Borussia Mönchengladbach are set to sign Polish defender Jan Leszczynski from Legia Warsaw for a reported fee of €3 million, according to Sky Sport Germany. The 19-year-old centre-back is expected to undergo a medical examination next week, with the transfer contingent on a successful check-up. Should the medical prove positive, Leszczynski will sign a long-term contract with the Bundesliga club.
Leszczynski emerged as a prominent figure for Legia Warsaw throughout the 2025/26 season, demonstrating his capabilities with 52 appearances across all competitions. He quickly became a regular starter in the centre of defence for the Polish Ekstraklasa side, showcasing maturity beyond his years. His consistent performances attracted the attention of several European clubs, but Mönchengladbach moved swiftly to secure his signature.
Borussia Mönchengladbach have been actively seeking to bolster their defensive options ahead of the upcoming season. The team finished mid-table in the Bundesliga last season, conceding 48 goals, and manager Gerardo Seoane identified a need for greater stability at the back. Leszczynski’s arrival is expected to provide competition for places and add depth to the squad.
Legia Warsaw will be losing a key player in their defensive line, but the €3 million fee represents a significant return for a player they developed through their youth system. The club has a proven track record of nurturing young talent, and the sale of Leszczynski will provide funds for further investment in the squad. The Polish club currently sits second in the Ekstraklasa table.
Leszczynski has represented Poland at youth levels and is considered a promising talent with the potential to develop into a key player for both club and country. His move to the Bundesliga will provide him with a platform to showcase his abilities against some of the best players in Europe, and further his development as a professional footballer. This transfer signals Mönchengladbach’s commitment to investing in young, promising players.
