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.
It seems to me that Motta has very similar preferences in strategies with Alegre, they both emphasize defensive play, in fact this is a characteristic of Italian football, so this is not surprising. Therefore, I do not expect big changes in the team with the arrival of Motta, especially since he does not have good strikers at his disposal with whom he could try to change something at Juventus. In addition, today it became known that Juventus will most likely lose Rabiot, and this is a very big loss for the midfield. So I don’t see any reason to be positive.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.
