Chelsea have become the first club in Premier League history to go on run of nine-game winning run on five separate occasions.
Antonio Conte’s side have been in red-hot form since their switch to a 3-4-3 system at the start of October.
And Diego Costa’s second-half strike sealed a narrow 1-0 victory over West Brom on Sunday sealed Chelsea’s ninth consecutive victory in the Premier League.
Before the match, Chelsea had been level with Manchester United as both clubs had gone on a 9+ winning run in the division on four occasions.
