Manchester United legend Roy Keane slammed the standard of the players after defeat at Liverpool.

Mourinho's team looked lost throughout the encounter and speaking after the game United legend Keane questioned the quality within his former team.

“I certainly believe a lot of the players playing for Man United today aren't good enough for Man United," Keane told Sky Sports. "I really believe that. They are good players, but not for Man United.

"Again you look over the last year or two, the league campaign, to be so far behind the likes of Liverpool, Man City, Tottenham and Chelsea at this moment of time.

"We're on about creativity, but I really think their biggest problem is defensively. You have to try and get some kind of foundation to go forward and were on about scoring a goal, you've got to try keep some clean sheets. They are all over the place.

“I think if Liverpool were really at it today, towards the last 10 and 15 minutes, they could have scored four or five."
