I don't know, really. At least Rino seems to try new things every now and then, Pirlo fields the same thing all the time.
Imagine his Juve once CR7 leaves and we end up with (obviously) a lesser forward to lead the attack.
If Pirlo stays, we're fucked. Gattuso is not good enough either but at least he reconstructed Napoli which was falling apart under Ancelotti.
Either way, our only real upgrade options seem to be ZZ and Allegri. All the other names that we've been linked to are shit.
