Arsenal's interest in Serhou Guirassy is a contingency plan in case Pierre-Emerick leaves the club.
Aubameyang, 31, has one year remaining on his contract and extension talks have stalled.
The Gunners could recoup some money for the star striker this summer, with Real Madrid and Barcelona reportedly interested.
Metro says Mikel Arteta has identified Guirassy as a potential replacement for Aubameyang.
The Frenchman scored 7 goals in 25 appearances for Ligue 1 side Amiens this season.
