Pochettino at Tottenham reminds me of Ancelotti at Juventus. The way he lost EPL title to Leicester in the game against Chelsea reminded me a lot of that Perugia night (even though the tournament math was different). Having failed at Juventus, Ancelotti became a Milan legend. Poch has potential (including the type of personality he has) to follow a similar path. And his family's connection with Turin would make this story even more interesting. Also, he's already used to working with the tough club management and with no transfer market presence at all. I'd give him a chance at Juventus.
As for Sarri... Sarri + De Laurentis + Naples =

. They all fit perfectly together. None of the parts of this equation should have anything to do with Juventus.
