Jordan Henderson, Divock Origi and Danny Ings will not feature but could all return from injuries before the end of the season.
Watford could be unchanged after beating Aston Villa last weekend.
Allan Nyom and Nathan Ake are pushing for recalls but Etienne Capoue remains sidelined with a knee injury.
