The 22-year-old Ivorian centre-back has been a key player for Bundesliga side Mainz in recent seasons.
The defender is rated as being worth £13.5m by Transfermarkt.
The energy of Gbamin would be crucial against Manchester City. Unai Emery has so far moved to bring in experienced defenders such as Sokratis Papastathopoulos and Stephan Lichsteiner, both aged 30 or older. The energy of Gbamin as the back would prove useful coming up against the creative Manchester City attack, who require constant tracking runs.
Unai Emery should do everything to bring the player in before the Gunners face Manchester City.
