Our roster has no attacking mids. Villa should be down in that spot, because he's our best player and it's our biggest weakness.
You could call it a 4-4-2 Diamond, but I think it would play more like a 4-3-1-2.
Code:
------------Nemec-------------Mullins-----------
------------------------------------------------
---------------------Villa----------------------
------------------------------------------------
----------Mix---------------------Poku----------
--------------------Jacobson--------------------
---Calle-------------------------------Brovsky--
--------------Wingert-----Hernandez-------------
Jacobson stays in his typical deep defensive midfield role, and Mix and Poku also play with an eye on defense due to our overall weakness back there. With those seven players in the back, we can play possession all day long.
Key to this formation then is Villa in the CAM spot. Move him down there, and suddenly we have the ability to turn our impressive possession numbers into actual attacking chances. In addition, it gets us two more strikers on the pitch, who are good at receiving crosses and finishing, so those chances won't be wasted as often.
Shelton is the first man off the bench, and can come in for any of the highest five players with just a small formation adjustment.
I think it's optimal and am actually surprised nobody has brought this up before.
When Lampard arrives, Villa can go back up top with Lampard as the CAM.
