No player ever was at his best at 40. In Pancho's time the prime of the top players was from about 25-30, more recently from 22 to 29.
Rosewall was greater ( and that is a lot) at 40 than Pancho himself.Tilden,Connors,Kramer,Bromwich,Sedgman,Ash e,Agassi,Gimeno and Laver are the other guys that, for a while could play as well as in their peak once they got over 35 or 36.
