FSV Mainz 05 are prepared to let 26-year-old South Korean attacking midfielder Hyun-Seok Hong leave. There is interest from Olympique Lyon and FC Toulouse in France, as well as from Turkish clubs Trabzonspor and Kasimpasa. Hong's contract with the Rheinhessen side runs until 2028, but it is unlikely he will remain with the club beyond the summer. He spent the latter part of the 2025/2026 season on loan at KAA Gent. The South Korea international has 16 caps for his country and a current market value of €2.50m, according to Transfermarkt.
