Roy Keane was hugely critical of David De Gea and Harry Maguire at half-time of Manchester United's draw with Spurs on Friday evening.
Keane told Sky Sports that the Spanish goalkeeper is "overrated" and that he'd be "swinging punches" at him in the dressing room.
Speaking on Talksport's Weekend Sports Breakfast, Keane's former international teammate Tony Cascarino said he believes there is no longer a place in football for the Corkman's approach to the game.
"I watched Roy Keane nearly implode last night on TV, which was typical box office Roy that some people love and others don’t really agree with," said Cascarino.
"Now you know why it wasn’t easy for him to get back into management because when he talks about going for people and players, throwing punches, you cannot talk like that.
"Patrice Evra is laughing at the other side of him, and Keane hasn’t realised there are a number of people within the game who are mocking him because of his behaviour and how he’s speaking.
"He did brilliantly at Sunderland. He turned [them around] with fear. That fear eventually erodes and people aren't so afraid of you, it can then backfire.
"The way he spoke about Harry Maguire, you lose dressing rooms by talking like that.
"If you have a problem with someone and they don’t perform in the way you want them to, like De Gea and Maguire, you leave them out, you just drop them.
"You don’t have to go for them personally, you don’t have to have all that anger towards them, you just make a decision with the team selection.
"But, like we saw last night, Keane just goes after someone and takes it to a new level.
"And, I’m sorry, but there’s no place for that in football.
"Other managers will be looking at that and thinking: ‘No, you can’t be doing that anymore Roy, you just can’t."
“Now you know why it wasn’t easy for him to get back into management.”
“Keane isn’t realising that people are mocking him.”
