Chelsea warned over striker bid

Aubameyang is known to be one of the most sought after strikers in Europe this summer but Dortmund CEO Hans-Joachim Watzke, says they have yet to receive a bid.

The Bundesliga side would prefer to keep hold, but if they do decide to cash in, they need time to draft in a replacement and have now set a deadline for any bids.

"We do not have any offers," he revealed. "We will wait a few more days, but not more. I personally would prefer him to stay. But it is true that there are several clubs in the world where he could clearly earn more money."

Chelsea boss Antonio Conte is weighing up his options after missing out on Romelu Lukaku, and Aubameyang is said to be one of them, but he will have to move quickly or risk more disappointment.

Liverpool, AC Milan and Chinese Super League clubs area also in the hunt so the race for Aubameyang's signature could be about to hot up.
