Transfer speculation continues to mount as Darryl Bakola has been linked in recent days with a move to Dortmund. The midfielder, currently playing for Marseille, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. While Stuttgart, Newcastle and Chelsea have shown interest, Dortmund currently lead the race - though the situation could evolve if a deal drags on. So far this season, Dortmund are steady at both ends (1.73 goals scored per game, 0.8 goals conceded per game). The role for Darryl Bakola would be to keep that balance while lifting performances across the pitch. Marseille have also been linked with Lazar Samardzic while Dortmund are reportedly monitoring Kees Smit and Oscar Bobb. Can't get enough Dortmund transfer rumours?
