WHO WILL WEAR JERSEY NUMBER 11 AT MANCHESTER UNITED.?

At Manchester United the jersey number 11 was worn for many years by the famous Welsh winger Ryan Giggs. He is the most decorated footballer ever, so I strongly felt that Manchester United should have retired that famous jersey number 11. As it was done in Italy with their famous club A.C.Milan , who retired the jersey worn by their great defenders Franco Baressi and also Poulo Maldini. But the jersey number of Maldini is not retired for good, it will now be worn by his son who is training at the A.C.Club youth academy. But what manchester United have done is they have given jersey number 11 to Adnan Januzaj, but what happened to the number he wore last year at Manchester United.
