Basically because Paratici spent (wasted) loads of money during a strong era for the club he had the right ideas...He spent something like €500m on players in the first two seasons and balanced the books with a method that also caught up to us, whether you agree with it or not.
I'm afraid what you're going to see from Giuntoli now is going to be far more like what Marotta had to do during the main part of his spell and crunch the numbers, precisely because Secco+ wasted our strong sporting and financial position.
