Diego Costa is the striker that just keeps giving - his three goals that downed plucky Swansea City at Stamford Bridge was his seventh in four league games.
Chelsea's second transfer window signing Loic Remy hit his first Blues' goal on his debut as he came off the bench to notch Chelsea's fourth as they stay top of the Premier League having won all of their opening league matches.
Costa goes from strength to strength at SW6 - he has now scored seven goals in four games since his move from Athletic Madrid.
A lively start from both sides saw Diego Costa' force a save from ex-Arsenal stopper Lukasz Fabianski on two minutes while a minute later, an unmarked Wayne Routledge produced a sizzling left-footer that zipped in he's over Thibaut Courtois's crossbar.
The end-to-end flow of the game saw Swansea, on 11 minutes, produce a quick counter-attack and they fed the ball to Neil Taylor wide on the left.
The full-back put a perfect curling left-footer which beat Branislav Ivanovic, who was slightly out of position. Before he had time to react properly, John Terry stuck out his right boot and planted the ball into the back of his own net for an own goal.
Bafetimbi Gomis and Wayne Routledge had glorious chances to double their lead as Chelsea simply failed to get hold of the ball. But both times they failed to hit the target.
Terry attempted to rectify for his own goal by glancing a header just over Fabianski's goal from a clipped Cesc Fabregas free-kick.
Andre Schurrle forced the Swansea goalkeeper into tipping his 20-yard free-kick over the bat for a corner as the Blues forced their way back into the game.
Eden Hazard twice being chopped down by Jordi Amat and Jonjo Shelvely respectively - both Swans earned a yellow card from referee Kevin Friend for their efforts.
The Blues now in the ascendency got their reward with seconds of the half remaining.
After an excellent, quick passing move, the ball was cleared by Routledge for a corner. Up stepped Fabregas to send in a lofted cross that was met fully on the meat of Diego Costa's head and the Brazil-born Spain striker's effort sailed past the helpless Fabianski and into the net?
That was Costa's fifth goal in four games - which equalled the sum total by Fernando Torres last season.
Both managers made changes, Jose Mourinho replaced Schurrle with Ramires, while Garry Monk, mindful that Amat had already being booked took him off for Federico Fernandez.
If the Blues had started the match sluggishly, yet started the second like a train out of the station, forcing the Swans in desperate rearguard action, which odd see the third visitor enter Friend's book - Neil Taylor for hacking down Oscar.
The inevitable came 11 minutes after the start and a sensational goal it was. Fabregas and Hazard torn the Swans defence apart with precision one-touch football that ended up with the Ex-Barcelona and Arsenal man on the byline and he cut the ball back to Costa who was Johnny on the spot to lash the ball into the net from six yards.
A speculative thunderous 25-yard shot by Shelvey, on 62 minutes whipped past Courtois's net and daisy-cutter that got a slight deflection by Gomis failed to beat Chelsea 's goalkeeper.
But a minute later on 64 minutes, Gomis beat a static Chelsea defence and raced clear on goal. With Ivanovic breathing down his neck, the ex-Lyon French striker chipped the ball over Courtois, but there was spin on the ball and it inched wide of goal.
Any sense that the visitors would get back into the game was snuffed out 60 seconds later with Chelsea's third goal.
It was that man Costa again, who ghosted through the Swans defence and slotted home a deft left-footer from a defence-splitting pass from Ramires.
Jose Mourinho's side were now in full flight and twice should have extended their lead through Ivanovic and a cheeky back-flick by Oscar.
Mourinho, with Wednesday's Champions League encounter with Schalke in mind decided to replace Costa with 18 minutes of the half remaining. The striker left the field to a heroes reception from the 41, 400 crowd to be replaced by French striker Loic Remy, making his Chelsea bow following his January move from QPR.
The £10.5million man did not take long to open his Blues' account, latching onto a square pass from Fabregas after Hazard had run the Swans defence ragged with a 50-yard run. Remy stroked the ball home from just inside the visitors area, and past a despairing dive from Fabianski to make it 4-1 to the home side.
It's just as well Chelsea are a goal-machine of late - having put six past Everton in their last game as they went to sleep with three minutes to go allowing Shelvely to cut past Terry and Gary Cahill and plant a fine right-footer past Courtois to half the deficit.
But that was it as far as goals are concerned.
