Shaw was 18 when he swapped Southampton for Old Trafford in June 2014 for a fee thought to be £30million, a record transfer for a teenager at the time of his move.

He has had a chequered time in the north west, with a serious injury, form and fitness issues limiting him to 50 Premier League appearances in nearly four and a half years.

The 23-year-old has also faced public criticism from manager Jose Mourinho and was linked with a move away from the club only a few months ago, though he has become a regular under the Portuguese this season.

Shaw's contract was set to expire at the end of the summer but he has now committed his long-term future to United.

He said on the Manchester United app: "If you look at my situation in the last year and a bit, you'd have thought this could have been impossible. But I worked hard, I wanted to be here and I wanted to make sure my future was here to help this club."
