I still cant find a single thing that I like about that old styleless man, but whats fair is to give him the whole season to prove himself.
And after the season end it will be very, very easy to judge him - all he has to do to prove that he is better than the previous coach and an actual upgrade is to top Allegri`s debut season, meaning winning a treble is the only way for Sorri to be considered an upgrade and worthy of Juventus, simple as that
A domestic double with a loss in the Champions League final would equal Allegri`s debut season, so after being on par in the only thing that actually maters -
silverware - fans and the club leaders can compare them in whatever way they want and like.
Anything less than a domestic double and a Champions league final means that Sorri is an obvious downgrade to Allegri and needs to get the fuck out of this club immediately and be replaced with someone better, which considering Sorri`s level wouldnt be that hard to find... Easy peasy...
