Follow Daily Mail Sport's live blog for the latest score, team news and updates as West Ham welcome Chelsea to the London stadium in Premier League action, with Kieran Gill and James Sharpe reporting from the ground.
Joao Pedro and Liam Delap both start for Chelsea, one on the left wing and the other up front, which is a slight surprise. Tosin Adarabioyo has immediately come into the defence after missing last week's 0-0 draw with Crystal Palace due to a niggle. No surprise there, as Enzo Maresca trusts him more than Josh Acheampong.
