If Marotta manage to get 1.5/2M for each loan for the next 3 years it's OK. It will total around 8M, paid in stallments. Unfortunately it isn't money right away, but that's what's possible.
Unfortunately Juve is a hostage of this fuckers. If they refuse to leave to a certain club, they have the right to do it, because their contract is with Juve. And if the wanna stay getting 3/4M a year just to show up at training they will. This is not a punishment to these guys who just want to rob the club. These fucking crybabes.
It's sad, but I don't see much more Marotta could have done.
