Swansea City 2-2 Chelsea: Premier League as it happened

That's that. A breathless second-half comes to an end and Chelsea have dropped points for the first time under Antonio Conte.

Full time: Swansea City 2-2 Chelsea

Ki now goes down in the box following the slightest nudge from Fabregas. The Liberty Stadium screams for a penalty, but Andre Marriner is having none of it.

Hazard loses possession again and Fer pounces again. He drives forward a couple of yards and drops a shoulder to beat Terry, who shoves him to the ground to stop the move. That will be a booking for him, too.

Four minutes of time added to this breathless second half.

There have been so many mistakes in this game; it's been brilliant. Hazard is now the guilty man, losing the ball in the Swansea half and inviting Fer to burst upfield. The Belgian can keep up with him however and tugs him back, accepting his inevitable booking.

There will be a change for either side as we head into the final minutes of the contest. Michy Batshuayi comes on for Oscar while Angel Rangel replaces Sigurdsson.

Chelsea's defending is still all over the shop and only a desperate last minute challenge from Cahill prevents Swansea from getting a shot away in the six yard area.

Another fine save from Fabianski! Chelsea swarm forward and Hazard shifts the ball to his right for Costa, who hammers one towards the near corner. The Swansea goalkeeper stands up to it, however, beating his effort away.

Could Swansea have had a case for appealing for a high boot there?

Chelsea are level! After a neat passing move around the box, Ivanovic brilliantly darts in from the right, beating his man before lashing a shot on goal. It's blocked and knocked high into the air, but Diego Costa meets it with a vicious bicycle kick.

Goal! Swansea City 2-2 Chelsea (Diego Costa, 80)

Half a chance for Oscar. The Brazilian looks just offside, but a pass squirms its way through to him on the edge of the box. He has time to take a touch and set himself, but drags a tame effort wide of Fabianksi's goal.

And here come the changes, Cesc Fabregas replaced Matic while Victor Moses comes on for Willian.

Kyle Naughton makes a terrific defensive header to clear Hazard's dinked cross and is left in a heap for his trouble.

It looks like Cesc Fabregas is the man being summoned to come on for Chelsea.

Willian is fouled about 35 yards out from goal and he stands over the free kick. His dinked effort is partially cleared and Oscar's follow up effort is also booted clear.

There's been some terrible defending in this game but great entertainment. And David Luiz isn't even on the pitch! Just under 20 minutes of this contest left, Conte might start thinking about changes shortly.

The moment Courtois brought Sigurdsson down and this game was turned on its head.

Well, this game is bonkers. Suddenly Hazard races through with Fabianksi rushing out to close him down but he Belgian appears to pull out of his run with the Polish goalkeeper bearing down on him. Fabianksi sticks out a foot to intercept but it then breaks to Costa, and the Swansea goalkeeper goes after him too! There is slight contact between the goalkeeper and the striker and Costa goes down outside of the area. There are appeals for a penalty, but the referee waves them away.

Oh dear. It looked like Fer fouled Cahill at least twice there, Swansea get the rub of the green.

Incredible! From a goal behind, Swansea have scored twice in two minutes to take the lead! Under no pressure, Terry passes across to his centre-half partner Cahill who dawdles on the ball and miscontrols it, allowing the Dutchman to race through. Cahill sticks to him but Fer just about manages to sneak an effort under Courtois that crawls across the line.

Goal! Swansea City 1-1 Chelsea (Gylfi Sigurdsson, 59)

Swansea have a penalty! Sigurdsson chases down a fine long ball down the pitch from Barrow that has Courtois scampering out to get. The Blues goalkeeper isn't quick enough and he takes down Sigurdsson who gets there just before him. Courtois booked.

PENALTY - Swansea City

It;s all getting a bit heated down there. Amat, already on a yellow card, arrives late on Ivanovic. He could be in trouble here...

Now Costa will trot back on the pitch. Boos reign down from Swansea fans who weren't convinced of his injury.

Jordi Amat is now shown a yellow card for jumping into the back of Costa. The Chelsea striker rolls about a bit and stays down. He'll trot off for some treatment, looking a bit woozy.

