Arsenal didn't have them either. It was a very similar situation to us now.
A long time legend coach got fired because players gave up, a soft coach came in and replaced him, got some results initially, but players realized they could walk over him and gave up there too.
Arteta came in, won 2 trophies immediately, but as soon as difficulty hit again they gave up. Some players were left over from the previous regime, some new older players and some new younger players. They didn't have a real captain (Xhaka), but had a 'captain by committee' where players voted for the captain, it was a complete mess.
Once the players realized they weren't going to sack him again they started trying again, management backed him and changed most of the team, now they have a promising future.
Not saying same should/will happen here, but management and coach were hand-in-hand. Here we have Agnelli who is pro-Allegri safe to assume, I think Cherubini too. Nedved is his biggest enemy and Arrivabene probably would fire him too but cares too much about finances, that's his job. And Allegri who probably has some hard feelings from the first stint, feels hard done by the first sacking, now the same guy who sacked him still hanging over his head etc.
Either Nedved or Allegri have to go IMO.
