Multiple sources are reporting an imminent transfer move for Abdelhamid Ait Boudlal, with Dortmund reportedly showing interest in the defender currently plying his trade at Rennes. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Dortmund remain optimistic, but the deal is not without hurdles. Metz and Lorient continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Dortmund's back line has been a real strength this season, conceding just 1.0 goals per game (29 in 29). Abdelhamid Ait Boudlal would be expected to slot into that unit and hold his own in an already solid setup. Dortmund have recently been linked with Ibrahima Ba, Diego Moreira and Jadon Sancho while Rennes have had no rumoured targets. More on this story as it develops. Need more Dortmund transfer rumours?
