Okay, visualize this: My personal formation 4-3-1-2
(GK)Buffon
(DR) Thuram, (SW) Juliano/Ferrara, (SW) Montero, (LB) Birindelli/Pessotto
(MR) Camoranesi, (DMC) Davids/Tachi, (ML) Zambrotta
(AM) Nedved
(ST) Del Piero (ST) Trez
*If Zambrotta can adapt his play on the left flank, then he can definitely be Juve's new left midfielder. Davids can cover the middle, winning ball from opponents and helpingout in attack making those insertions similar to nedved's. Tachi can play this position too if he recovers his form. But I have to say thought that he needs to add a little flare to his attacking play. As laresca said, his creativity leaves a bit desired.
