I think Juventus' decision to recruit Thiago Motta was the right decision and not rushed. Because he deserves it, especially since he is already familiar with Seria A, as you said. So Thiago Motta is very optimistic that he can make Juventus again a strong team in Serie A, he will change the sick mentality that Allegri left at Juventus.
This is because Thiago Motta is known for his adaptable approach, often changing formations depending on the game situation, so he is very suitable to coach Juventus. So for Thiago Motta there is no difficulty for Juventus, remember that when he coached Bologna he was able to overwhelm Inter. In three matches, Bologna managed to win once, draw once and lose once. This proves that he was very successful with Bologna, which we know has a modest squad. So with the squad that Juventus has, I think he will be able to bring Juventus to become a contender for Serie A champions next season.
The change of coach carried out by Juventus is certainly one of the things that has been done to change Juventus' performance to make it even better and return to dominating and become a strong team. With Thiago Motta who will coach Juventus, of course Juventus has the hope of being able to return to having a strong performance, but the problem is that Juventus does not have talented young players, Juventus has many players who are getting older which can make it difficult for them to get better performance. , and if Thiago Motta does not recruit talented young players then he must be able to bring Juventus to better performance with the available players, even though the players are experienced, it does not rule out the possibility that their stamina will decrease which could affect their performance.
If Thiago Motta really adapts easily, of course that's good, because all teams that get new coaches need time to adapt to each other, and if Thiago Motta can adapt quickly that will be good for Juventus. There is a good opportunity for Juventus to be able to compete better than before under the guidance of Thiago Motta.
