In all honesty, I'd never accept players like Pogba or Vidal back simply because they were adored by the fans and club so they had no reason to leave except for more money.
Juventus managed to grow its stature without them so this proves that they never believed in the club's project.
Now when we can afford to offer higher salaries, they seem like they want to get back.
I'd rather buy new young prospects who have the hunger to prove themselves on a higher level than bring back old players who think that the world revolves around them.
