Senegalese forward Kaly Sene, 25, struggled from the beginning at Middlesbrough. Under Hellberg, he did not appear suited to the style and struggled to have an impact in his limited appearances, scoring two goals in 28 Championship games in the 2025/2026 season. A departure this summer is likely to be suitable for all parties. Sène, who joined the club in August 2025, has a contract until 2029. According to Transfermarkt, his current market value is €2.00m.
