Teenage attacking midfielder Kilian Sauck is being linked with a move from Borussia Mönchengladbach II to Fortuna Düsseldorf, with the switch currently rated at a 59% probability, according to data from Transfermarkt.
The 18-year-old, who plays primarily as an attacking midfielder and is comfortable with both feet, is understood to be on the radar of the 2. Bundesliga side as they look towards longer-term squad planning. Sauck is currently registered with Gladbach’s second team in the Regionalliga West, and any deal would represent a step up from fourth-tier football into Germany’s second division.
Transfermarkt lists Sauck’s current market value at €75k, having risen from €50k in late 2025, a modest figure that could make him an accessible option for Fortuna as they explore lower-risk, developmental signings. With no publicly stated contract expiry date at Gladbach II, there remains the possibility that Sauck’s situation could evolve into a free-agent scenario if no extension is agreed, further fuelling speculation around his future.
Born in Hamburg on 27 March 2007, Sauck holds dual nationality with Germany and Cape Verde. He has progressed steadily through Borussia Mönchengladbach’s youth ranks, moving from the club’s youth setup to the U17s in 2022, then to the U19s in 2023, before stepping up to Mönchengladbach II for the 2025–26 campaign. Earlier in his development he featured for FC St. Pauli’s youth teams and HSV Barmbek-Uhlenhorst’s youth side, giving him a varied grounding in German academy football.
No recent first-team match details or standout performances are recorded in the provided data, but his continued elevation through age groups and recent value increase suggest a player viewed internally as progressing on schedule. Should a move to Fortuna Düsseldorf materialise, it would mark the first transfer of his senior career away from the Gladbach structure and could prove a pivotal moment in shaping his reputation and long-term potential in professional football.
