So it looks like it's 3-5-2 at the moment..
Keeper
Why everyone wants Valdes in goal I can understand, I'd like to see him in a united shirt but its the worst sort of game for him for two reasons, if he does well, it was expected, if he does badly against a lesser team, it will look bad.Secondly, his attributes don't fit the opposition, he can go missing positionally and likes to come out and the long balls will cause him problems with our defense so I'd stick with DDG.
Defense
I would like to have Smalling due to his frame, but if he and Evans are out, I'd opt for Jones, Rojo and McNair.
Midfield
For wingbacks, it picks itself, Shaw and Rafa if fit, Valencia and Young if not, in the middle I want Fellaini for obvious reasons with Blind behind and now you need a playmaker ideally, and Carrick is to static for me, but due to Fellaini liking a B2B role, Carrick will suffice.
Attack
Falcao needs games, and I want to see Januzaj behind him.
DDG
McNair===Jones===Rojo
Blind===Carrick

Subs: Valdes, Rafael, Herrera, ADM, RVP
