Play a 4-2-3-1 asymmetric formation.
-------------Casillas------------------
Ramos---Albiol---Pepe---Arbeloa
---------------Lass---------------------
----------Alonso-----------Marcelo
Ronaldo---------- Kaka-------------
-----------Higuain/Benzema-------
I used this and won champs league n La Liga in my first year.
As far as roles are concerned,
Kaka - att mid (support); Ronaldo-inside fwd (attack); Alonso - deep lying play maker (support);
Lass - def mid (defend); Marcelo - Winger (attack); Higuain/Benzema - Advanced fwd(attack)
Hope it helps!
