Hyun-Seok Hong

In June 2026, reports cite a current Transfermarkt market value of €2.5 million. A year prior, in July 2025, his market value was reportedly estimated at €3.5 million. His most significant recent move was from KAA Gent to FSV Mainz 05 in August 2024 for a reported fee of €4 million. A subsequent loan move to FC Nantes in July 2025 included a reported fee of €400,000. For context, his transfer from LASK Linz to KAA Gent in August 2022 was for a reported €1.5 million.

Our valuation for Hyeon-seok Hong is driven by his reported decline in performance and market value since his €4 million transfer to Mainz in 2024. With the club reportedly open to a sale and his most recent market valuation cited at €2.5 million, our estimate reflects this current value, while the range accounts for potential negotiations given interest from multiple clubs in France and Turkey.
