“He’s not rolled up his sleeves and even with as much courage as Roy Keane says he’s got, this is the end for him.

“He’ll not manage again.No-one will give him the opportunity to manage a football club because they won’t trust him.That’s the bottom line.

“Up until the last few weeks where it’s gone pear-shaped and he’s not had the results, I thought he’d done a good job.

“But they are only two wins away from mid-table.

“You’re going to have bad results in your management career as you do in your playing career. But you don’t just walk away.”

Cascarino also doubts Keane ever united the dressing room, citing what he believes is the former Manchester United’s lack of communication.

“What amazes me about Roy, and I’ve shared many dressing rooms and played lots of matches with him, is that he would be very insular about the way he felt and very rarely said things like he says via the media, and that’s very strange for someone who says they are very honest.

“He never said things in the dressing room, very little came from Roy, he didn’t have friendships, he didn’t care and ultimately his dealing with people has been his downfall.

“Knowing Roy, he’s never had a dressing room.

“He’s never had anybody on his side because he wouldn’t get that close to people.

"

Asked if he thought Keane had taken the easy way out, Cascarino continued: “Yes I do.He instigated the problems in Saipan in 2002 and he got away.

“He instigated the problems towards the end of his time at Manchester United by criticising the players in an interview on MUTV.

“He instigated the problems last Friday to do with his present team and the doubts around himself and I think it was all to open for the door to walk away.

“Maybe he doesn’t want to face Fergie; maybe he doesn’t like the fact that Fergie might stare him down and give him his comeuppance.”
