A February report identified Brentford as one of several international clubs, including Chelsea, Brighton & Hove Albion, Inter Milan, AC Milan, and Como 1907, showing interest in Mainz 05 defender Kacper Potulski. More recently, former player Tomasz Hajto claimed that German clubs such as Borussia Dortmund and Bayer Leverkusen are also interested in the 18-year-old. This interest has emerged amid reported frustration from the player's camp regarding his inconsistent playing time at Mainz. He is under contract with the club until 2028, and his deal reportedly contains no release clause.
