David Moyes has made four changes for today's FA Cup fourth-round tie against West Bromwich Albion, with Swiss striker Albian Ajeti given his third start since joining the club last summer.
Carlos Sanchez also starts in midfield while Pablo Fornals and centre back Fabian Balbuena also come into the team following Wednesday night's comprehensive defeat away to Leicester City.
Moyes had said he was keen to get a look at Ajeti, who has only featured off the bench in the Premier League having started both Carabao Cup games at the beginning of the season.
Sanchez, meanwhile, is making his first start since Manuel Pellegrini's final game in charge at the end of December. He will partner Declan Rice as the holding midfielders in a 4-2-2-2 that sees Ajeti partner Sebastien Haller up front.
The Scot has paired Balbuena with Issa Diop while Aaron Cresswell is moved across to left back after he starting as a centre half at Leicester.
Arthur Masuaku and Robert Snodgrass are both out of this meeting with former manager Slaven Bilic because of knee injuries, while Angelo Ogbonna has been carrying a back issue but is fit enough for a place on the bench.
Bilic has made wholesale changes with the Baggies looking to seal promotion from the Championship. They face Cardiff on Tuesday evening, 24 hours before West Ham host runaway leaders Liverpool in E20.
