And BILD says the 26-year-old's move to Real Madrid is highly likely. The player and his current club have set the March international break as a deadline to discuss his future.
If an agreement isn't reached, Schlotterbeck could be on his way out.
That's where Real Madrid would come into play, as they are a favoured destination for the centre-back whose contract expires in 2027.
If he renews, his salary would rise to €14m annually, and his release clause would be €60m, taking effect in the summer of 2027. It would be €50m if Borussia Dortmund fails to qualify for the Champions League.
