Wayne Rooney and Phil Jones (both ankle) and Rio Ferdinand (back) are all giving Ferguson a selection headache with all needing late tests.
Nani is expected to miss the game with his foot injury, although that is just what the papers have to say, nothing official has come from the club.
Provisional squad: De Gea, Lindegaard, Amos, Smalling, Rafael, Ferdinand, Evra, Jones, Evans, Fabio, Fryers, Cole, Carrick, Scholes, Valencia, Park, Nani, Giggs, Rooney, Welbeck, Berbatov, Hernandez, Diouf.
