Rio Ferdinand has named the Manchester United star who needs to work on his game to fit under Ralf Rangnick following the club's underwhelming performance against Young Boys in the Champions League.
The Red Devils, who were already confirmed as group winners, failed to impress in their 1-1 draw with Young Boys on Wednesday.
Rangnick fielded a second-string side, with the likes of Donny van de Beek, Juan Mata and Jesse Lingard starting at Old Trafford.

Aaron Wan-Bissaka was also given a run out, with his outing singled out by Ferdinand who believes the right-back needs to work on his game with the ball.
The 24-year-old has recently lost his place in the side to Diogo Dalot, with the BT Sport pundit stressing the importance of full-backs in today's game.
"I don't think anyone other than Mason gave Ralf something to think about," he said.
"I just feel with Wan-Bissaka he needs to work on his game with the ball. Full-backs today are controllers of the game. No.8s, midfielders were always the conductors."


Ferdinand continued: "Nowadays, the players who are getting most touches are the full backs.
"So, you have to be good at receiving the ball and playing it over various distances and adding different layers to your game.
"In Wan-Bissaka if you are talking about the top right backs in the country, that's where he falls short.
"What is there for him, he can see it. You know what you need to work on. It is clear for all to see. That is what the manager needs and that's what the managers wants.
"He must now thinking, 'right, how am I going to going to enable myself to be able to execute in those situations.'
"That comes with repetition on the training ground and working on the pitch and the coaches."

Unfortunately for Wan-Bissaka, he was stretchered off in the second-half following a collision with the advertising hoarding.
The former Crystal Palace youth product was a regular under Ole Gunnar Solskjaer, but he'll need to impress the German to regain his spot in the XI.
Rangnick, meanwhile, will assess the player's fitness ahead of potentially picking him for Saturday's Premier League clash against Norwich.
