Jack, I didn't like the hiring from the outset. However, you can't just throw him to the curb after 3 months. And it has nothing to do with the fact that he is a former Juve player. Getting rid of him now just smacks of desperation, and it is not something that an "elite" club does.
Unless of course, Juve are no longer elite. And if that is the case, then all bets are off
