The thing with Dybala type players, is that you have to use them very specifically to get the best out of them, and sometimes that happens at the expense of the team. In that sense and financials apart, its a very
un-Juve signing. Its players like Licht, Asamoah, Perreyra, Marchisio, Tevez even the likes of Padoin to a lesser extent that signify what this team is all about. The collective. Players willing to sacrifice for the team and being able to adapt to their roles and circumstances.
Its the same problem Barca have with Messi, but luckily for them, he's good enough to ensure things on the pitch don't get Messy at all.

All that said, I hope the player has the maturity and ability to make sacrifices to contribute to the cause while making a name for himself.
