Borussia Dortmund are still waiting for interested clubs to firm up their interest in Pierre Emerick-Aubameyang.

BVB chiefs have confirmed they're prepared to sell the Gabon ace this summer - but want a deal done before preseason under new coach Peter Bosz kicks off in a fortnight's time.

Chelsea and AC Milan are the latest giants to be linked with Aubameyang this week, however Sky Deutschland says BVB are still to field a concrete bid.

BVB director Michael Zorc revealed: "For now, we assume that Aubameyang remains. We agreed with him that we will remain open to discussions, but only up to a certain amount of time will we wait."
