I don't understand why you compare Conte to any other coaches.
Any self respected person would recognize the difficulties he's facing and try to get with them.
It's only Conte who can work only work in ideal laboratories standards. When he spots a setback to his job, not only that he quits, he also actively adds to the problems. Look at his time at Chelsea, he gave up yet refused to leave and even brought it to the court. We also had to pay him 7m so he can fuck off. Yes, I understand his mind is so set on winning and winning alone. But if you can't continue due to uncontrollable circumstances, be self respected and resign. There was no reasons to pay him to leave other than knowing he would actively sabotage the club further which he had done before.
Look around, Zidane, Ancelotti, Mourinho, Klopp, etc... all have to deal with set back before. They are all CL winner calibre coaches, none of them behaves in any way close to Conte.
