Kevin Boma received two firm offers of approximately 7 million euros from Augsbourg and Paris FC in January, at which time Estoril's management declared him intransferable. In recent weeks, Augsbourg and Paris FC returned with strong arguments and showed continued interest in Boma. However, RB Salzbourg ultimately secured the transfer.

FC Augsburg made an unsuccessful offer for Kévin Boma from Estoril late in the transfer window. The bid for the 23-year-old Togolese international was reportedly worth up to seven million euros. Paris FC also approached Estoril with a similar offer for the central defender, and Besiktas and FC Everton also recently showed interest. Estoril's position was that the player would not be sold during the winter. Boma, who has 10 caps for his country, joined Estoril from Rodez in July 2024 for a fee reported to be €250,000. His contract runs until 2028. In the current 2025/2026 Liga Portugal season, he has made 19 appearances and scored one goal. It was reported that Estoril's asking price was set at approximately €5 million in January 2026. His current Transfermarkt market value is €4.00m.
