In every season there will always be differences when a coach arrives at Juventus, because basically all teams must be trained with the right tactics and determination so they can produce more good things through their own players. Juventus is not a bad team and the fans must have confidence in the new coach who comes to Juventus in order to improve Juventus and be in a better position in the League next season. And every pressure must be handled better by the team and also the coach, even though it is not an easy way because every process always requires time and a higher level of will.
Juventus will start a new era under the coaching of Thiago Motta, so there will indeed be many changes that may occur next season, Juventus is currently starting to target many players who are indeed needed to support Motta performance next season, Juventus has experienced a significant decline in performance although they are still able to compete in the top tier of Serie A but they actually experience inconsistency in their game so that Juventus slowly makes Juventus Eliminated from the Scudetto title race last season, Allegri has been at Juventus long enough that he has managed to instill his philosophy of style of play which is now quite old-fashioned, so it will indeed take a long time for Thiago Motta to rebuild Juventus to play modern football.
Currently, Thiago Motta has tried to recruit some players that are needed and will be adapted to the style of play and also the strategy he has applied so far, Thiago Motta is of course a pretty smart coach, so I think he will be able to build Juventus to compete again in the scudetto race in Serie A but even so, of course Thiago Motta needs the support of the current Juventus management and fans for do it.
