The 22 year old Belgian is hot property at the moment and it was understood that United had been chasing the player for some time.
"An imminent agreement with Manchester United? I can confirm that there are informal contacts with Italian, English, French, German and Spanish clubs, but nothing that suggests an imminent closure in a negotiation," Paul Stefani told Calciomercatoweb.
"Still there's not anything concrete so I cannot make names, I confirm that the player is followed by some big clubs.
"A departure in January? It's too early to tell about it, this depends on many things. "
