Sunderland midfielder Dickson Etuhu says Roy Keane is the ideal manager for him to work under.
"He wants to improve me as a player," said Etuhu.
"He has told me all the attributes I have and the ones I don't have. He is the perfect guy to teach me. Obviously, as they were playing in my position at that time, I would watch the gaffer and Vieira's battles. I wanted to be educated and get tips from the top players and they don't come much better than those two. The secret is to learn from him [Keane] in training, close him down and try to get the ball. It's not easy, he just lets the ball go at the perfect time, every time."
