Arsenal are reportedly concerned that both Pierre-Emerick Aubameyang and Alexandre Lacazette could leave the club this summer.
Aubameyang has endured a challenging campaign on and off the field this term, but he committed his future to the Gunners last year and is tied down to the North London club until 2023.
Meanwhile, Lacazette started to hit a rich vein of form before succumbing to a hamstring injury, and with the Frenchman's deal due to expire in 2022, he is being heavily linked with a switch to Atletico Madrid or Roma.
According to the Daily Mail, Arsenal are worried that both players could end up departing the club this summer, leaving Eddie Nketiah and Folarin Balogun as their only two recognised strikers.
The report adds that the Gunners could look to move for Borussia Monchengladbach's Alassane Plea as a replacement for Aubameyang or Lacazette, but they would have to fend off interest from Manchester United to land the £15m-rated forward.
Arsenal have also been linked with moves for Celtic's Odsonne Edouard and Gent's Roman Yaremchuk as Mikel Arteta plans an overhaul of his forward line.
