If Andy Murray beats Federer in the Tennis US Open, he'll be the first British player to win a Grand Slam Final since 1936.
Right now, he's 2 sets down, and in the increasingly likely event that he loses, the English media will describe him as 'Scottish'.
If he wins, he will of course be "British Tennis Star Andy Murray".
On the plus side, win or lose, Federer is still a dirty Swiss.
