Borussia Dortmund values their German international defender Nico Schlotterbeck at around 50 million euros, in case the player decides to leave during the upcoming summer transfer window, according to the German newspaper Bild.

Schlotterbeck is considered one of the key pillars in Dortmund's backline, having delivered impressive performances that contributed to the defense's stability before his injury. This has made him a target of interest for several major European clubs looking to strengthen their defensive ranks.

The club management believes that the player still has significant potential for development, especially with his growing experience both domestically and in Europe. This justifies setting a high price for his transfer, given his current contract with the team.

Actual developments regarding Schlotterbeck's future are expected next summer, especially if Dortmund receives offers that meet their financial demands, as the club seeks to balance sporting stability with economic benefits.
