Former Chelsea fullback Glen Johnson has mocked Manchester United captain Harry Maguire ahead of today's big game.

Blues manager Frank Lampard takes his new-look Chelsea side to Old Trafford for a crunch showdown with United, who will be flying high after another famous win at PSG in midweek.

United captain Maguire missed that match due to a muscle injury but could return to play Chelsea.

"If I'm Timo Werner, I'd be like, 'Please play [Maguire]!', I really would," Johnson told Optus Sport.

"I think he would be an absolute nightmare for him.

"But I agree, in the bigger picture, it's hard to leave your captain out and obviously he's a big player for them.

"But on that last performance, if I'm [Axel] Tuanzebe, I'd be thinking: 'Why aren't I playing?'."
