Real Sociedad are monitoring Marvin Ducksch's situation ahead of the summer window. The player has a non-promotion release clause worth around €1m, which has alerted a number of interested clubs to his availability. Marvin Ducksch is interested in moving to another club after Birmingham City's disappointing finish in the season.

Real Sociedad has recently inquired about Marvin Ducksch, a 32-year-old German striker at Birmingham City. AEK Athen has also made an inquiry about the forward, and there is interest from the American MLS. Previously, during the winter, two Bundesliga clubs explored a potential loan or purchase, but a departure from England was not a consideration for Ducksch at that time. Ducksch, who has two caps for Germany, joined Birmingham City in August 2025 and has a contract until June 2028. In the current Championship season, he has made 10 appearances, scoring 2 goals and providing 1 assist. His market value is currently €2.00m, according to Transfermarkt. This is the same fee that Birmingham City reportedly paid for his transfer from Werder Bremen in August 2025.