Chelsea have come out on the front foot. Costa brilliantly shimmies away from Fer before shifting the ball wide to Hazard. He lays it off to Willian who cuts inside onto his left foot and tries to arrow one into the far corner, but it veers just wide.

And Chelsea get us back underway for the second half.

Half-time: Swansea 0-1 Chelsea

Taylor wasn't taken off because of an injury, by the way. He is raging after being hooked off by Guidolin, who looks to have shifted to a 4-3-3 formation.

What a chance for Costa to get a second! A corner comes in that Terry knocks down to the striker but he horribly miss hits his effort, prodding it across the goal rather than on target.

Diego Costa and Federico Fernandez are both booked in quick succession as we enter the final five minutes of the half. There's also a change for Swansea with Moudou Barrow coming on for Neil Taylor.

Swansea have had a great last few minutes and it;s all thanks to Sigurdsson. After delivering a couple of dangerous balls into the box, the Iceland international opts to take on a shot from range, bending one wickedly towards the far corner that just creeps the wrong side of the post.

Azpilicueta darts down the left and is brilliantly picked out by Matic. He carries on his run down the byline and has options in the box, but instead tries to beat Fabianski on his own from an impossible angle. The Swansea goalkeeper saves, and the Spaniard offers an apology to his teammates for not passing. Chelsea settle for a corner.

Oscar, in the space of two minutes, makes two fine interceptions to halt a couple of Swansea moves. It's easy to see why he's an automatic starter for Conte.

Fer's already committed a number of fouls and now he's been shown a yellow card for a rather cynical one on Costa, who was threatening to break over the half way line.

Costa's opener has given Chelsea a deserved lead.

Kante demonstrates why he doesn't take on too many shots from rage, smashing a cut back from Willian wildly over the bar. Chelsea are cruising at the moment, however.

Chelsea almost snatch a second! Hazard bursts down the left blank, easily beating his man before driving into the box to shoot but Fabianski gets down quickly and produces a decent save.

Swansea's brittle defence is exposed again. A cross from Ivanovic in from the right is headed straight up rather than out. Fabianksi thinks about coming out but then retreats, with Kingsley losing out to Oscar who does well to take the ball down and prod it across goal. He rolls it straight into the path of Costa who produces a crisp finish, placing it in the far corner out of Fabianski's reach.

Goal! Swansea 0-1 Chelsea (Diego Costa, 17)

Sigurdsson whips a brilliant ball in that bounces between Courtois and the huddle of black and white shirts perched on the edge of the six yard area. All it needed was a Swansea player to gamble and run onto it, but instead it rolls out of play.

Swansea now have the chance to get the ball into the box after Azpilicueta wrestles Sigurdsson to the ground.

Down the other end, Willian takes on Neil Taylor down the right, dancing inside the box before cutting a dangerous ball across goal that takes a slight deflection on its way. Diego Costa is lurking, but Fabianski is down quickly to gather.

Swansea now are enjoying the greater share of possession but when they get it into wide positions, they haven't been able to find the right ball into the box. Sigurdsson has a couple of efforts to try and probe his way through the middle, but Chelsea stand strong.

Fer this time clips Ivanovic and Chelsea have the chance to chuck a free kick into the Swansea box. Willian clips it in but Ivanovic's header is well off target.

Willian has the first shot on goal of the game, getting the ball off Kante who robbed Cork of possession inside his own half. The Brazilian's shot is a vicious one, but Fabianski can comfortably bat it away. Nothing comes from the corner.

Another late challenge from a Swansea player; this time Leroy Fer clips John Terry as he slides across in an attempt to intercept a risky ball across the box from Ivanovic.

A poor first touch from Kingsley allows Willian to scamper onto a loose ball but the Brazilian is clattered into by the Scot. It's been a fairly even start to this contest, neither side has really got on the front foot yet.

And Swansea get us started.

