As representatives of England, the newly married young royal couple, William and Catherine, may officially favor Murray.
But I saw Prince William come to see Roger play at the Australian Open a couple of years ago, and my, he mouthed "unbelievable!" In a one-on-one sport, it's nice to have your own nationality as a champion, but actually, the greatest talent, the greatest player brings the greatest honour to the game. And that is Roger Federer. ( And at the Olympics, for all other games, I favour my nationality, if there is a credible contender.)
