A return to Dortmund would be an option for Jodan Sancho. If he stays at Manchester United, we will not see any improvement in his career. Ten Hag builds his squad with players of his choice. Even if the players don't perform well, ten Hag has no headaches. We can look at Hojlund as an example. Hojlund's performance with Manchester United's squad has not been good. However, Ten Hag have been giving Hojlund chances in almost every match. Hojlund scored just one goal in 15 matches. On the other hand, ten Hag's reluctance to keep Sancho in the squad is quite understandable. So Sancho should be without United.
There really is no other choice for Jodan Sancho because his feud with Ten Hag, Manchester United's trainer, doesn't seem to be getting any resolution, so to save his career, Jodan Sancho must immediately leave Manchester United and it must be admitted that being with Drtmund is more promising for Jodan Sancho to be able to improve its performance again.
And at the moment Dortmund are not in good condition, they have a lot of problems and I think bringing back Jodan Sancho is the right solution.
I don't know why United coach Ten Hag is not interested in a player as talented as Jodan Sancho. Manchester United management bought Jodan Sancho from Dortmund for a high price. Perhaps 85 million was spent by United Management. Jodan Sancho is a good enough player. Ten Hag didn't give Sancho much of a chance though. However, Sancho should now take on a new challenge. His future is not good if he stays with United. If he joins Dortmund, he will likely be in Dortmund's starting XI. He will get a chance to prove his ability.
