Juventus has so many players who are over 30 years old. This needs to change immediately. They need to evolve into a more dynamic team to fight harder for Serie A titles. Football is changing and dynamic teams are one step ahead now. 
Motta is a young manager which is a plus for Juventus about this topic. I wouldn't expect him to prefer old player signings much. His system would also be different from Allegri probably. But before anything else, they need new transfers like I said before. If they sign midfielders who can contribute much more to scoring, it isn't too difficult for them to stay in the title competition until the final moments.
That's true, of course with their players who are over 30, their performance can decrease and this must be taken into account because this will certainly have an impact on the quality of Juventus, and their performance could also decrease because there are several players who have already entered their old age. It could be said that it's time to retire, even though not all players are old enough, because at that age of course they could experience a decline in performance and that could affect Juventus' performance.Motta is a young manager which is a plus for Juventus about this topic.

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.
