Berlusconi is an idiot though.
That formation will probably get thrashed by inter and lose again "big" sides again, although it could be interesting to see what they can offer in attack.
I wouldn't really play it considering Milan's defense is not the best nor the fastest one so it could end up in rape.
Maybe they could play something like this?
Ronaldinho - Pato
Honda
Pirlo - Ambrosini - Flamini
Ronaldinho as SS, i would believe he would be given permission to roam to the left where he feels comfortable.
