The formation above by La Grande Inter is the most commonly used one, but we also have the option of going to a 4-2-1-3 formation, which can be deadly, if appropriately used. In this we have:
---------------------------Julio Cesar---------------------------
---Maicon-----Lucio---------Ranocchia (But Samuel is back)---Nagatomo
--------------------Zanetti-----------Cambiasso---------------
-----------------------------Sneijder-----------------------------
--------Milito-----------------Pazzini-----------Eto'o---------
And as for the rumours, I doubt we would buy a winger, its useless, we saw what happened with Quaresma, so I think Pastore would be a better option in the following formation:
------------------Julio Cesar------------------
-----Maicon-----Lucio---Samuel----Nagatomo---
-----------------Zanetti----Cambiasso----------
-------------Sneijder--------Pastore---------
----------------Pazzini----Eto'o------------
However, this formation is very risky as Inter are not used to playing in such, but something along the lines of the above, tweeked a bit could used if Pastore comes.
FORZA INTER!!!
