I dont think they will cause any trouble. They are far from Higuains situation. They are professionals and they are surely not going to make any fuss about anything. Higuain's head is completely f***ed since he left us, nothing has been going his way so im pretty sure he will try to squeeze every dime from Juventus with no regards for whats best for our team too.
Man, the Serie A title Higuain gave Juventus is really underappreciated. He was by far and away the most important player of the 16-17th season.
Of course, from there it went downhill, and the guy's reputation (and apparently his mind) is done. And sure, Marotta overpayed for an ageing player, who is now a problem.
But he should be respected for that Serie A title alone.
Hopefully they find a solution... it's gonna be tough. He doesn't strike as a China mercenary. I think there coul be a chance he actually remains in the squad. Would be glad if Juve could simply shed the salaries completely off.
