According to multiple sources, Chelsea had reached a full, written agreement with AS Monaco to sign the 22-year-old midfielder for a reported €55 million. The transfer seemed to be a done deal, but at the last minute, the news broke that the deal was off. Chelsea is said to be "woedend" (furious) and considers AS Monaco's handling of the situation as "zeer onprofessioneel" (very unprofessional). This is not the only deal that AS Monaco has cancelled at the last minute, as they were also close to selling Folarin Balogun to Everton on Deadline Day, but the American striker remains with the club. Chelsea will now have to look for alternative solutions to strengthen their midfield.
