Arsenal boss Mikel Arteta has previously hinted that Gabriel Martinelli can be Pierre-Emerick Aubameyang's long-term replacement.
The Gunners were keen to find a successor to the Gabon international this month and football.london previously reported that they were open to offers for Aubameyang, who was stripped of the club captaincy last month.
Technical director Edu had been chasing Dusan Vlahovic before the 21-year-old opted to sign for Serie A giants Juventus instead, leaving the Brazilian transfer chief scrambling to find a replacement before Monday night's deadline, with Real Sociedad's Alexander Isak one of many strikers linked.
