Every coach has a different match strategy. And there are some favorite players. Allegri was the coach of Juventus for a long time. Juventus have now changed their coach. New Juventus coach Paolo Montero will certainly want to build his squad with players of his choice. So next season we will certainly see some big changes in the Juventus squad if the Juventus management gives Paolo Montero full freedom in the formation of the squad.
I'm not sure if Juventus will want to sell 26-year-old Federico Chiesa. Federico Chiesa's fitness is good enough. Last season he probably had 9 goals and 2 assists. However, Juventus management may decide to sell Federico Chiesa if they get a good price.
Juventus has a lot of old players. I think this is a problem and I don't know why the previous coach still kept the same squad without regenerating. Thiago Motta must be able to build a better squad. I hope the club board gives Thiago Motta freedom and sufficient budget and I hope the new coach will regenerate the Juventus squad. Because in my opinion, if Juventus does not regenerate now, in the next season or two they will find it difficult to compete with other teams and may suffer a bad fate.
