John McEnroe

For some sportsmen there is no such thing as retirement, not really. Their game has usually chosen them, rather than the other way round, and they never lose respect for that fact…. McEnroe's forthcoming autobiography is not called Serious for nothing. Out on court at the Albert Hall he is giving a full house a perfect impression of the man and the player he always was: creating every angle, arguing every call, staring at every line, making every volley, torturing himself over every missed ball.
