It's hot..
I really think we should try the 4-2-3-1 also, atleast have players that will switch from a 4-3-1-2 to 4-2-3-1 without a problem..
Like :
Buffon
the Defence
Melo-Sissoko
Camoranesi-Diego-Giovinco
Amauri
When Del Piero is fit
Buffon
the Defence
Marchisio-Melo-Sissoko
Diego
Amauri-Del Piero
