Arsenal have reportedly made an enquiry to West Ham United regarding the availability of defender Issa Diop this summer.
The 22-year-old centre-back impressed potential suitors during an excellent debut campaign in the Premier League during which he made 33 appearances.
Arsenal have already signed defender William Saliba from Saint-Etienne in this window, but the 18-year-old has returned to the Ligue 1 club on loan for the 2019-20 season.
According to The Mirror, manager Unai Emery spoke with West Ham about Diop's availability three weeks ago.
The French defender, who joined from Toulouse for £22m last summer, will only be allowed to leave this summer if West Ham receive an offer of £65m.
