It still amazes me how Juventus losts completely from the scudetto title race this season. The Old Lady's are no longer competitive to grab significant winnings in matches and led them to record inconsistent performance and it'd really terrible. Juventus will stand up again but we're yet to speculate the time for them since they're having a rough time this season. Massimiliano Allegri is doing his best to revived the club back to winning ways, it's hard but it ought to be accomplished.
In my opinion, Juventus' problem lies with its coach, Allegri. This season there should be a big chance of winning the Scudetto title because they don't have a European competition schedule so they can focus on Serie A, but in reality Juventus doesn't take advantage of this opportunity, and often loses. points that made Inter successful in winning the Scudetto easily even before the season ended.
So my conclusion is that Juventus' current problem seems to be with the coach. Juventus, which usually regularly wins the Scudeto title and often appears in the UCL final, now seems to have lost power. Three years without clarity on the game system and its progress, what do you want to expect from Massimiliano Allegri? This is a clear failure as a coach.
Juventus had to fire Allegri, because his thinking and tactics were very pragmatic and outdated with just the same tactics. It is impossible for Juventus to win the Scudetto next season if Juventus is still coached by Allegri. Even if Juventus succeeds in winning the Coppa Italia trophy, Allegri deserves to be fired.
