I'm gonna hazard a guess: Luis and Stevie starts on the bench.
Can see us fielding something like:
Reina
Kelly - Carra - Skrtel(Agger if fit) - Enrique
Kuyt - Henderson - Lucas - Adam - Downing
Carroll
Luis and Stevie coming on early in second, replacing Hendo and Downing/Kuyt, tearing up a worn down United-defence. Johnson in for Kelly around 70, supposing no forced subs before that.
