Bisogna volere is what? He/she wants to wish? haha, think thats wrong.
Buffon came on board, in what, 99 right? Been with Juve for 6 years now. It all depends on what the offers are. I say Juve is what it is today, partly because of Buffon. Hes defly class, and is known as THE best goalkeeper in the world, period. Kahn was years ago, today its Gigi.
