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.
Manchester United were another club interested in Diop, but have since focused their efforts on signing Harry Maguire from Leicester City.
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.
