The former footballer did not hold back with his critique after Solskjaer's men were torn apart by their bitter rivals.

It must not be an easy thing to be a Manchester United fan after losing this Saturday's derby, and some of the former Red Devils made sure that their current players share some of that embarrassment with their analysis of the game.

Speaking right after the game, Sky Sports' pundit and former midfielder Roy Keane blasted the team's poor performance against their bitter rivals by pointing out that their lack of consistency and commitment resulted in one of the worst displays he has seen from the team led by Ole Gunnar Solskjaer, especially when talking about home games.

"Manchester United is such as disaster that it's hard to believe. This place (Old Trafford) used to be a fortress, it was hard to come here. Now, you should ask Everton, or Aston Villa and Liverpool. In the end, what you get when you play at home sets the grounds to compete for the trophies," Keane stated.

Keane continued his attack against the Red Devils by judging their lack of intensity in such a big game.

"This was even worse than Liverpool despite the final score. The difference in class, quality, decision-making...everything," Keane added.

In his next intervention, Keane singled out three players as the most disappointing of the lot that faced Manchester City earlier today.

"That second goal killed the game. I don't know what to say, it was a really poor display. (Scott) McTominay or Fred are not the kind of players Manchester United should have. The first goal? I was not surprised, since (Eric) Bailly is such an erratic footballer," Keane concluded.
