I support this idea. I also want to see Sancho being a permanent member of Dortmund again. He has no future left at Manchester United. It is because of the tension between ten Hag and him you know. He refused to apologize to his manager and he got removed from the squad with immediate effect. 

Dortmund would also love the idea of signing Sancho back. You know how beneficial he was in the past. He belongs here obviously.    The new manager Nuri Şahin would like to work with him for sure I assume.
