Adnan Januzaj
Januzaj scored twice on his league debut against Sunderland.

Manchester United winger Adnan Januzaj will calm fears over his long-term future at Old Trafford by signing a new contract with the Premier League champions.

The 18 year old scored twice on his full senior debut against Sunderland but with just eight months to run on his current deal a series of high-profile European clubs are understood to be tracking his progress.

Barcelona, Bayern Munich, Juventus and Manchester City are all credited with an interest in Januzaj, who joined United from Anderlecht in 2011.

After Sir Alex Ferguson failed to give the teenager a start during his tenure, new manager David Moyes has wasted little time promoting him into the club's first team with cameo appearances coming against Wigan Athletic in the Community Shield, Crystal Palace and West Bromwich Albion in the Premier League and Liverpool in the League Cup.

But his double at the Stadium of Light has further enhanced his reputation as the brightest young talent to emerge from the United youth ranks, where he won the reserve team Player of the Year award last season, a prize previously scooped by Nicky Butt, Darren Fletcher and John O'Shea among others.

Questions still remain over Januzaj's international allegiance with the youngster eligible to represent Albania, Belgium, Kosovo, Serbia and Turkey, while England are also interested in attaining his services on the basis he remains playing in the Premier League for the next five years, ruling him qualified to play from 2018.

Januzaj has turned down numerous offers from Belgium manager Marc Wilmots to represent the country, the latest proposal coming ahead of the World Cup qualifying double-header against Croatia and Wales.

And while Januzaj, who has trained with the Belgium Under-20 side previously, continues to deliberate over his international commitment, Wilmots says the only thing certain is that he will stay at United.

"He's not made a decision about Belgium, but he's chosen nobody," Wilmots, whose Belgium side are on the brink of qualification for the World Cup in 2014, told Sky Sports News.

"The decision he's made is about Manchester United and then we will see what happens. He's going to stay with United, but not for Belgium or any other country."
