We'd have completely destroyed him and he'd have been another version of Melo.
It took him one season, lots of support from important figures like Berlusconi and Galliani, lots of support from his teammates and his countryman Leonardo, to get back to this form.
In Juve, with guys like Secco, Blanc and a coach like Ferrara, with players around him who can't pass the ball even if their life depends on it, Dinho would have been some 20kg overweight flop by now.
