Hyun-Seok Hong

In July 2025, reports cited a market value of €3.5 million for the player. Around the same time, he was loaned from Mainz to Nantes for a reported fee of €400,000. The most significant recent fee was his completed transfer from KAA Gent to FSV Mainz 05 in August 2024, which was reportedly for €4 million. Prior to that, he moved from LASK Linz to KAA Gent in August 2022 for a fee of €1.5 million.

Our valuation for Hyeon-seok Hong is primarily anchored by his €4 million transfer to Mainz in 2024, which serves as a recent high point. However, his subsequent struggles for form at both Mainz and on loan at Nantes, coupled with reports that Mainz is actively looking to move him on, necessitate a significant discount. The valuation range is therefore set below his last transfer fee and centered around the reported €3.5 million market value from mid-2025, reflecting his diminished negotiating position.
