He is very good. But we need him to be great.
Aside from that, if we don't sell Sandro (or any other top player), a mercato of Schick, Betancur, Bernadeschi, Danilo, + a top CM... that's fantastic.
Anyone saying otherwise is going full retard for no reason at all. We don't have the money to have a net spend of minus 150 mil. Getting such young talented players, and a top class RB to replace Alves. Those moves are fantastic, for Schick, Bernadeschi, Danilo, Betancur.
Ultimately, it all hinges on 1 midfield signing. We need someone already established and top class. That's the final step for us. A Vidal level CM.
