Berardi is the only one of our current co-owns/loans I'm confident about becoming Juve material.
From the others, maybe one or if we're really lucky two can make the cut, but they most probably will get sold/used as makeweights and become key players at mid-table teams. And I really have no idea about who will turn out best of them.
All this excludes Leali though, as I have to admit I rarely saw him, and have therefore little right to judge him or his futute ability.
