Former Manchester United midfielder Roy Keane believes Louis van Gaal's current side are "lacking some characters" after they slipped out of the Champions League on Tuesday night.
United were beaten 3-2 by Wolfsburg, conceding some sloppy goals, and Keane was scathing in his assessment of a side that spent over ?100million during the summer and will now drop into the Europa League.
The Irishman, who was a studio pundit on ITV's Champions League highlights show, said: "(It's a) disaster from last night really, considering the goals they gave away.
"I think Manchester United have a lot of good players, there's no getting away from that, but I don't think they are good enough for Man United.
"I think they lack real quality, you look at the recruitment, they have thrown decent money at it, but there are no special players at the moment.
"Think of Manchester United and you've always associated one or two special players who can produce. They seem to be lacking a few characters, a few leaders.
"You can look at the goals they conceded - their league form hasn't been too bad, they've kept plenty of clean sheets, but they are certainly lacking some characters."
Keane believes Van Gaal should not shoulder all of the blame, adding: "The manager is getting a lot of criticism and the players are hiding behind that and people are talking about tactics and systems but it's about the players as well.
"The goals they conceded on Tuesday night were from set-pieces. That's not about tactics or systems, that's about doing your job.
"They are almost robotic - display a bit of passion, desire. They are Manchester United players, show a bit of character.
"Michael Carrick, the guy just walked off the back of him (for the third goal), an experienced player. Get a hold of him and say 'we are not conceding'.
"Okay, I know they would love to win the game, but make sure we don't lose it.
"I just think sometimes managers get too much credit when things are going well and they get too much criticism when things aren't going so well.
"There are a lot of experienced players in the team, (Bastian) Schweinsteiger, Carrick, the goalkeeper (David de Gea), experienced international players, it's up to them to help the younger players."
