Gary Neville critical of Manchester United over treatment of Romelu Lukaku

The Belgian recently revealed that he returned from the summer having put on too much muscle over the offseason

Gary Neville has criticised Manchester United's backroom team over their treatment of Romelu Lukaku.

The Belgian international has struggled to recapture the form of a year ago and has been left out in recent weeks with Marcus Rashford preferred up front by manager Jose Mourinho.

He recently revealed that he returned from the World Cup this summer having put on too much muscle over the offseason and that it was hampering his performance.

And Neville is at a loss to explain how that was allowed to happen.

"I struggle with the weight thing and maybe that's just because of how I was as a footballer," he said on Sky Sports' Monday Night Football.

"You could never take a chance with preparation. You could play badly, you could give goals away, you could make mistakes, you could miss chances, whatever type of player you are, these things happen in games. But actually, don't take a chance with preparation.

"Do I turn up every morning? Do I eat the right things? Do I go into the gym at the right times? Do I follow the programme?

"You can argue whether he has got the right programme and then you start to question your coaching staff and things like that, but I really do question that.

"In the modern age when you have 55 staff supporting every team, nutritionists, strength and conditioning coaches, I struggle to understand how a player can be allowed to feel like he has too much muscle or is overweight. Particularly when he's fit."
