Diego Costa made it seven goals in four Premier League outings as his hat-trick helped Chelsea to record a 4-2 victory over Swansea City at Stamford Bridge this afternoon.

The Spaniard's three goals arrived after Chelsea captain John Terry had bundled the ball into his own net, before debutant Loic Remy made it 4-1 to the hosts.

Jonjo Shelvey pulled a goal back for the visitors late on, but it was an afternoon that had been dominated by Costa.

Here, Sports Mole has looked back on the performances of each of the players that featured in West London.

CHELSEA

Goal

Thibaut Courtois: There wasn't too much for the Belgian to do today, while there was little that he could have done to prevent either of the Swansea goals. (6/10)

Defence

Branislav Ivanovic: The right-back has set such a high standard this season that it is noticeable when he dips below it. That was the case today because the Serbian was not at his attacking best. (6/10)

John Terry: It wasn't Terry's best performance, that's for sure. The skipper scored an own goal and looked a little shaky at times. (6/10)

Gary Cahill: Like Terry, it wasn't a display that Cahill will be overly pleased with. He went missing for Swansea's second goal and will no doubt be looking to move on as quickly as possible. (6/10)

Cesar Azpilicueta: A lot of the talk heading into this encounter was about the form of Swansea winger Dyer, but he was nullified by a very good defensive showing from Azpilicueta. (7/10)

Midfield

Cesc Fabregas: There are not enough superlatives to describe the midfielder, who turned out yet another great performance. The assist for Costa's second goal was his sixth of the season already. (8/10)

Nemanja Matic: The Serbian will not get many headlines this season because there are much more flamboyant players in the Chelsea side, but he often does his job well and he did today. It was a steady showing from the holding midfielder. (6/10)

Eden Hazard: After a quiet opening 30 minutes or so, Hazard came to life and produced what was arguably his best performance of the season so far. He went on plenty of runs with the ball at his feet and drew numerous fouls. (8/10)

Oscar: He hasn't quite clicked into gear this season. That's not to say that he was poor, because he was neat and tidy in possession, but you expect more from a player of Oscar's talent. (6/10)

Andre Schurrle: He was hauled off after 45 minutes and when you consider his performance, it's easy to understand why. Schurrle may find it difficult to get back into the side for a while after this. (5/10)

Attack

Diego Costa: Already a hero among the Chelsea faithful before today, the Spaniard is now held in even higher esteem thanks to his hat-trick. There was nothing flashy about any of his goals, they were just pure striker's instinct and that's what the Blues were missing last term. (9/10)

Substitutes

Ramires: The Brazilian replaced Schurrle at the break and it was his presence that freed up the likes of Fabregas to get further forward. All in all, he did his job well. (6/10)

Loic Remy: There will have been some pressure on Remy, replacing the hat-trick hero, but he shouldered that well. His goal came from a very composed finish, while he also showed that his pace will provide Chelsea with another option in the final third. (7/10)

Mohamed Salah: The winger is believed to be frustrated with a lack of action and didn't get much time today. He did look lively, but the game was well over by the time that he entered the action. (6/10)

SWANSEA

Goal

Lukasz Fabianski: The former Arsenal keeper appears to be thriving on being the number one at Swansea. He made a couple of good saves and despite conceding four goals, he cannot really be faulted. (7/10)

Defence

Angel Rangel: It was a quiet outing from Rangel, who usually gets forward well. The threat of Chelsea's attackers was probably behind that, but it did hamper his overall display. (6/10)

Ashley Williams: As captain, Williams did his best to rally the troops when Costa started to prosper. On a personal level, he will probably be bitterly disappointed that a centre-forward was allowed to score a hat-trick on his watch. (6/10)

Jordi Amat: The centre-back was booked for a late challenge on Hazard and was lucky not to pick up a second caution following tussles with Costa. It came as little surprise when he was substituted. (5/10)

Neil Taylor: During the first half, the Welsh full-back was a real outlet for Swansea down the left. It was his cross that Terry sent into his own net, while defensively he did well. (7/10)

Midfield

Ki Sung-Yueng: When Swansea were on top during the first half, virtually all of their moves were started by Ki, who would collect the ball from one of his own defenders, before spraying passes. His influence waned in the second half. (7/10)

Jonjo Shelvey: The former Liverpool man showed good composure when he scored late on, but he will have been operating too deep for his liking. (6/10)

Gylfi Sigurdsson: Upon his return to Swansea, Sigurdsson has been one of the Premier League's best players this term. That form deserted him today, though. It was a quiet afternoon as far as the Iceland international was concerned. (6/10)

Nathan Dyer: Similar to Sigurdsson really in that he struggled to bring his recent positive form into the game. The winger did start in lively fashion, but faded. (6/10)

Wayne Routledge: The winger started well and went close with two shots from the edge of the area early on, but after that he struggled to make an impact and was later substituted. (6/10)

Attack

Bafetimbi Gomis: It was his first Premier League start for the Swans and the Frenchman should some bright moments. He's not afraid to have a shot and was happy to get involved in the physical battles with Terry and Cahill. (7/10)

Substitutes

Federico Fernandez: He replaced Amat and can count himself unfortunate that he ran into Costa in such good form. Having said that, he didn't do anything glaringly wrong. (6/10)

Jefferson Montero: The summer signing came on in the 66th minute, but such was Chelsea's dominance, he didn't have any real opportunities to show his pace and direct style. (6/10)

Wilfried Bony: The Ivory Coast international was late back from international duty, which was the reason behind him starting on the bench. By the time that he came on, the game was over and he had little impact. (6/10)
