Former Ipswich Town player Shane Supple says is "saddened" by Roy Keane's attack on his former team-mate Jonathan Walters and feels that Keane's old-school methods are the reason why the Cork native has not managed a team since 2011.
Supple, who retired from playing at the end of last season with Bohemians, played under Keane at Ipswich where Walters was not only a team-mate but a house-mate.
The former keeper was taken aback by Keane's comments about Walters "crying on the telly".
"I spoke to him this week about what went on. I couldn't believe what was said," Supple said.
"When he's been in the media, it gets very personal. I don't think it's right. I don't know what he does it, why he goes there, why he questions career decisions, their family.
"Johnny has done a lot of good for a lot of people because of what he's come out and spoken about. And I know it doesn't bother Johnny. He laughed about it. It's sad really that someone of Roy's stature feels he has to say something like that."
Supple, who quit soccer to return home when Keane was Ipswich manager, claims that Keane's old-school ways have led to lack of club offers.
"I wouldn't be surprised because of that reason, that approach," he said when asked if Keane may not manage again.
"If you're not adapting to that then certain managers aren't going to last too long. Ruling with an iron fist doesn't work anymore. Clough and these guys, that worked. Men were men. The game has changed so much tactically, you need to be able to see things on the pitch adapt things on the pitch. I don't know if they're right people to go forward. They're not because they haven't had success at club they were at.
"They may have had it 20-15 years ago but as time goes on, different approach needed nowadays."
