Ranking Chelsea players by performance this season, with summer signing Diego Costa only 3rd

8) John Terry – Chelsea’s inspirational captain, the veteran centre-back has looked back to his very best form this season.

7) Cesar Azpilicueta – A superb performer in an unfamiliar left-back role, the Spaniard has kept summer signing Filipe Luis out of the team.

6) Branislav Ivanovic – Consistent and reliable as ever, Branislav Ivanovic remains a key player for Chelsea with his all-action displays at right-back.

5) Oscar – Needs more consistency perhaps, but there are signs that the young Brazilian is really becoming a more senior player in the Chelsea team this season.
