Manchester United Treble winner Jaap Stam says Harry Maguire has suffered from a change of system this season.

The Dutchman does not believe Maguire is the only one to blame for the problems at the back.

“Harry can do better than what he's been showing for the club, because this manager is asking things of him that maybe he's not always used to," Stam told safebettingsites.com. “That takes a certain time to get the confidence in doing so and having that self-belief to perform better.

“Now, United are playing with one holder instead of two, that makes it more difficult as well, and easier for the opposition to press. These are things that can help Maguire out.

“It's important the players alongside him, but also in front of him, the midfield players, are helping him out, and giving him the right options.

“Dalot on the right side, he needs to help Maguire out as well by taking up the right positions. A lot of times, that's not helping him.

“Defensively, sometimes he's [Maguire] making decisions that are not the correct ones. But that's also true for a lot of players around him."
