I've just read this anecdote in The Times about Charlton and thought I would share it.
"He had gifts to die for," Alan Ball, Charlton's England team-mate, once noted. He told of Sir Alf Ramsey one day asking if he had a dog, and how the dog would fetch a ball and bring it back to its owner. "That's what I want you to do for Bobby Charlton," Ramsey told Ball.
