Manchester United legend Wes Brown has been very impressed by central defender Eric Bailly.
The Ivory Coast star has endured significant injury problems with the Red Devils in the past few seasons.
But he has got a run in the team this term, and has not let down manager Ole Gunnar Solskjaer.
Asked about Bailly and United's defence, Brown told Stadium Astro: "United's defenders this year have done well.
"They started the season badly, with some bad individual mistakes, but since players have started coming back and challenging for positions, I think it has upped everyone's game a little bit.
"[Alex] Telles coming in has upped Luke Shaw's game, Bailly coming back and getting a few games has upped Lindelof's game.
"Harry Maguire you would say starts every game if he is fit, but Eric Bailly now has made it difficult for Ole [Gunnar Solskjaer] in the sense that if he keeps on playing like that then he might have to keep him in for a while.
"I love competition and I think that is one thing that got dug into us."
