Manchester United midfielder Adnan Januzaj has penned a new five-year deal that ties him to the English Premier League champions until June 2018.
Januzaj played a starring role in his first competitive start for Manchester, scoring two goals in his side's 2-1 victory over Sunderland a fortnight ago.
"It's a great thrill to be able to sign for Manchester United," the Belgium-born player told the club's website.
United manager David Moyes told the club's official website: "I'm delighted that Adnan has committed his future to United
"He is an outstanding talent and has impressed me consistently since I came to United in July.
"His balance, poise and ability to beat players is truly exceptional for a boy of his age. It's great that he recognises that this club, with its tradition for developing young players and giving them a chance on the biggest stage, is the best place for him to be."

The 18-year-old's contract was due to expire in the summer, and he could have left Old Trafford for a minimal fee.
"It's like a dream," added Januzaj, who excelled in United's youth and reserve teams after joining as a 16-year-old.
"Since arriving here I have always felt like this was the right club for me."
