Multiple sources today have confirmed that the race to sign Charlie Cresswell is heating up, with Dortmund reportedly submitting an official bid for the defender. The offer is being considered by Toulouse, but it remains to be seen whether it will be enough to tempt them into letting an important player leave. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if West Ham decide to make a formal offer of their own in the coming days. Dortmund's back line has been a real strength this season, conceding just 0.6 goals per game (3 in 5). Charlie Cresswell would be expected to slot into that unit and hold his own in an already solid setup. Reports suggest Dortmund are monitoring Ben Seghir, Axel Disasi and Tyrique George whereas Toulouse have not been associated with other players at this stage.
