For now, especially after seeing Juventus' performance in the Club World Cup, Juventus is still very weak to compete in Serie A next season. There are still many things that need to be changed by Igor Tudor, besides that he also has to bring in players who play as defenders and midfielders because currently Juventus' game is very difficult to create opportunities to score goals so with the existing squad I doubt Juventus can compete for the trophy next season.
Indeed, next season Juventus will start a new chapter after last season which was full of turmoil and full of uncertainty. but the club management finally made an important decision by appointing Igor Tudor as permanent coach. Tudor came not only bringing tactics, but also a tough mentality that was once the hallmark of Juventus in the past. But again as you said they still need imaginative players, so they still have the opportunity to bring in some new players. if we talk about Chiesa, Liverpool also doesn't play him often, maybe when he came to Liverpool he was not in good condition maybe still in recovery, we'll see next season whether he is able to adapt to the EPL and succeed with Liverpool.
I've been telling you for a year that Juventus is in a very very bad situation, a team in disarray. If it manages to hold on despite everything, it is due, i don't know, to the strength and pride of the team, otherwise it would be even worse, trust me.
To fix it up you need to invest some money.
