Beşiktaş have signed South Korean forward Oh Hyeon-gyu from Genk in a deal worth around €14 million, with reports in Turkey suggesting the total package could rise closer to €15 million with add-ons. The move was completed on 4 February 2026, and Oh has put pen to paper on a three-and-a-half-year contract that runs to June 2029. He has been handed the number 9 shirt at the Vodafone Park club.
The deal is a direct response to Tammy Abraham's departure from Istanbul for the Premier League. Beşiktaş head coach Sergen Yalçın wanted a similar profile up front, and Oh fits the brief: at 1.87m tall, he offers the physical presence and work rate that Abraham provided as the focal point of the attack. Club sources also pointed to his experience in European football, at both Celtic and Genk, as good preparation for the physical demands of the Süper Lig.
For Genk, it means losing a player who had established himself as their first-choice centre-forward for large parts of the season. Oh joined the Belgian club from Celtic in the summer of 2024 and grew into a regular starter, becoming a reliable focal point in attack before his sale. Losing him for a fee in the region of €14 million represents a solid piece of business for Genk, but it leaves them needing to find a replacement of their own up top.
Oh's form in the months before the move showed why Beşiktaş moved for him. He scored six goals in 20 appearances across all competitions for Genk in the 2025-26 season, including the winning goal against Rangers in the Europa League league phase and his first goal in continental competition in a 5-1 win over Lech Poznań in the Europa League play-off round. His role had fluctuated somewhat after Genk sacked manager Thorsten Fink mid-season, but he remained a regular contributor in Europe.
Before Genk, Oh spent a season and a half at Celtic, where he arrived in January 2023 and scored 12 goals in 47 appearances, winning domestic honours in Scotland along the way. That spell gave him a taste of high-pressure football away from South Korea, and it's the kind of experience Beşiktaş are banking on as he adapts to a title-chasing Süper Lig side with the number 9 shirt on his back.
The early signs since the move suggest he has settled in quickly, with the striker having already found the net regularly in Beşiktaş colours since arriving. For a club that needed an instant like-for-like replacement rather than a long-term development project, that quick return on a player who had already proven himself capable of scoring in Europe looks like a shrewd piece of business.
