Paul Scholes has accused Luke Shaw of not taking care of himself physically but hopes the left-back still has a future at Manchester United.
Luke Shaw joined the Red devils from Southampton in the summer of 2014 for a fee believed to be around £30m, making him the World’s most expensive teenager at the time.
However, the left back has endured a difficult Old Trafford career so far; with injuries and poor form stalling his development.
Meanwhile, former United midfielder Scholes thought Shaw was “the best left-back in the world” when he joined United but the 22-year-old has struggled to break into Jose Mourinho’s first team.
Mourinho gave Shaw a rare start in the Champions League clash with CSKA Moscow, but Scholes feels he is still a long way from his best.
“It’s difficult to say as we don’t see what goes on behind the scenes. I don’t think he lives his life as clean as he possibly should do,” Scholes told BT Sport.
“With his body shape, he looks like a player who needs to be playing every week. We had Wayne Rooney, who was a player if he missed a couple of games you knew, he wasn’t looking after himself.
“He needs to be playing all the time, Saturday, Tuesday, whatever it may be.
“With Luke Shaw, is he going to get a run of 10 games in the team? I’m not sure, the problem he has got is that Ashley Young has been brilliant at left wing-back.
“I hope there is a future for him. A couple of years ago, I thought we were signing the best left-back in the world.”
Meanwhile, United’s manager Jose Mourinho has hailed Luke Shaw, following what he described as a good performance by the defender.
Speaking in his post-match press conference, the boss said: “A very positive performance, especially with the balls going forward. Creating a lot, great intensity in his game. It was no surprise that in 80 minutes he’s feeling the consequences of that intensity; it’s normal as it’s the first match of the season for him. But he’s going to get more.”
The manager added on BT Sport: “He was waiting for quite a long time, he was deserving [of his chance] for quite a long time. It’s not easy to give an opportunity to a player who doesn’t play for many months in matches where the team really needs [a] result.
“I wanted to make changes but changes in players that need a change and not spend a change on Luke. But he managed on for 90 minutes and really I told him this is not the best, this is just an opportunity for you to play and to improve your level. Honestly, I am happy with his performance.”
