With Diego gone we could go 4-3-3.
Aquilani-Felipe Melo-Marchisio
Krasic-Amauri-Martínez
Di Natale could play striker, Pepe is used to playing in that formation with Udinese.
With Aquilani, this 433 is what comes to my mind too.
but you know, our manager is Del Neri... it will be 4411 or 442 or even 424 instead of 433
after selling Diego and Trezeguet we should have enough resource to sign some good SS. I was shocked by their (not confirmed) departure but I think we still have chance to do good in this mercato.
Robinho, Cassano, Aguero, Benzema, Ibra, they are all available
if money is not an issue for Agnelli, we have a lot of option
