Management (Paratici) have put themselves in a hole, by their sole fault. The inflated wages given to veterans, mercenaries and busts (including Sarri) in the past 2 seasons is now finally blowing up their faces. For anyone who paid attention, it was coming. Covid just exposed it quicker.
Agnelli is quite probably very pissed about it. Just a question of common sense. Paratici and Nedved managed to, at once, weaken the team and finances. It started with some deals from Marotta, sure, but Paratici made it considerably worst (if he is, indeed, the responsible for the "strategy" in football, and if Nedved takes part in it).
I'm sure Paratici's ass in on the line. Unless he cleans the mess with some great deals this summer, all while retaining scudetto for next season, I think there's a good chance he's gone in 2021. It just wouldn't be feasible or smart to sack him now, with little preparation time for next season and with the strategy already lined up for the cleanup.
The 300M "expansion" is, if I'm not mistaken, debt. Plusvalenza also is like pulling the shit under the carpet (gaining some immediate relief, for some long term debts).
So, unless a lot of stuff goes right, I think he'll be gone. Odds are stacked against him. He's undone a good part of things that were working before.
