the game...

Willian whips it in but Carroll, inside the edge of his own box, gets to it first and hoofs away.

Costa picks the ball up over on the inside left channel and charges towards the West Ham defence, skipping past one challenge before Collins brings him down. Chelsea have a free kick that Willian will whip in.

And Chelsea get us started at Stamford Bridge.

Just a few minutes until kick-off, here's a reminder of the teams.

Chelsea team to face West Ham: Courtois; Ivanovic, Cahill, Terry), Azpilicueta; Kante; Willian, Matic, Oscar, Hazard; Costa

Subs: Begovic, Aina, Fabregas, Loftus-Cheek, Moses, Pedro, Batshuayi

West Ham team to face Chelsea: Adrian, Antonio, Reid, Collins, Masuaku, Nordtveit, Ayew, Noble, Kouyate, Valencia, Carroll

Subs: Randolph, Byram, Ogbonna, Oxford, Obiang, Tore, Payet

Kante is out on the pitch doing his warm-up ahead of kick-off; he starts in midfield tonight.

Andy Carroll leads the line for West Ham tonight, but he will soon have some more competition for the role. Argentina forward has Jonathan Calleri joined the Hammers, pending international clearance, and is expected to link up with his new squad next week following Argentina's elimination at the Olympics. Bilic said of the 22-year-old:

He is a top striker. Unfortunately for him, but good for us, Argentina were knocked out of the Olympics this week, so he should be here with us pretty soon, depending on the work permit.

There are three Premier League debuts in the West Ham starting XI this evening in Arthur Masuaku, Håvard Nordtveit Andre Ayew. Gökhan Töre is also on the bench, alongside Dimitri Payet. Slaven Bilic warned last week the France international may not be completely match fit for the season opener and has opted against naming him in his starting XI.

Michy Batshuayi starts on the bench for Chelsea tonight but there is a full debut for N'Golo Kante. He partners Nemanja Matic in very formidable-looking midfield.

BREAKING: Andre Ayew makes his West Ham debut this evening, as do Håvard Nordtveit and Arthur Masuaku. Dimitri Payet starts on the bench.

BREAKING: N'Golo Kante will make his Premier League debut for Chelsea this evening. He starts in midfield while Diego Costa leads the line up front.

The teams are arriving at Stamford Bridge ahead of our 8pm kick off; confirmed line-ups are expected in the next five minutes or so.

What's happening with Diego Costa, then? The prospect of a return to Atletico Madrid for the Spain international has been one of the biggest subplots at Stamford Bridge this summer, but surely we are too late into the summer transfer window for anything to happen now? Antonio Conte concurs.

I am happy that Diego stays here to work with us. We know that we can improve through the work and the most important thing is that the players have put themselves into this idea. Diego can give a lot to this team and I am sure he will have a good season.

Another West Ham signing in Arthur Masuaku is also in contention to make his debut tonight. The full-back signed from Olympiacos to fill the void at left-back created by Aaron Cresswell's serious knee injury has been cleared to play by West Ham's head of medical and sports science, Stijn Vandenbroucke, while the trio of Cheikhou Kouyate, Pedro Obiang and Darren Randolph are all available after sustaining minor knocks.

Team news: West Ham

Aaron Cresswell and Manuel Lanzini both suffered injuries during the Hammers' pre-season campaign, headaches Slaven Bilic didn't need. The West Ham boss also doesn't expect Dimitri Payet to complete 90 minutes tonight, having only recently returned to training following his summer rest.

New signings Andre Ayew, Sofiane Feghouli and Ashley Flecther are all in contention to make their league debuts. Bilic told a press conference last week:

We are still waiting to see on a couple of positions who are going to start. "Dimitri Payet is one of the players. He came back very fit. Like every player he needs a pre-season but he came back very motivated.

Team news: Chelsea

With the exception of Kurt Zouma, who remains sidelined with a long-term knee injury suffered last season, Chelsea have a clean bill of health to begin their Premier League campaign. Summer signings Michy Batshuayi and N'Golo Kante are both in line to make their competitive debuts this evening. Speaking to the press on Friday ahead of tonight's match, Antonio Conte said:

The match will be very good. They are a strong team. Last season they had a good season. They have a good manager and good, physical, fast players with great talent.

"Also it's a derby. These types of games are very tough. But we want to play and start the season. It's the first time for me for everything. To start with a derby is tough but I'm excited. It's important my players must start in the right way, to take confidence after a year last year.

Premier League football returned with a bang at the weekend and now it's time for Chelsea and West Ham United to join the party. This evening, we will get our first look at Antonio Conte's revolution at Stamford Bridge as he aims to revive the fortunes of a club who recorded their worst Premier League finish in 20 years last term.

Big things are expected from the former Juventus and Italy boss and his first test is a sizeable one against Slaven Bilic's West Ham. Last season, the Hammers thrived on their away trips to the league's big boys, picking up wins away tot Arsenal, Liverpool and Manchester City and draws at Manchester United, Leicester City and... Chelsea. Can do the same tonight? Doing so will get their top five ambitions off to a very healthy start.

Kick-off is at 8pm this evening; stick around for all your team news as it reaches us.
