I like 4-2-3-1
Rafael Evans Jones Shaw
Blind Herrera
Falcao Mata/Rooney Di Maria
RVP/Rooney
I don't really know if Falcao can play wide though. More realistically may be:
Valencia Blind/Herrera Di Maria
Rooney
Van Persie Falcao
No Rojo?
It seems to me that van Gaal is hell bent on this 3-5-2. If you assume he's going to line up that way, who plays where? Any way I look at it I can't see how your 'big 5' (rooney, rvp, falcao, di maria, mata) can all fit in.
My belief is that one of those three strikers will be on the bench and whoever it is won't like it. And I also get the feeling that Mata will be on the outer once again. Wouldn't be surprised to see him and Fellaini sold in Jan.
