Crystal Palace 0-3 Chelsea: Player Ratings as Brilliant Costa Helps Blues Get Their Groove Back

​Chelsea produced their greatest performance of the season in comfortably seeing off Alan Pardew's Crystal Palace 3-0 at Selhurst Park. 

Goals from Oscar, Willian and Diego Costa catapulted Guus Hiddink's men to well-deserved three points and lays the groundwork for a potential resurgence. 

Here are the player ratings. 

6. Palace Defence

Wayne Hennessey - 5

The Welsh goalkeeper was forced to make some smart saves but he was at fault for the third goal when he should have dealt with Willian's shot more convincingly. 

Joel Ward - 5

Was caught napping at times by Chelsea's attack and was unable to stop Costa scoring the third. 

Scott Dann - 5

Kept going right until the end but struggled against an in-form Costa and Willian who seemed to be everywhere. 

Damien Delaney - 4

The veteran defender had Costa in his back pocket at Stamford Bridge but he was unable to emulate such a performance and struggled badly here, failing to intercept Fabregas' pass for the first goal. 

Cedric Souare - 5

Went missing for the second and third goals, which both came from down his side. ​

5. Palace Midfield

James McArthur - 5

Was unnerved by Fabregas towards the end of the game but it was telling as the midfielder had not performed well. 

Mile Jedinak - 5

Made a number of fouls and poor decisions before being taken off in the 67th minute. Looked off the pace. 

Jason Puncheon - 5

The attacker had spoken about filling the shoes of Cabaye and Bolasie but he went missing went Palace really needed him and had no influence in the game. 

Chung-Yong Lee - 5

The South Korean international featured early on in the game and tried to use his pace to trouble Ivanovic, but faded as Chelsea began to dominate. 

Wilfried Zaha - 6

The only Palace player who looked capable of doing anything, kept going right until the end and showed some good skill at times. Still needs to be more consistent with his end product. 

4. Palace Attack

Frazier Campbell - 5

Thanks to the vigilance of Mikel and a rock-solid Zouma/Terry partnership, Campbell wasn't able to get himself into the game at all and was thoroughly marked until he was subbed off. 

Marouane Chamakh - 5

Came on and tried to do what Campbell was unable to but failed, much to the frustration of the crowd. His and Campbell's woes highlighted the need for a striker in January for Pardew. 

Joe Ledley - 6

Came on but didn't really influence the game or restore balance to the Palace side. 

3. Chelsea Defence

Thibaut Courtois - 6

Was barely troubled all afternoon but handled any aerial situation with consummate competence and ease and kept a clean sheet. 

Branislav Ivanovic - 6

Hasn't performed well this season but the Serbian looked back to his normal self, making plenty of willing runs down the flank and defending solidly. 

Kurt Zouma - 7

Missed a great chance with a header but, defensively speaking, he was flawless. 

John Terry - 8

Used all his experience and nous to command the back-line brilliantly and managed to keep Chelsea in control throughout the entire game. 

Cesar Azpilicueta - 6

Missed a presentable opportunity when the game was still at 1-0 but played well compared to some displays this season. 

2. Chelsea Midfield

John Obi Mikel - 9

Absolutely bossed the midfield area in one of his finest ever performances. Sometimes criticised, but Mikel's contribution to this game did not go unnoticed by the Chelsea fans, who were chanting his name at the end. 

Cesc Fabregas - 7

One of the most heavily criticised players this season, the Spaniard was at the heart of their creativity once again and showed his excellent vision with the pass that set up the opener. 

Oscar - 7

Contributed well with the first goal, redeeming himself for a couple of wobbly performances recently and the horrendous penalty miss against Watford on Boxing Day. 

Willian - 8

Another outstanding performance from the Brazilian, who scored a screamer and set up Costa as he spearheaded the Chelsea resurgence. 

Eden Hazard - N/A

Went off with a nasty injury after 15 minutes. 

1. Chelsea Attack

Diego Costa - 8

The Spaniard was back to his best here, refusing to be drawn in to silly squabbles and showing his quality instead. Was selfless in setting up Oscar for the first when he could have shot himself and got the goal he deserved at the end. 

Pedro - 6

Came on and showed a great change of pace on a number of occasions, but still needs to refine his end product. 

Nemanja Matic - 6

Came on and added some energy to the midfield.
