The 2-1 defeat by Chelsea at Stamford Bridge on Monday was West Ham's fourth defeat in their past six Premier League games - as many as in their prior 13 games in the competition.
But head coach Graham Potter will hope the return of Jarrod Bowen will help turn the fortunes around for the struggling Hammers.
Bowen, who made his first appearance after fracturing his foot in a 5-0 home defeat to leaders Liverpool on 29 December, marked his return with a goal that pulled his side ahead in the first half.
