Juventus could use Sancho a lot better, United is having winger crisis and STILL not using Sancho because of club drama, that makes no sense at all, why wouldn't a team want to use their best player that they need on a position that they are having trouble with, just because of some drama. They are even using Antony when they can, which would be a dramatic situation to be fair, because it's obvious that he is in trouble with legal authorities and that sounds like a bigger deal, and yet they are still using him and not Sancho.
If Sancho goes to Juventus, at the very least, we could say that he is going to be a lot more used and a lot better, it will definitely help him a ton and he should be getting minutes to show himself again.
In fact, what is more surprising to everyone is the silence of United management regarding the resolution of the drama involving Ten Hag and Jadon Sancho. I think the impact of this drama has more or less affected the dressing room, especially when United is short of players, Sancho should be a pretty good rotation option. In fact, up to now Sancho is still unused in the main squad, and the club has to pay a certain salary without getting any contribution due to this conflict.
Agree with you regarding Sancho future if he joins Juventus in the January 2024 transfer window, he will rediscover his best playing form to prove that United management was wrong not to use him well. There is only one main obstacle, the amount of Sancho transfer fee will not be cheap, and according to media reports, Sancho is not to be loaned out.
