There is growing speculation regarding Hyun-seok Hong's potential return to AA Gent, a club where he previously enjoyed significant success. Currently, he is under contract with FSV Mainz until mid-2028, and his market value is estimated at 3.5 million euros. While there is interest from Belgian clubs, no specific teams have been identified. Hong's stint at FSV Mainz has been challenging, as he played only 519 minutes across 23 matches last season, without scoring any goals and providing just one assist. This contrasts sharply with his performance at AA Gent, where he made a notable impact by scoring 18 goals and assisting 20 times in 104 matches. FSV Mainz secured his transfer from AA Gent in the summer of 2024 for a fee of 4 million euros. Despite the difficulties he has faced in Germany, Hong continues to attract attention from various clubs, including some in Belgium and possibly Union SG, although no particular teams have been confirmed.
