Dortmund have informed Barcelona that they are interested in Marc Casado and are open to including him in a deal for Karim Adeyemi. A €30m asking price has been set for Marc Casado, who is no longer in Hansi Flick's plans. If Casado is included, the deal could almost be a direct exchange of players.

According to Gerard Romero, Borussia Dortmund have expressed interest in Marc Casado as discussions over Karim Adeyemi’s future continue. The German club’s interest in Casado is understood to be linked directly to the Karim Adeyemi Barcelona transfer. Dortmund are reportedly exploring whether Marc Casado could be included in the deal to bridge the valuation gap between the two clubs. Casado is widely expected to leave Barcelona this summer.

Borussia Dortmund has a concrete interest in 22-year-old Spanish defensive midfielder Marc Casadó. Stuttgart and Galatasaray are also reportedly among the clubs with a specific interest. Casadó has a contract with Barcelona for two more years, and his market value is estimated at around 20 million euros. Barcelona is seriously considering selling him, as they are aware they could receive the maximum financial benefit to improve their finances. While specific figures are not currently mentioned, it is possible the transfer could reach an amount similar to the 22 million euros for Antoine Griezmann's return to Atlético Madrid. The Spanish international has 2 caps for his country and has made 20 appearances and provided 1 assist in LaLiga this season for the club he joined in July 2024. According to recent reports from April 2026, there is a range of potential fees, with figures between €20 million and €30 million mentioned in connection with European club interest, and potential offers of around €40 million from Tottenham and Saudi Arabia.
