Derby County goalkeeper Roy Carroll is delighted for his former Manchester United teammate Roy Keane and his managerial success with Sunderland.

Carroll said: "I have good memories of Roy.

"He was a top captain at United and I spoke to him a lot about football.

"It is great to see him doing so well in his first manager's job. I could see he would make a good manager.

"As a player, he gave 100 per cent on the pitch and on the training ground as well.

"That is the way he is and I'm sure he is the same as a manager.

"He does look calm on the sidelines but I suppose he has to act like that because Sunderland have a young side and you can't keep shouting at young players."
