The small seaside English town of Brighton was awash with emotion on Saturday when Japan pulled off one of the biggest upsets in the history of sports, downing two-time World Cup champions South Africa 34-32 four minutes after the final siren. Written off before the game at almost impossible odds, coaches, fans and players alike could not hold back the emotion, balling their eyes out and hugging strangers while dancing for joy. In the cynical world of modern professional sport this was a great reminder why we love it so much, because it is the moments like these that make it special.
