Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
Reports from December 2025 cite a Transfermarkt valuation of €2.5 million. This figure matches the reported fee Celtic paid for his transfer from Gangwon FC in July 2023, which was also €2.5 million.
Our valuation for Hyun-Jun Yang is anchored by his €2.5 million transfer to Celtic in July 2023 and a matching Transfermarkt valuation. His status as a key player with Champions League experience and a long contract until 2028 suggests Celtic would seek a profit. Interest from clubs like Birmingham City and Legia Warszawa points to a modest increase in value, rather than a major leap.
