Carr said: "George Graham was the best organised manager I played for and, technically, in terms of what he wanted you to learn, Glenn Hoddle was right up there.
"I think what our gaffer has got is drive. He has a hunger. I think you can see it in our players, too.
"I don't regret the break I had but I appreciate the game far more now."
Both Graham and Hoddle are currently out of work, despite their huge reputations.
