I agree with you. Even though this season's results are better than last season and they also qualified for the Champions League next season, overall I see that Juventus has not experienced a significant improvement in performance. Results are better this season as Juventus only got 5 defeats with 2 games remaining. But they also did not get a significant number of wins. Most of them are draws. This must be an evaluation for management or coaches because next season they will play in the most competitive league in Europe.
Actually, if we compare Juventus performance in the last two seasons, of course last season was a better season for them, for you to know if it's towards the end of the last season at that time ,Juventus had to get a 10 point deduction so that from the second rank they dropped to 7th place, besides that Juventus was also banned from playing in the Conference League this season even though they finished in the Conference League zone last season and that's why this season we don't see Juventus playing in European competitions, so indeed the target pursued by Allegri is only to finish in the Champions League this season and it should be recognized if Allegri manages to do so.
As fans, of course, they want the best from their club so that failure and also continuing to get out of the Scudetto competition of course had makes Juventus fans are now getting fed up with Allegri and forcing the management to make major changes in the Juventus squad next season including a change of coach, reportedly now Juventus and Allegri have agreed to end the cooperation, So I think the Coppa Italia trophy won by Allegri is a sweet farewell gift for Juventus fans this season, most likely if Thiago Motta who managed to bring Bologna to the Champions League next season will be Allegri's successor for next season and he will be contracted for 3 seasons.
