Rio Ferdinand says his only criticism of Jesse Lingard at Manchester United is a loss of focus he suffered.

Lingard has been in sensational form for West Ham since joining on loan from United in January, having struggled for football under Ole Gunnar Solskjaer.

Speaking on his Vibe with Five podcast, Ferdinand said he has always been a big fan of Lingard but believes he lost focus on the pitch at Old Trafford.

He said: "In terms of pundits on TV, I've probably been his biggest fan.

"He grew up at Man United while I was there, so I've watched him through the years.

"The only criticism I've got of him in that time and since I left is that he might have lost focus off the pitch through family stuff but also through social media, maybe letting that run away a little bit.

"I mentioned it on TV one time but I just feel there was a focus that was lost.

"This kid, talent-wise and ability-wise, I've said for years could play anywhere because he's that good. There aren't many players in the young generation that can play one-touch or two-touch but he can.

"He's got great feet, good body angles to receive the ball and movement to get on the ball.

"He does a lot of textbook stuff that you teach every young player and he gets goals - we knew that at Man United, he scored some big goals.

"I've never doubted his ability, I just think that, no matter how good you are, if your focus isn't 100 per cent on the pitch for whatever reason, then you won't perform to your capabilities.

"He's been a very big proof of that."

Ferdinand believes the attacking midfielder's move to West Ham has enabled him to regain focus and reset himself.

He said: "Now he's gone to West Ham, whether it's being told he can go out on loan and he's thought he needs to reconfigure himself and he's got something to prove, that might be the case.

"You've seen this guy is a top player. He's had to have had some sort of professionalism to turn up there fit after not playing games.

"So his professionalism can't be questioned, it's just sometimes, if your focus isn't 100 per cent, you will not perform to the top of your abilities."
