Can't see us playing 4-4-2 tbh.
I'd go for this if we have ditched 3 at the back:
--------------------Green---------------------
Isla----------Caulker-------Rio-------------Yun
--------------------Sandro--------------------
-------------Barton----------Fer--------------
Hoilett--------------Austin--------------Traore
If we play 3 at the back:
----------------------Green--------------------
-----------Caulker------Rio--------Ned---------
Isla--------------------------------------Traore
----------------Sandro------Barton------------
-----------------------Fer---------------------
----------------Austin------Vargas-------------
