He ain't leaving this season... Next season maybe he'll join barca Or madrid
He might leave if a good bid arrives, in his latest interview he did kinda hint Dortmund that he is going to leave.
I think he will stay for another year then leave in 2022
In his latest interview he seemed very oppose of the idea of staying at Dortmund and its clear that he wants to leave but the question is whether any team can afford to buy him.
dortmund probably wont sell him this year
