The Gabon international swiftly appeared on the radar when Alexis Sanchez's switch to Manchester United edged closer.
Now, according to The Sun, the Gunners could be making their second signing in as many days as Dortmund boss Peter Stoger wants Aubameyang's future to be resolved quickly.
"We would like the solution to be there tomorrow, whatever it looks like," Stoger is quoted by the newspaper as saying.
"I probably would speak from the souls of many people, causes everything that has been clarified and brings clarity, is good for everyone in their life and would also be good for us as a team."
The report claims that Arsenal could end up paying around £53m to secure Aubameyang's signature.
