Juve have no need for Tevez. Juve have an amazing team with at least two players capable of filling any role. Tevez would rot on the bench since he would not be able to unseat either Del Piero or Nedved. Enzo Maresca is enough young talent for Juve right now, besides i'd prefer to see them invest in a young serie A player. With De Rossi, Marchonni (who given Parma's financial situation will be available) or Di Natale good bets to be signed by Juve. Last rumours i heard about purchases by Juve from south america is Fernando Cavenaghi (River Plate) and Gonzalo Rodriguez (San Lorenzo).
That's aleady been done with Appiah. As for Tevez, wait and see. I think d'Allesandro [sic] made a wise move when he switched to Wolfsburg. It gives him a chance to adjust to Europe. And if he's successful, he ups his value. Anyway, I'd keep my out for him before buying Tevez.
