For his toughest test since returning to West Ham, David Moyes sticks with the three-man defence that worked so well against Gillingham.
Moyes switched to a 3-4-3 formation in the FA Cup last weekend and sticks with the formation against Sheffield United at Bramall Lane.
Ryan Fredericks is out until next month with a hamstring injury, so Pablo Zabaleta starts. Aaron Cresswell is back after missing the Gillingham game, while Arthur Masuaku also continues.
Captain Mark Noble is fit again. Lukasz Fabianski starts in goal and David Martin is back to take his place on the bench as the back-up goalkeeper.
Michail Antonio is still out with a hamstring issue so Sebastien Haller leads the line.
Jack Wilshere is still not fit and Andriy Yarmolenko is also missing because of injury.
Sheff Utd: Henderson, Basham, Egan, O'Connell, Baldock, Lundstram, Norwood, Fleck, Stevens, McGoldrick, McBurnie
Subs: Sharp, Robinson, Jagielka, Mousset, Osborn, Besic, Eastwood
West Ham: Fabianski, Zabaleta, Balbuena, Ogbonna, Cresswell, Lanzini, Noble, Rice, Masuaku, Felipe Anderson, Haller
