Chelsea are off to a poor start against West Ham at the London Stadium.
A well-taken finish from Marko Arnautovic gave Thibaut Courtois no chance.
Cesar Azpilicueta gave the winger too much room to manoeuvre as Arnautovic made no mistake.
The Blues can’t afford more mistakes like this for the rest of the match.
So the Hammers have the shock lead just five minutes in.
Here is West Ham’s goal:
