The summer signing from Southampton has failed to produce his best for Manchester United so far.
This summer Manchester United made Luke Shaw the most expensive teenager in the world, spending £27 million to bring him in from Southampton.
The club were to sell both Alexander Buttner and Patrice Evra in the summer, so the arrival of left-backs was key. Daley Blind and Marcos Rojo also arrived, but Shaw was undoubtedly the player they wanted to shine in the position.
But it has not been plain sailing for him early on at United.
He struggled with injuries after his World Cup exploits and fitness has also been a concern. In the recent game against former club Southampton Shaw struggled to get the better of Nathaniel Clyne and was eventually subbed off.
This has seen many a doubter for Shaw, but at least he has the backing of one former United full-back. United legend Dennis Irwin played over 500 games for United in a 12 year career, mostly at left-back.
And he told United Review that he is backing Shaw to be a big success going forward:
"He had a whirlwind two months when he signed for us after playing at the World Cup, which is a lot to take on for a 19-year-old. It took him a while to settle and realise what the club is all about, which is why pre-season is a good time to sign players.
“Injuries held him back a bit but once he got in, he looked really strong and don’t forget he is only a boy. He has been very unfortunate with injuries, but he will be a fantastic player for us. I guarantee you that. I have no doubt at all that he will be our first-choice left-back for years to come...
Luke Shaw will be a top player for United, make no mistake.”
Those words of encouragement, from a player who has seen it all and done it all at United, will certainly be a big boost for the young defender in his quest to live up to his lofty price-tag.
