Luke Shaw's season marks a first for him in a Manchester United shirt as the fullback started in all 38 games in the Premier League with no interruption from injury. 

Shaw remained a reliable asset in United's squad, despite facing turbulence from the dismissal of Rúben Amorim and the transition into the Michael Carrick era as the Red Devils achieved a third-place finish in the Premier League.

Many fans called for the 30-year-old's inclusion in Thomas Tuchel's World Cup squad; however, Shaw was left out in favour of Nico O'Reilly, Djed Spence and Tino Livramento as the left-back options.

Tuchel also surprisingly left out Harry Maguire, who had been a staple piece of the England defence under Gareth Southgate as well as being a leader within the squad.

Former England international Kyle Walker has made his opinion of Tuchel's decisions clear as he believes Shaw could have played a crucial role in England's attempts to secure their first World Cup title since 1966.

Speaking on TalkSPORT, six-time Premier League-winning fullback Kyle Walker shared his honest views on the exclusions of Maguire and Shaw.

He stated: “That one shocked me [Dan Burn] especially over Harry Maguire.”

“I think people forget Luke Shaw. Luke Shaw’s had a fantastic year for Manchester United.”

“To be in the tournaments that Luke Shaw has been in as well. And okay, probably he’s not got the legs of Djed Spence or Livramento, but his experience and you could probably sit him next to the centre halves and let Reece James go a little bit higher.”

Versatility seems to be a crucial aspect of Tuchel's squad selection, with the likes of Burn, Livramento, O'Reilly and Spence capable of operating in multiple roles across the backline. 

However, Luke Shaw has demonstrated his ability to cover through his stints as a left-sided centre-back in Rùben Amorim's 3-4-2-1 system, as well as an emergency centre-back in a back four when United has faced major defensive injury issues.

Shaw has proven his ability to perform in an England shirt, providing one of the highest highs in recent history, scoring in the opening two minutes of the 2020 Euros final against Italy as England narrowly lost on penalties.

Shaw has been a part of the England set-up since 2014, when he made his World Cup debut and after a plague of injuries, made his way back into a major tournament selection in Euro 2020.

Club performances at Old Trafford have certainly proven Shaw's capabilities, excelling in technical ability, physicality and tackling. Shaw's intelligence on the pitch could be an aspect that England misses with Tuchel selecting a particularly young squad.

England's first World Cup game comes against Croatia in Dallas, Texas, on Wednesday, June 17th, at 9 pm BST (3 pm local time). Expectations are high for Tuchel after being brought in with the goal of bringing football home.
