Dwight Yorke has taken aim at former Manchester United teammate Roy Keane.
Yorke says Keane, as a pundit, should remember he made mistakes as a player, too, and that this tendency to fly off the handle was one of his downfalls as a manager.
"I know what he's like," said Yorke, who played under Keane at Sunderland. "He says what he likes to say. Some people buy into it, some don't.
"We all make mistakes. He wasn't perfect when he played. He made mistakes along the way. He has to tone that back a little bit. Maybe one of the downfalls which I recognised from his management career is that the way he delivered his approach to players could be quite offensive.
"Brian Clough, Ron Atkinson, maybe even Sir Alex Ferguson sometimes, they give those kind of rollickings. Players of yesterday could easily dust those kind of comments off.
"Things have changed. It's the way you go about it which is important and that's one of Keane's problems: he doesn't know how to deliver it."
