Several clubs, including Basel, Everton, Glasgow Rangers, and Union Berlin, are monitoring Kévin Boma, a 23-year-old Togolese central defender for Estoril. Although Estoril has not yet received any formal offers, Widzew Lodz of Poland was strongly linked with the player but did not proceed due to the financial demands. Estoril is seeking approximately €5 million, while the Polish club intended to offer up to €2 million. For Premier League club Everton, an investment of this nature is considered relatively minor. Basel, alongside Rangers and Union Berlin, had previously made contact regarding Boma last summer, but the interest did not progress at that time. Boma, who has 10 caps for Togo, joined Estoril from Rodez in July 2024 for a fee reported to be €250,000. His valuation is listed on Transfermarkt as €4.00m, and he has made 16 appearances and scored 1 goal during the 2025/2026 Liga Portugal season.
