The Belgian is currently on a season-long loan at Sunderland after failing to hit the ground running at Old Trafford in recent seasons.
Januzaj spent time at Borussia Dortmund last term and he is now trying to find his feet at the Stadium of Light.
But world-record signing Paul Pogba is hoping to reunite with him in Manchester soon.
Pogba and Januzaj became friends at United during the Frenchman's first stint in the Premier League.

Paul Pogba is keen to reunite with Adnan Januzaj at Manchester United
Paul asks if I’ll be back at Manchester United. He wants to play with me.
And the Sunderland winger admits they are still close.
Januzaj told The Sun: “Paul is a great player. He made a different choice but eventually he was successful and he has returned. He remains a great player.
“He’s a very good friend. At United, we were always together. We went to dinner together, played the PlayStation. He was a brother to me.

“Of course, Paul asks if I’ll be back at Manchester United. He wants to play with me. But I am now at Sunderland and I have to do what’s right for the club.
“These are decisions from above. I’m a professional footballer and I have to remain professional and work.”
Januzaj has made 17 appearances for the Black Cats this season, netting one goal in the EFL Cup against Shrewsbury back in August.
