I can't believe Barzagli would be that stupid. He can probably kiss his position in the Azzurri goodbye, and he was marginal at best to begin with.
Refusing Fiorentina with a very good coach in Prandelli, and the exposure of playing in the Champions League, for UEFA cup toiling in a second-rate club like Wolfsburg. Sure, Luca Toni went to Germany too... but he went to Bayern Munich... huge difference.
