That is according to reports published in 'LÉquipe', though the veracity of the story is yet to be established. In other circumstances, it would be easy to envisage such a move, however Atletico are currently banned from registering new players until January after their appeal to the Court of Arbitration for Sport failed.
Signing Aubameyang in January would be an option for the 'colchoneros', something they are also considering doing with Vitolo and Diego Costa. However, in that case, questions would be raised about whether Dortmund should name the player in their Champions League squad.
It is well known that Borussia Dortmund will not listen to offers of less than €70million, but that he is available for the right price.
