Former Manchester United centre-back Rio Ferdinand has admitted that he is 'concerned' by Harry Maguire's lack of pace.
The Red Devils have made more steps forward under head coach Ole Gunnar Solskjaer this season and are currently second in the Premier League table, while they are still in the Europa League and FA Cup.
The 20-time English champions have also kept four straight clean sheets in the league, but Ferdinand has claimed that the lack of pace in the middle of the team's defence is still an issue.
"I think that's Ole's biggest concern - can he leave Maguire one v one on the halfway line? Or [Victor] Lindelof?' said Ferdinand his YouTube channel. "It's proven that you can't as that's not their main attributes. Harry Maguire is good at a lot of other things but that area, that's one of his weak points."
Man United are also currently in talks with Eric Bailly over a new contract at Old Trafford.
