The 28-year-old has been linked with a move to Chelsea and AC Milan, but the Bundesliga side have not received any offers and will not wait for long.
“We have not had any offers,” he told Welt am Sonntag . “We will wait a few more days but not long anymore.
“We have told Aubameyang: ‘if you want to move and have a club ready to meet our conditions, come to us and we will talk about it’. But we also explained that this is only possible within a certain window of time. We must find a replacement, which is difficult, if not impossible.
“Personally, I would prefer he stay with us, but there are a few clubs on this planet where he can obviously earn more.”
