Transfer interest is building around Nico Schlotterbeck, with Real Madrid understood to be weighing-up a move for the Dortmund defender. While there has been no official bid as yet, the club may act swiftly if they decide to pursue the deal before the transfer window slams shut. Bayern Munich may look to intervene if talks continue without resolution. Real Madrid's back line has been a real strength this season, conceding just 1.14 goals per game (8 in 7). Nico Schlotterbeck would be expected to slot into that unit and hold his own in an already solid setup. Reports suggest Real Madrid are monitoring Florian Wirtz, Moises Caicedo and Kees Smit whereas Dortmund have not been associated with other players at this stage.
