Manchester United legend Rio Ferdinand has slammed the current crop of players after their humiliating 4-1 defeat to rivals Manchester City on Sunday afternoon.
Ralf Rangnick's side capitulated at the Etihad, a result that leaves them fifth in the Premier League - one point behind Arsenal in fourth having played three games more.
"I feel from the outside looking in, they all just want to be mates," said Ferdinand on his Vibe with Five YouTube channel. "No one wants to put someone's nose out of joint.
"It's like they're all in an office job in the city. They're all being nice and they don't really like each other but they won't tell each other.
"To win, you've got to be pulling people about telling them you're rubbish, sort yourself out. You don't have to be that aggressive either... it can be a simple conversation.
What's Manchester United's biggest problem? Let us know in the comments below!
"Please tell me they are [doing that]. I don't see a response. Their body language is awful, walking about slumped, like the world's against them, looking unhappy.
"You're playing for Man United man, in a derby, do you know how much those fans in that stadium would give to be on that pitch.
"And you're walking around like, 'I could be doing better things than this on a Sunday.' That's the vibe I'm getting from certain guys.
"Fred's an easy cop out, the system didn't suit him at all. We've seen too many managers come and go, it's not about the manager.
"If you're not here to play football, take criticism and improve yourselves every day. If you're not willing to work hard every day, come out of the club."
United season now hangs in the balance, knowing they can't afford to lose their next two games against Tottenham and Atletico Madrid.
Defeat to Spurs would seriously hamper their dying top four hopes, while a Champions League exit would see their wait for a major trophy enter a sixth year.
Ferdinand's comments echo Roy Keane's, as the former United captain was also keen to place the blame on the players' shoulders.
"I don't think the manager could have done too much differently, but by the time the substitutes came on, the fight was over," said Keane on Sunday evening.
"I don't know who's running that dressing room. Look at [Harry] Maguire, he had a poor game. Is he having battles with [Cristiano] Ronaldo for the captaincy and all these things?
"Egos come into it, you leave egos at the front door, these guys are all about, 'How am I looking? Are my boots nice? Is my hair looking good?' Play the game!
"You're at Man United. We were looking at the fans behind the goal and they knew, they're not daft, this team we're supporting have given up.
"We'll hear a load of rubbish over the coming days, and we have heard it before. There will be statements, saying, 'Sorry about that, we'll try it again next week.'
"It's what you do on the pitch that interests me, not all the other garbage."
