Juventus was not a weak team before and they had many good players and got good titles in the past but time after time because of everything that happened in Juventus they lost power and that's why even Allegri couldn't have a good performance in Juventus. In fact, Juventus without or without Motta can't change anything by just using a new coach because Motta can't do miracles in Juventus.
We can't forget Juventus was one of the most successful teams in Serie A and now Motta has a lot many work to do in Juventus and he needs to make huge changes.
Juventus is in a phase where they are rejuvenating a club that needs to build with young players, and carrying out a phase like this really takes time and even the choice of coach must be correct, maybe Juventus made a mistake when reappointing Allegri but all of that was far from Management's expectations Juventus, appointing Motta as the new coach, of course had careful considerations and of course there were pros and cons, but everything went according to Juventus' wishes, that Motta has a passion for giving Juventus a pattern of play, even though we don't know Motta's performance yet, hopefully in pre-season we can see Juventus' development will be good or otherwise.
