You have to put it in context .
Zidane was a flop in real b ,yet at real he had a world class squad. It's pretty hard to flop with it .
Seedorf and inzaghi had weak squads or aging players . Milan was a shit run club . They didn't had a working environment to begin with .
Now juve ,just won Seria A despite sarri, still has a world class squad for Seria A, probably the best there is , so for him to flop would be very hard .
If the players doesn't like him ,it is not out of the question that they would take matters into their own hands and get us through the finish line.
