Fulham are among several Premier League clubs tracking Union Saint-Gilloise defender Kevin Mac Allister. Fulham, Brentford, Leeds United, Coventry City, and Brighton have carried out checks on the 28-year-old Argentine, with Brighton's interest noted due to the club's long-standing knowledge of the Mac Allister family. It has been reported that scouts from English top-flight sides have been in regular attendance at Union matches in recent months. While Mac Allister is under contract with the Belgian club until 2027 with an option for an additional year, the level of Premier League attention could test the club's resolve in the coming transfer window. Mac Allister, who has one cap for Argentina, joined Union Saint-Gilloise in July 2023 for a reported fee of €1.5 million and has a current market value of €10.00m, according to Transfermarkt.
