Chelsea legend Frank Lampard feels Manchester United midfielder Paul Pogba needs to improve the defensive aspect of his game.

Writing in the London Evening Standard, Lampard declared: "I'm a bit confused about all this talk regarding Pogba's position. I understand Mourinho's point when he explained he's a midfielder that can play in two positions.

"I don't think he's a No.10. He doesn't have the goal tally to play there or to be given a free role - that has gone in the modern game.

"But whether you are picked to play in a two-man midfield or three, you have to have defensive discipline, particularly in big games in the Champions League or away to a team like Tottenham at Wembley.

"I used to play in a three-man midfield mostly, but I was also in a two for the last few years of my time at Chelsea and throughout my England career.

"You know when you go into a bigger game that you have to have extra discipline because of what your opponent can do to you.

"So no-one can switch off or have moments out of position. It will damage the team.

"Pogba has to recognise that because he has moments of amazing ability on the ball. He just has to learn that defensive side of the game."
