Luke Shaw began his Manchester United career as a full-back of incredible potential who was supposed to be an integral part of the side for a decade.

He was signed for £30 million at 18-years-old - a record fee for a teenager at the time - and his arrival was a part of United's push to return to the top after the disappointment of the Moyes era.

Fast forward three and a half years, however, and Shaw hasn't proven to be what everyone had hoped.

A double leg fracture in September 2015 halted his progress, of course, and by the time he returned to the first team, he found he had a new manager: Jose Mourinho.

Mourinho has never looked happy with Shaw, regularly criticising him for having the wrong attitude and fitness levels, and has even been accused of bullying his player.

Things appeared to have reached their breaking point after the United boss subbed him at half-time in the 2-0 win over Brighton at the weekend and made highly critical comments afterwards that many believed were directed at Shaw.

But despite most feeling that his time at United is already up, the full-back is still determined to prove Mourinho wrong.

The Manchester Evening News is reporting that Shaw is reporting to United's Carrington training ground over the international break - even though players have been given time off.

The extra sessions come at a time when everyone else not involved with their international squads are taking advantage of the break to rest up.

Whether just this alone is enough to sway Mourinho's opinion seems doubtful, but Shaw's attitude certainly goes some way to suggesting that his manager isn't entirely right on this one.

Shaw, still just 22-years-old, clearly has room to improve on the pitch and if the determination is there, surely there can still an opportunity to revive his United career.

Legendary midfielder Paul Scholes is doubtful that he'll get that chance, though, saying after the Brighton match that Shaw won't get what he needs at Old Trafford.

"It's disappointing because when Luke Shaw first came here you thought: 'what a left-back he is, he could be the best," said Scholes.

"It's a relationship that come the summer will end.

"He's just not played many games, just his body shape, he looks like needs to play games."

He might not find the patience at United, but with the talent he's got and the determination he's showing, there will be a host of teams interested in giving him that chance this summer.
