Klopp is a bad example. We can compare our season to Pep´s first at City. They had the exact same agenda; to change their brand while in a win-now mode. City actually reached the CL semis the year before he came but did do better in the league with him, mainly due to Arsenal choking hard at the end. He also implemented this high line possession based style. Their defense was all over the place and he got widely criticized. Conte also destroyed him that 1st season. The difference with us is that our squad is so much stronger than the others that we still won + we got Cr7.
But what made him succeed at City, and I think will be the key for Sarri:
1. They got rid of the players past their primes: Yaya, Clichy, Sagna, Kolarov, Hart, Zabaleta etc (for Juve: Khedira, Matuidi, Higuain, Pjanic, even Bonucci etc)
2. The club backed him in the transfer window, will we back Sarri? (I know City manipulated the FFP but the point still stands)
3. Pep had the respect of the players and they bought into his style.
The 1st and 2nd point is on the club and the 3rd on the manager. The problem with Juventus ATM is that we fans don´t trust the club to do their job nor the manager to do his. So it´s too much uncertainty. Essentially we are the poor man´s version of City´s plan. The people in charge are questionable (Paratici) and Sarri himself too. So next year will be very interesting.
