Transfer interest is building around Nico Schlotterbeck, with Barcelona 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. While Barcelona and Dortmund continue talks, no breakthrough has been reported. Man Utd, Liverpool and Real Madrid reportedly may still have an interest, but currently the focus is on getting this deal across the line. Defensively, Barcelona are sitting around the league average this season, at 1.25 goals conceded per game. Someone like Nico Schlotterbeck could keep them steady but also raise the level when it matters most. Alongside this, Dortmund are said to be exploring Said El Mala and Fisnik Asllani with Barcelona likewise connected to Lautaro Martinez, Bruno Fernandes and Nathaniel Brown.
