What happened?

Fortuna Dusseldorf officially announced on July 7, 2026 that goalkeeper and captain Jan Kastenmeier is leaving the club. In a press conference Kastenmeier said the decision "was the most emotional" of his career. The 29‑year‑old international has made over 120 appearances since 2020 and has captained the side since the 2023/24 season.

Why does it matter for Dusseldorf?

Kastenmeier's departure means losing a leader between the posts. Without him Dusseldorf must either promote from within or act in the transfer market. Coach Marco Rose stressed that "the squad needs a new voice in goal" to keep the defence solid. Supporters are divided: some applaud his loyalty, others worry about the impact on the league standing.

How does the squad respond?

Training sessions after the announcement showed a focused group. Midfielder Luca Kropf said "the team will stick together and look forward". Meanwhile the club has already opened talks with several keepers, including 24‑year‑old Jonas Müller from a 3. Liga side, who, according to internal sources, is a realistic target.

What comes next?

Fortuna Dusseldorf aims to sign a replacement by the end of July. Sporting director Michael Huber noted that a possible transfer could be finalised in August to avoid disrupting preparations for the 2026/27 season. Fans can expect an official statement on the new goalkeeper on August 15. Until then the defence remains on trial as the team faces SC Paderborn in a friendly on August 12 without Kastenmeier.
