Donyell Malen is rumored to be leaving Dortmund in the winter or even in the summer. He has also signed a contract with a new agency and I think Donyell Malen also seems to be alert to the situation that will exist in Dortmund. The reason is that now Dortmund has started to persuade its former player who is currently at Manchester United, namely Sancho, to return to Dortmund this winter and if that happens, maybe Donyell Malen will just have to wait for a proposal to leave Dortmund. I don't know the specifics of the current situation and if that is the case, it is possible that Donyell Malen would prefer to leave Dortmund considering that his position may also be threatened by the presence of Sancho.
