The problem is sacking a dinosaur coach is only half the job
You need to go out of your way to replace them with somebody completely different but Juve refuse to hire outside of Italy.
Imagine refusing to buy players who aren't Italian regardlessof ability, it would be seen as the pinnacle of retardedness. Yet we do this with managers. The problem is, most of these guys all learned everything they know about football from the same fucking people in the same league.