How quickly will Swansea pick up the new system their manager has implemented today? After fielding a 4-4-2 in his opening three games, Francesco Guidolin opts for a 5-4-1 with three centre halves and a midfield diamond today.

Just minutes until kick off at the Liberty Stadium, both teams are making their way out from the tunnel.

David Luiz is straight into the Chelsea squad following his deadline day return to the club.

Why change a winning formula? Antonio Conte has kept to the same team that eased to a 3-0 win over Burnley before the international break. That means the returning David Luiz settles for a spot on the bench alongside fellow deadline day signing Marcos Alonso. Michy Batshuayi, who has three goals to his name this season already, also missed out on a starting spot.

Francesco Guidolin has opted to make two changes this afternoon. Bringing in record signing Borja Baston isn't one of them, however - the Spaniard doesn't make the squad despite having returned to training following a thigh problem.

Wales left-back Neil Taylor and South Korea midfielder Ki Sung-yueng do come in however and it looks like the Swansea boss has opted for a tactical shift too, opting for a 5-4-1 with a diamond in midfield over his usual 4-4-2.

BREAKING: There will be no debut for Borja Baston today, he isn't even in the squad. Fernando Llorente leads the attack for Swansea.

BREAKING: Antonio Conte names an unchanged side for this afternoon's game. Marcos Alonso and David Luiz start on the bench.

What about Chelsea's other deadline say signing? Marcos Alonso returned for his third spell in the Premier League on deadline day and the arrival of the left-back could finally see Cesar Azpilicueta moved to his natural position on the right hand side of defence. Conte said of Alonso:

It was important to bring in Alonso because he is left-footed – in the squad we have three [full-backs] who are right-footed. He's played in England before and for this reason he has good experience of this league.

Borja Baston joined his countryman Fernando Llorente at the Liberty Stadiun this summer. The forward, who arrived from Atletico Madrid for a reported £15m, has been unable to make his debut due to a thigh injury suffered in training, but having stepped up his return during the international break, he could have a role to play today. Swansea boss Francesco Guidolin told reporters on Thursday:

He is working, but he has to go slow (in training) for two or three days. He does not have an injury. I hope to have him available for the bench on Sunday, but I don't know. I am not sure at the moment. He worked with us last week but he needs some days where he works slowly. He is almost ready to play.

Under former interim Chelsea boss Rafa Benitez, then under Jose Mourinho and even for a brief spell while at Paris Saint-Germain, David Luiz played as a midfielder. Will Antonio Conte follow suit? That wouldn't appear to be the plan.

We needed a centre-back. In this squad we have Gary Cahill and John Terry and sometimes we can adapt Branislav Ivanovic but we need a centre-back, for this reason we got him. Sometimes he plays as a midfielder but that is not the idea for us.

David Luiz's return to west London was the story of transfer deadline day. But his move back to the capital prompted one or two questions. Will Antonio Conte have to change his formation? Will the Brazilian be picked ahead of Gary Cahill and John Terry? We considered the Italian's options.

Team news: Swansea City

In addition to Baston, Alfie Mawson may also make his debut against Chelsea after he was signed from Barnsley in the final days of the transfer window. Neil Taylor is also available for selection once again.

Team news: Chelsea
Marcos Alonso and David Luiz are both in contention to make their Chelsea debuts – in Luiz's case, his second debut – for the club this afternoon. Kurt Zouma is still not ready to return, but otherwise, Antonio Conte has all of his squad options available.

Things haven't started too badly for Antonio Conte at Stamford Bridge. Under the Italian, the Blues have taken three wins from three after victories over West Ham United, Watford and Burnley.

It took them until mid-October to surpass the nine point mark last season. But things have been far smoother this time around and already under the Italian's guidance, Chelsea look ready to mix it up at the summit of the Premier League again. Victory today will see them move level on points with Manchester City, who broke away from rivals Manchester United's after Saturday's derby success at Old Trafford.

After a promising victory over Burnley on the opening day of the season, Swansea have faltered. Defeats to Hull and Leicester see them sat in 16th place, but with record signing Borja Baston in contention to finally make his debut for the club, there could be reason for hope today.
