Nico Schlotterbeck is back on Real Madrid's radar. According to BILD, the 26-team central team of Borussia Dortmund has attracted the attention of six potential buyers, including the Madrid club.

Schlotterbeck is seen as one of the most sought-after central players in the transfer market. Real Madrid have already been a football player before, and now they are again concerned about his situation.

It appears that the German's new contract with the Dortmund club may include a buy-back option to allow him to sign for approximately €60 million.

In this case, the competition for the champion is expected to be serious, and even a number of European top clubs are still showing interest. Schlotterbeck recently returned from injury and is now playing for Borussia again.
