Manchester United legend Roy Keane put forward a blistering attack on Bruno Fernandes.
The Portuguese, who is United's current club captain, has been eviscerated by one of its most successful skippers ever.
Keane was not impressed by Fernandes nor his teammates in a 3-0 loss to Manchester City in the derby on Sunday at Old Trafford.
After the league clash, Keane said on Sky Sports: "After today and having watched him again I would definitely take the captaincy off him. 100 per cent.
"I know it's a big decision, obviously he changed the captaincy with [Harry] Maguire, but Fernandes is not captain material."
Keane continued: "I think he's a talented player no doubt about it.
"But what I saw from him today; his whinging, his moaning, he's throwing his arms up in the air constantly, it really isn't acceptable.
"And what we saw today, I would take it off him.
"Cause we're talking about making changes, you have to start somewhere whether it's board level, managers, I would start with that because the manager is capable of doing that and holding his hands up and saying 'listen I got it wrong'.
"In terms of captain material, he's the opposite to what I would want in a captain."
