Chelsea inflicted Swansea City's heaviest Premier League defeat when they won 5-0 at the Liberty Stadium in January 2015 and, although this game is only a little over 20 minutes old, another thrashing could be on the cards.Swansea's pragmatic 5-4-1 formation does not look fit to contain this rampant Chelsea side, let alone pose any threats to them.
Swansea 0-1 Chelsea
Francesco Guidolin is down on his haunches, swaying from side to side as he looks for a way to weather this Chelsea storm. Before the goal Swansea were doing OK, they had 60% of the early possession.
Then Chelsea showed up.

Swansea look in trouble. they have to re-adjust and get back into their positions. Chelsea look very dangerous with Oscar, Eden Hazard and Diego Costa, who scored.
I haven't heard it this flat at the Liberty Stadium for some time.

Chelsea have found their form from the autumn of 2014. They are ripping through Swansea at will now as Eden Hazard again breezes away on the left and finds Oscar in the D - his shot is tipped away. Branislav Ivanovic tries a backheel from the corner and it's just about scrambled away.

It was an excellent finish from Diego Costa, but the defence handed him that chance on a plate.
Eden Hazard then drives past Kyle Naughton and he's in on goal, Lukasz Fabianski makes a good save though to turn it over the top.
Swansea in trouble...
Diego Costa
A catalogue of errors in the Swansea backline lead - almost inevitably - to a Chelsea opener.
Federico Fernandez initially meets a cross well, but he can only head it straight up in the air. A steepler to long-on, Lukasz Fabianski starts to come for it but Fernandez then decides to head it - straight to Oscar.
Oscar squares it to Diego Costa, who buries it from 16 yards.

Shoddy from Eden Hazard, who gives the ball away with an unnecessary flick and Ki Sung-yueng is fouled by Cesar Azplicueta. Swansea free-kick out wide is whipped in by Gylfi Sigurdsson - and it goes right through the goalmouth.
Where was the poacher?

N'Golo Kante appears to have settled in to the Chelsea midfield like he did at Leicester last year. He's always in the right place to make a tackle, as he does on Neil Taylor after Fernando Llorente had played the wing-back in down the line.
Swansea 0-0 Chelsea
Branislav Ivanovic is roaming up and down the right flank, more attacking than he has often been in seasons past perhaps, and he wins a free-kick in a good area. Willian's delivery is classy as ever and Ivanovic is there to head over.
Swansea 0-0 Chelsea
Willian gets all sorts of serve into his shot from 25 yards but Lukasz Fabianski can only push it nervously away. John Terry gets to the corner first but can't make anything of it.
First shot on target.

The phrase "prowling the touchline" could have been coined for Antonio Conte, who looks menacingly suave in his slim-cut black suit.
The Chelsea manager is showing up his compatriot and opposite number Francesco Guidolin, whose tracksuit and trainers give the impression of someone who has just been out for a Sunday afternoon stroll with their dog.
Swansea 0-0 Chelsea
Stephen Kingsley is playing on the left of Swansea's back three, with Neil Taylor at wing-back. I expected them to be the other way round. Swansea have made a decent start as they force Chelsea to defend strongly and clear two early crosses. Fernando Llorente the target.

How will the Swans adapt to a back three? I often wonder if fans and the media sometimes overplay the extent of difficulty for players to switch formations. Remember when Steve McClaren played three at the back for England? Meltdown.
Diego Costa takes a whack in the back early on.

The players are in the tunnel, and here they come. Chelsea in all black today, will we see a dominant display?

Chelsea manager Antonio Conte speaking to Sky Sports: "I know him (Swansea boss Francesco Guidolin). He is a good manager and he knows tactics very well.
"I think this game Swansea will play a defensive game and on the counter-attack. For us it is a very tough match."

Chelsea have named an unchanged team in the Premier League for the first time since February, and it's the first chance I've had to see them properly in action.
Once I get over the fact that N'Golo Kante is wearing the number seven I'll be intrigued to see how they get on.
The result of the vote for August's goal of the month in the Premier League from a shortlist of eight.
