Arsenal have made checks on Real Sociedad's 19-year-old Spanish centre-back Jon Martin as an alternative to Piero Hincapie. With Arsenal's primary focus on securing Bayer Leverkusen's Piero Hincapie, the club has identified Martin as a potential backup option should negotiations for Hincapie falter. Arsenal's interest in Martin underscores their strategy to strengthen their defensive lineup amid ongoing talks for other targets such as Oscar Gloukh and Caleb Yirenkyi. Martin's contract with the Spanish club runs until 2030, and his market value is estimated by Transfermarkt to be €8.00m.
