Juventus fans really hope that next season so that Juventus will no longer look bad and unable to compete for the top flight in the League. Even though Motta is a new coach at Juventus, I am sure he will use his experience and knowledge to see what Juventus' current condition is so that he can plan quite the right decisions like the several options you have mentioned. Because recruiting talented young players is an option that almost all teams want to do every season in order to make the team's strength even more formidable.
I myself am not a Juventus fan, but in my opinion Juventus is starting to lose its glory days. It's difficult for them to return to their glory days because they haven't overhauled their players, because with what @Velvet78 has said, Juventus does have quite a lot of players who are getting older, so of course their performance will no longer be as enthusiastic as before. Even though Juventus still has the opportunity to perform better next season, it is very likely that they will experience some difficulties because of their players who in my opinion need to be improved.
Indeed, by recruiting young players of course it takes time to adapt and become the best of the best, of course Motta will do his best with the players he has, Juventus can compete closely next season if they are able to fix their performance problems and other problems.
Motta replaces Allegri, who was fired at the end of the 2023/24 season after Juve had to settle for finishing third in the Serie A standings. Meanwhile, Motta had an extraordinary season with Bologna, leading the Rossoblu to sit fifth in the final standings. After officially becoming Juventus coach, Motta has carried out his first crazy transfer scheme with I Bianconeri. It will be interesting to see what Motta's progress will be like at Juventus next season. However, he will clearly immediately start his work to prepare the team, including buying and selling players this summer. According to news, Juventus is reportedly getting closer to signing Aston Villa midfielder Douglas Luiz. Motta really wants Luiz to join the squad. With this transfer, Juventus seems to really have high expectations for Douglas Luiz. It will be interesting to see whether Douglas Luiz will shine with Juventus under Thiago Motta.
