The mistakes already been done, the old lady's already learnt from their mistakes. Juventus suffered from disappointment this season, and they have nowhere else to place their hope other than resolving the issues and facing the severe punishment that cost them a great deal of financial losses the previous season.
Juventus did not play too bad in the last season but they even could get better result if they were not massively and repeatedly attacked in Serie A. Those multiple attacks against Juventus affected their player psychology a lot and surely affected their performances for Juventus.
I think the effect is not so significant on the players, on average they finish the game well, and we see that firsthand, but indeed the incident made the team suffer so they couldn't take part in the champions league.
But one thing is guaranteed: they will bounce back as long as they strive for more proficient in their performance, since I can't think a top club like Juventus not making it to the UEFA CL berth implies they're completely out of the league of elite clubs to win the scudetto. Massimiliano Allegri intends to make some additions during the transfer window in order to improve his club's performance next season.
Juventus if totally focus on Serie A, will be a very competitive team there. If they use full energy for Serie A, they will be able to maximize their performance and increase their competitiveness to win Scudetto. A biggest task for Max and Juventus in this season is keeping Dusan Vlahovic in their club. He is still one of best young strikers and can contribute good performances for Juventus. They need him to win Scudetto in 2023 - 2024 season.
Maybe that is the step that massimiliano allegri should have taken, actually in my opinion there is no need to improve more because if he is able to maximize the potential abilities possessed by the Juventus squad to play very well again, and what needs to be fixed is management and improving training methods.
Dosan Vlahovic is indeed very important for Juventus' attack line, but I have not found that Dusan will really stay and the news circulating that Dusan will leave Juventus, hopefully it doesn't happen and he stays with Juventus for next season.
