According to the Mirror, the 18-year-old whizzkid signed a new five-year contract earlier this year but now insists he is ready to commit himself to Old Trafford for even longer.
Januzaj, who made his Champions League debut in Tuesday's victory over Shakhtar Donetsk, said that his first opinion was to sign for Manchester United, the report added.
United boss David Moyes has largely been using Januzaj in wide positions, the report further said.
However, the youngster, who was born in Belgium, eventually feels he will move into a more advanced role, the report mentioned. (ANI )
