It seems as though José Mourinho might have just about put the final nail in Luke Shaw's Manchester United coffin.

Mourinho has seemingly criticised the left-back, who joined the club for £30m in 2014, ever since he walked through the doors at Old Trafford.

Having been the most expensive teenager in the world at the time, his lack of progression and struggles with fitness have been largely disappointing, albeit he did suffer a horrific leg break in the Champions League in 2015.

It's fair to say that the Portuguese has exhausted all manners of dealing with Shaw though, giving him both the cold shoulder and a pat on the back to try and coax his ability out of him.

The former Chelsea manager even claimed there were very few better players in his position in world football after a string of improved performances around the turn of the year.

"I'm really happy and [looking at the transfer market], I can say that in this moment I don't see many left-backs better than this Luke Shaw," he said at the time, but things couldn't be more different now.

Mourinho was pretty disgusted with his display in United's 2-0 win against Brighton in the FA Cup quarter final, and couldn't hide his anger, dragging the former Southampton man off at half time.

After the game ended, he slated his defensive showing, which can't have done wonders for the 22-year-old's confidence.

"To try to improve our offensive football and be more aggressive I had to change one of them and I decided Luke, because at least Antonio defensively was capable of good positionings," he started.

"Luke, in the first half, every time they went in this corridor, the cross was coming, the situation was coming so I was not happy with the performance."

After reports of a subsequent training ground bust-up, Shaw's representatives have indicated he will consider his future at the club at the end of the season.

The Englishman has a year left on his contract, but if Mourinho has anything to do with it, he'll be out of the door come the summer.

That's according to the Sun at least, because they claim that the two-time Champions League winner has already identified a replacement for Shaw.

And that man is Fulham's 17-year-old wonderkid Ryan Sessegnon.

Originally a left-back, he has shown he is equally as capable on the wing, notching 14 goals and adding five assists in 38 games.

He has featured in every single fixture for the Cottagers this term, and has been a major part of their excellent form which has them right on track for a return to the Premier League next term.

Sessegnon has just been called up to the England under-21 squad, though there have been plenty of calls for him to make the senior group for the World Cup this summer.

A fee of around £40m could be enough to secure his services, though United will have plenty of competition for his signature.

One thing is pretty clear though; Shaw's days at Old Trafford are numbered.
