The 18-year-old has impressed for the Red Devils this season, making two Premier League appearances, but his current contract with the Old Trafford outfit expires in 2015.
After initial talks stalled falling the legendary Scot's departure, Januzaj's representative, Dirk de Vriese, is keen to re-open negotiations, though says there are a number of clubs interested on acquiring his services.
"I’m not going to say which teams are interested in him, but I can tell you that there is interest from several European clubs," De Vriese is quoted as saying in an interview with Voetbal News.
"The departure of Sir Alex Ferguson meant that there was a break in the negotiations. We are back working on the calls and will see how it goes.
"Adnan’s family have given me the permission to communicate. As it is only me involved, there can be no misunderstandings in the media."
Januzaj is eligible to play for four different countries, including Belgium, Turkey and Serbia, and De Vriese says the youngster will weigh up his options before electing to decide on the nation he will reprsent.
"Januzaj’s father has always been clear about his future as an international. He must have a starting spot somewhere and then he can decide from there," De Vriese added.
"There have already been sent many e-mails and faxes from the respective bodies to inquire about his future. In Albania there are even entire television shows about him that have been organised to convince him to choose their national team."
