Graham Potter has made three changes from the draw against Fulham last time out.
West Ham vs Chelsea line-ups
Joao Felix returns to the team having missed three games through suspension, and is joined by Noni Madueke and Ruben Loftus-Cheek as the players coming in.
Hakim Ziyech, Conor Gallagher and Mason Mount are the players making way.
There are starts again for recent signings Enzo Fernandez and Mykhailo Mudryk. The defence that kept a clean sheet last time out is unchanged.
Raheem Sterling misses out today due to a knock in training.
West Ham defender Thilo Kehrer has overcome a hamstring strain so David Moyes is able to name the same side that drew at Newcastle. Former Blue Emerson Palmieri plays.
