Roy Keane has been told he goes 'overboard' when criticising players he manages.

The Manchester United legend has not been a senior coach since leaving Ipswich Town in 2011.

Celtic are reportedly considering the Irishman to become their next manager.

And Carlos Edwards, who played under Keane at Sunderland and Ipswich Town, hopes Keane has learnt from his management exile.

He told TalkSport: "I got a few b******ings for messing up in games and causing a few goals, but I never got the brunt of it.

"Roy had his moments when he let a few steams out, which is understandable.

"He went overboard at times, but as a player you had to sometimes take it on the chin and just try to move on.

"When emotion gets the better of you, which happens to most people, a few words were said.

"In my career with him, I never saw him physically go at anyone, but words can hurt a lot. There were times he could have dealt with things in a different way."

He added: "There were always tough moments because every player had to be on their game.

"If training started at 9am, he would like you to be at training maybe an hour before, he'd like you to socialise with your teammates and have a bit of breakfast.

"The guys bought into the philosophy he brought in because you're only seeing each other for a short space of time during the day, but he wanted us to be more connected on and off the field.

"Everybody had to be on their A-game when it came to him, not just in games, but in training, in the way you carry yourself, because you're not just representing a Roy Keane player, you're representing the club.

"So he made those things very, very clear to the players."
