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.
Undoubtedly, Juventus is in transition. Motta in? Yes, it's smart, but don't overreact. This isn't an overnight fix. Man, the team has major concerns. We're talking about old guys. Expecting a Ferrari to win with a rusty engine is like that. Bringing in new blood is nice, but they won't change the team next season. It takes time for them to gel. They cannot just start scoring hat-tricks every game. Juve could be able to compete next season, but they won't rule Serie A soon. This will take time. Watch Motta handle this. Hard job awaits him
