If Falcao indeed signs I really hope that is the plan. Selling Rooney and in progress making ourselves weaker again makes no sense to me. But I could definitely see us signing another striker with Rooney moving back and one, maybe two of our attacking players being moved on.
Out: Nani
In: Falcao
ST: RVP, Falcao, Hernandez
Wingers: Valencia, Welbeck, Young, Zaha
AM/CM: Kagawa, Rooney, Carrick, Cleverley, Anderson, Giggs, Jones (Fletcher)
We would still need a new CM mind.
The questions is whether Rooney would be disciplined enough to play in a midfield two beside Carrick. Zaha (I think he'll be star from the start), Welbeck and RVP behind Falcao.
