Union Berlin Secures Belgian Centre-Back Zeno Van Den Bosch on Free Transfer
Union Berlin’s defense just received a new spark. On Monday, June 11 2026, the Bundesliga club announced that it has signed 22‑year‑old Belgian centre‑back Zeno Van Den Bosch from Royal Antwerp. The move comes on a free, after Van Den Bosch’s contract with Antwerp expired. The 22‑year‑old completed a medical with Union before the deal closed, allowing the club to add a seasoned defender without a transfer fee.
Van Den Bosch rose through Royal Antwerp’s youth ranks before earning a first‑team spot in 2022. Since then he has appeared in 140 competitive matches, scoring a handful of goals and earning a reputation for composure under pressure. The defender has also represented Belgium at under‑21 level, showcasing his potential on an international stage. His experience in the Belgian Pro League and in European competitions, including the UEFA Europa Conference League, provides him with a breadth of exposure that is rare for a player his age.
Since its promotion to the Bundesliga in 2019, Union Berlin has been intent on fortifying its back line. The club’s recent transfer window activity has focused on adding depth and stability to a defence that has been exposed during tight matches. Coaching staff have highlighted the importance of a solid centre‑back partnership as the team prepares for the 2026‑27 season, where the competition will intensify. By bringing in a defender with over 100 competitive appearances, Union aims to blend experience with youthful energy, ensuring that the back four can absorb pressure and maintain composure in high‑stakes games.
Royal Antwerp, founded in 1880, is Belgium’s oldest professional club. The team’s 2022‑23 campaign saw a domestic double, and it secured a spot in the 2023 UEFA Champions League group stage, a rare achievement for the club. Van Den Bosch’s departure follows Antwerp’s decision not to offer him a contract extension, allowing him to leave on free terms. The club’s choice to let the young centre‑back walk away reflects a strategic shift towards a younger squad and a different defensive profile for the upcoming seasons.
The announcement on Union Berlin’s official website confirmed that the defender’s contract with Antwerp had run its course and that the club had agreed on personal terms with the 22‑year‑old. No transfer fee was exchanged, and the club chose not to disclose the length or financial details of the new contract. Tactically, Van Den Bosch is expected to vie for a starting spot in Union’s centre‑back pairing. Current options include a mix of experienced internationals and younger domestic players, and the addition of a Belgian international with European experience is intended to broaden the squad’s options and provide mentorship to younger defenders. Union will monitor his integration during pre‑season training, hoping the move strengthens the back line for the upcoming Bundesliga campaign.
With Van Den Bosch on board, Union Berlin signals its commitment to a defensively resilient squad capable of challenging Germany’s elite. The club’s management views the free transfer as a low‑risk acquisition that bolsters the squad without stretching the budget. As the pre‑season camp progresses, coaching staff will assess how the new centre‑back meshes with teammates and whether his experience can translate into a cohesive partnership at the heart of the defense. The 2026‑27 season will test the depth of Union’s back line, and the addition of a seasoned Belgian international is expected to provide a stabilising influence as the club seeks to maintain its Bundesliga status and pursue higher ambitions.
