Sarri to Juventus makes zero sense.
1. His entire style completely depends on the midfield. If the management are going to invest heavily in the midfield, why letting Max go if that is what he hadn't have since Pirlo, Vidal, and Pogba left the club? You don't part with the manager like Allegri because he didn't have the team he wanted in order to build the team for the new manager who's obviously less qualified than Max on every level. The only case when it makes sense it's when you sign another proven champion, like Pep. Not some loser.
2. The way Sarri handles difficult situations is atrocious. He thinks it's ok to say things like "I did everything right, I don't know how to motivate these players to play better, they probably don't deserve to be here" when you're under the pressure and your team play like shit because you have no clue what to do if top players you have don't fit your one-dimensional primitive game plan.
3. His personality is too cringeworthy for a premium lifestyle brand Juventus try to become.
