Adnan Januzaj's burgeoning potential at Manchester United has been rewarded as he was given Ryan Giggs' iconic No.11 shirt ahead of the new season.

Despite calls from supporters to retire the shirt following Giggs' retirement at the end of last season, Januzaj will wear the number for the new campaign after enjoying his breakthrough campaign at Old Trafford last season.

The 19-year-old – who won a call-up to the Belgium squad for the World Cup finals in Brazil – scored four goals in 27 Premier League appearances last term and was a rare highlight during a disappointing campaign for United.

Having only played 14 minutes during pre-season after Belgium reached the quarter-final of the World Cup, Januzaj is not expected to feature in Louis van Gaal's first game as manager in the Premier League opener against Swansea City this weekend.

However, after being handed such a prestigious number ahead of the new term, Van Gaal has given a huge indicator over the role Januzaj will play this season and United's faith in the youngster to fulfil his potential.

Coach Phi Neville wrote on Twitter: "Januzai given the number 11 shirt -massive act to follow but one I'm convinced he can handle he is going to be a great player!"

New signings Luke Shaw and Ander Herrera will wear the No.3 and No.21 shirts next season but a number of high-profile numbers remain curiously vacant with over two weeks of the summer transfer window remaining.

Antonio Valencia has vacated the No.7 shirt and reverted to his No.25 shirt while the No.5 and No.15 jerseys lefts by Rio Ferdinand and Nemanja Vidic have also been unfilled. United also remain without a No.9 in their first team squad.

United dropped a potential hint over their remaining dealings in the transfer window, but writing on Twitter: "Please note: any new acquisitions will be handed shirt numbers that are currently vacant."

Van Gaal has hesitated over making significant changes at United as he continues to assess his current squad but has made no secret of his desire to sign a defender, with a deal for Argentina's Marcos Rojo reportedly in the offing.
