Leeds United are among several Premier League clubs tracking Union Saint-Gilloise's 28-year-old Argentine defender Kevin Mac Allister. Other top-flight English sides, including Brentford, Fulham, Brighton, and newly promoted Coventry City, have also carried out checks on the player, who has one cap for Argentina. It is understood that scouts from Premier League teams have been regularly present at Union's recent matches to monitor his progress. Mac Allister is under contract with the Belgian club until 2027, with an option for an additional year, but the growing attention from England could challenge Union Saint-Gilloise's resolve to retain him in the next transfer window. He joined the club from Argentinos Juniors in July 2023 for a reported fee of €1.5 million, and Transfermarkt estimates his current market value to be €10.00m.
