Player Ratings-Chelsea vs Westbrom

Thibaut Courtois: The Chelsea goalkeeper made an early impact when he saved Morrison's penalty and then showed his commanding presence to collect numerous crosses as the match wore on. (7/10)

Defence
Branislav Ivanovic: The Serbian once again looked a yard off the pace as he struggled to deal with the threat of West Brom's wide players. (4/10)
John Terry: Before he was sent off, Terry responded to being substituted last week with a solid display. But, the red card came as a result of his lack of pace, which is exactly why he was replaced seven days ago. (6/10)
Kurt Zouma: Introduced into the side at the expense of Cahill, the young Frenchman did little wrong. (6/10)
Cesar Azpilicueta: While the Spaniard will have been delighted to have scored his first ever Premier League goal, like Ivanovic, it was by no means his best performance defensively once again. (5/10)
Midfield
Nemanja Matic: Once a player that seemed to boss midfield battles with ease, Matic struggled today. Whereas before he ran proceedings, there were times when he left the back four exposed. (5/10)
Cesc Fabregas: Usually such a creative force, Fabregas gave away possession more times than any other player on the pitch. (5/10)
Willian: He may have been neat and tidy in possession once again, but his performance will be best remembered for the glaring chance that he missed towards the end of the first half. He was substituted after the restart following Terry's red card. (6/10)
Pedro: Within 30 minutes, the signing from Barcelona looked a snip at £21m. He opened the scoring, before setting up Costa for his goal. Aside from that, he offered more dynamism to the Chelsea attack before he was replaced looking a little tired in the closing stages. (8/10)
Eden Hazard: Still some way from his very best, there was at least the odd sign from Hazard that he is not too far away from rediscovering some decent form. He carried the ball well on occasions, although his finishing was poor. (6/10)
Attack
Diego Costa: Last season's leading goalscorer was too interested in fighting last week at the Etihad Stadium, but he let his football do the talking today. He scored an opportunistic goal, while his hold-up play was also really good. (7/10)
Substitutes
Gary Cahill: There were a couple of nervy moments for the masked defender after he came on to fill Terry's absence, but he helped to keep West Brom out in the closing stages. (6/10)
Radamel Falcao: There was one good chance for the Colombian, but not for the first time since he's been in England, he scuffed it wide. (5/10)
John Obi Mikel: The Nigerian came on with only a few minutes left to help protect the lead. (5/10)
