Gladbach has accelerated the transfer of Jan Leszczynski from Warsaw – the 19‑year‑old defender signs until 2029 and is set to join the starting XI immediately. The deal was officially announced on June 26 2026, arriving as the Fohlenelf sits in 12th place with 38 points in the Bundesliga midfield.

How did the quick deal happen?

After months of talks between Borussia Mönchengladbach and Legia Warsaw, the transfer fee was set at €4.2 million, according to club spokesperson Anna Müller. The Kraichgau side emphasized that Leszczynski should be integrated into summer training to bolster the back line. Negotiations were reportedly separated from TSG 1899 Hoffenheim, where striker Haris Tabakovic was previously linked.

Why does Leszczynski matter defensively?

Gladbach has conceded 53 goals so far – the worst record since the 2022/23 season. Leszczynski, who contributed three goals and five assists in 28 matches for Legia, is expected to add stability. The young Polish defender is praised for his tackling and positional sense, essential against the league’s top‑scoring teams.

What does this mean for the campaign?

The club sits 51 points behind Bayern Munich and must pick up points to avoid relegation. With Leszczynski, the team could improve its 9‑win, 11‑draw, 14‑loss record. Coach Gerhard Struber plans to slot him straight into the system, aiming to tighten the defense before the next derby against 1. FC Cologne.

What are the next steps?

Leszczynski is expected to attend his first training session on July 2 and could debut on July 12 in the Bundesliga match versus FC St. Pauli. The club also pursues a possible return of Kō Itakura once Nico Elvedi’s sale is finalized. Rumors about Lukas Kirkegaard linger, but the focus now is on quickly integrating the new Polish defender.
