I was actually thinking of this formation and it maybe radical but it might also work
----------Buffon-------------------------
------Zambrotta---------cannavaro--------------Matrix--------------Grosso
------------Camoranesi----------------Gatusso--------------------Perrotta
-------------------------------Pirlo--------------------------------
----------------------------Gilardino-----------Toni
Okay Pirlo has not played there in like forever but he would not have any defensive duties and he does have an eye for a killer ball
Also it gives Italy the option of bringing on later Totti, Dp and Inzaghi after 1 hour or thereabouts and no defence would not be very concerened to face those 3 with just 30 minutes or so to go
But its just fantasy, i dont think Lippi would every consider it, but i would seeing that Totti is not 100% and Pirlo is very suspect defensively
