Former Manchester United full-back Paul Parker has claimed that Luke Shaw is the weak link in Ole Gunnar Solskjaer's defensive unit at Old Trafford.
Shaw was voted United's Players' Player of the Year and Sir Matt Busby Player of the Year for the 2018-19 campaign after enjoying his most productive campaign for the club.
The 24-year-old faced criticism from former boss Jose Mourinho during the clash with Chelsea last weekend, though, and now Parker has questioned whether the Englishman has really "kicked on" at the club.
"I felt really sorry for Shaw under Jose Mourinho. He didn't deserve what Jose gave him. Mourinho should have been helping him especially after suffering such a horrific broken leg," The Mirror quotes Parker as saying.
"But I don't think Shaw's helped himself, either. He should have been on the best diet and fitness regime in the world to prove himself but he's not. He's just not kicked on in the way I'd have hoped. He's a throwback defender from my era and when he goes forward there's not enough variety to his game.
"He doesn't do anything different. He can't beat people, he hasn't got a trick with the ball at his feet. It's a push and run or a ball in behind for him to run on to.
"I understand what Mourinho was saying the other day against Chelsea in that [Harry] Maguire will have problems covering for Shaw who sometimes goes missing."
United will be looking to build on their 4-0 victory over Chelsea last weekend when they travel to Wolverhampton Wanderers on Monday night.
