Borussia Mönchengladbach are poised to secure the signature of teenage defender Leszczynski from Legia Warsaw. The Bundesliga club are expected to pay approximately €3 million for the 19-year-old centre-back, who is scheduled to undergo a medical examination next week before completing his move to Germany.
The Polish youth international enjoyed a breakthrough campaign during the 2025/26 season, establishing himself as a key figure for the Polish capital side. Leszczynski made 52 appearances across all competitions, cementing his place as a regular in the heart of the defence and demonstrating his readiness for top-level football.
Deal structure
According to Sky Sport Germany, Gladbach are finalising the transfer ahead of the defender’s arrival. The deal will see Leszczynski commit to a long-term contract with the Bundesliga club, though specific terms and duration have not been disclosed.
The €3 million fee represents a significant investment in young defensive talent for the German side. At 19, Leszczynski brings both immediate squad depth and long-term potential to Gladbach’s backline as they look to strengthen their defensive options for the upcoming campaign.
Medical and completion
The transfer hinges on the successful completion of Leszczynski’s medical, which is pencilled in for next week. Should the examination proceed without issue, the club are expected to announce the signing shortly thereafter, adding the Polish teenager to their roster.
The move would represent a significant step in the career of the Poland youth international, who has established himself as a regular starter despite his age. His departure would leave a notable gap in Legia Warsaw’s defensive ranks following his consistent presence throughout the previous campaign.
Gladbach’s acquisition of the young centre-back underscores their strategy of investing in emerging talent from the European market. The defender’s extensive experience at senior level suggests he could adapt quickly to the demands of Bundesliga football.
