Chelsea don't like making things easy, and this season they appear to be making it harder than ever. Thomas Tuchel's side went 1-0 down following some poor defending and nearly gave up their lead with another late mistake.
Reece James' poor header allowed the Hammers back in and when a collision with Jarrod Bowen left Edouard Mendy on the floor in pain, Maxwel Cornet put the ball in the goal and sent the away fans into delirium. VAR intervened and broke their hearts when Chelsea were awarded a free-kick and sigh of relief was sent around Stamford Bridge.
Chelsea's substitutes made the difference as Ben Chilwell first provided some ingenuity to record an equaliser for the Blues before turning provider for Kai Havertz's winner. The German forward will be almost as relieved to record his first goal of the season as earning Chelsea three points late on.
