Manchester United captain Harry Maguire insists they've been their worst enemy this season.

Maguire, who joined last summer from Leicester for £80million, has seen his side miss multiple chances to break into the top four before the season was suspended.

"As a Red, our toughest opponent, probably, is ourselves," Maguire said during a Q&A for MUTV.

"I would say that, at times this year, as a team, we have probably let ourselves down by being a bit too inconsistent. Not just for a full game but during games.

"There have been times when we've been so good in games and then we've come off it a bit and been punished.

"We need to be mentally strong. We are a young group but we don't really want to use that as an excuse.

"We want to be young but play mature. That is where we have really picked up in recent weeks."
