People are really complaining about Facundo freaking Gonzalez?!? commoooonnn...
If someone is a young talent with a pulse, people will complain that they're sold. Homegrown/young developmental players at NextGen having a long term at Juve are the exception, not the rule.
I'd bet on players like Mbangula, Savona, Rouhi, Anghele, etc that are making their debuts early this season will be sold within the next 2-3 seasons than have a long term future here. These guys are money makers in the books and unless you have a special talent (like Yildiz), chances are you wont make it at Juve.
And even guys that probably are talented enough to make it at Juve, like Soule or Huijsen, will still be sold.
So I wouldnt get attached to any of these players.
