Borussia Dortmund chief Michael Zorc has shut the door on Pierre-Emerick Aubameyang leaving this summer.

Zorc insists time has run out for the likes of Chelsea and Liverpool to do business over the Gabon international striker.

Aubameyang is currently in China with the rest of Peter Bosz's squad.

Zorc declared: "The time window for his transfer is closed! Time has tipped the balance."

Aubameyang, however, is yet to publicly address his situation.
