Juventus really needs to fix the problems of its players, even though Motta may not feel that there is a problem with his players, he must be able to see that Juventus needs an overhaul that needs to be taken into account, in order to be able to return with a new enthusiasm to compete well in the next season. Looking for new players and recruiting talented young players must be done so that they have a goal scoring machine or their defense line. I hope Motta does his best for Juventus.
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.
The Juventus team is not weak. But this team is not strong enough to win the title. Last season we saw that Juventus' performance was not stable. However, Juventus managed to occupy the third place in the table. However, the Juventus team was 23 points behind Inter Milan, who are at the top of the table. Juventus had no qualification to win the title.
One of the reasons for Juventus' erratic performance last season was a weak attack. The performance of the defensive players was very strong. However, the performance of Juventus strikers was very poor. Juventus managed to score only 54 goals in 38 matches. Players On the other hand, Inter Milan players scored 89 goals in 38 matches. So if Juventus wants to win the title, they must strengthen their attack. I don't see any alternative.
