Not really.
Milan's bench: Inzaghi, Robinho, Sokratis, Seedorf, Antonini/Abate, Gattuso/Boateng/Flamini/Ambrosini depending on who they play.
Inter's bench: Pandev, Materazzi, Mariga, Santon, Coutinho, Motta (is he playing?), Mancini
Juve's: Del Piero, Sissoko, Martinez, Legro, Lanzafame, Pepe
I know i missed a few but still i would say Inter's bench is better.
And to be honest i wouldn't consider Milan a WC team at the moment, on paper perhaps yes, but they're too shaky for my liking.
