Dortmund really showed their business side, even though during this season Sancho played so well in all competitions and this made him very worthy of being made permanent. But it was not so easy for Dortmund to make his move smooth and they asked Manchester United to give Sancho another loan.
I don't know for sure whether Manchester United will agree to this or not, but what is clear is that Sancho does not want to return to Manchester United and if possible he will go to another club if Dortmund's request is rejected. I think it's quite sad for Sancho because he is very comfortable at Dortmund but on the other hand Dortmund might want to know whether Sancho can be consistent or not because they don't want to be too hasty in making decisions and I think Sancho has to understand that.
Manchester United might still accept Sancho after seeing that they miss used him be he will be very useful for the team if he play alongside Huglund, but Ten Hag will be the main problem in that case because they had personal issues that led to Sancho's departure in the team.
Sancho on the other hand will not to go back to United because of his relationship with Ten Had unless if United decide to sack Ten Hag.
I don't know why Dortmund don't usually like keeping players despite all the effort the players made during the season. They are used to selling their key players without having replacement for then, and that action has been affecting their performance; I just hope United rejected this deal so that Dortmund can keep Sancho.
Well, the main key is that Manchester United must fire Erik Ten Hag first if they want Sancho to return, but if they can't do that then it's better for Sancho's future to stay at Dortmund. Moreover, he felt much happier at Dortmund and his performances improved impressively.
Maybe Dortmund knows that Sancho's potential is still not exhausted and the proof is that even though he hasn't played for Dortmund for quite a long time, he still made a comprehensive contribution throughout the season. Because of this, Dortmund is also trying to persuade Manchester United to take another season on loan and this step is very appropriate if you look at Dortmund's actions in the world of football business and player transfers.
