Rizespor have begun discussions with Arsenal regarding a potential transfer for 23-year-old goalkeeper Karl Hein, as reported by Turkish transfer expert Reşat Can Özbudak. The Estonian international, who is in search of more first-team opportunities after making only one senior appearance for Arsenal, is also reportedly a target for Rangers. Last season, Hein was on loan at Real Valladolid, where he gained important experience, even though the team was relegated from La Liga. Additionally, Sevilla has expressed interest in acquiring the goalkeeper, intensifying the competition for his signature. Hein's contract with Arsenal is valid until June 30, 2026, and Transfermarkt estimates his market value to be €3.00m.
