Rio Ferdinand has questioned Harry Maguire's captain credentials by suggesting Man Utd are "suffering" from a lack of any real leadership.
Maguire has held the armband at United since the start of last season, while Bruno Fernandes recently stepped into the role in his skipper's absence against PSG.
But Ferdinand feels neither player has shown the qualities necessary to take United forward.
Ferdinand told BT Sport : 'We were there the other day watching this game [West Brom]. It's not just about Ole on the sidelines, or Mike Phelan or Michael Carrick talking on the sidelines, but sometimes you need a player.
"Bruno, who you don't mind giving the ball away because he is the creative spark right, but he gave the ball away very cheaply probably about four times before half-time.
"I am sitting there looking around the team thinking who is going to be onto him? Who is going to be telling him? I would have been screaming."
BT Sport presenter Gary Lineker then quizzed whether Maguire or Fernandes were up to the task.
"I don't think they are to be honest," Ferdinand responded. "If you are being brutal, I don't think any of them have shown any signs.
Who should be Man Utd's captain? Have your say below.
"Maybe Bruno - a new player coming in and taking responsibility in interviews, and on the pitch you can see he demands the ball and takes responsibility that way - but I don't see anybody who is going to ruffle feathers or pull someone aside and say 'listen, you have given possession away cheaply the last three times, sort yourself out'."
He added: "Having no fans in the stadium is disgusting and we hate it but it has opened my eyes to see that there aren't many leaders playing football at the moment and Man United are suffering from that."
