Goalkeepers Are Different by Brian Glanville (Crown Publishers 1972)

Now and again he played in the games himself, like Charlie Macintosh, and you couldn't have had two more different players. His control was lovely, Billy's, he could do anything with a soccer ball, juggle it from foot to foot until you got tired of watching him, flick it over his shoulder with his heel, pull it back with the sole of his boot then go on again, in the same movement; he was lovely to watch. "Two stone more," the Boss used to say, "two inches more, and Billy would have been the greatest." One day Billy looked at him, deadpan, and said, "No, I wouldn't. I'd have been a player like you."
