TOKYO - Japan's figure skating king Yuzuru Hanyu on Wednesday warned rivals that his Olympic and world gold medal double was no fluke, promising more fireworks. The 19-year-old, who also won the Grand Prix Final before repeating his Sochi heroics on home ice at the world championships in March said: "As Olympic champion I want people to realise that my gold medals were no coincidence -- I won them because of my ability." Hanyu won Japan's only gold medal of the Sochi Olympics in February as he broke his own world record in the short programme en route to becoming the first man from his country to win Olympic gold in the sport. Achieving so much at such a tender age, including becoming the youngest Olympic men's champion in 66 years, has clearly not diminished his hunger for more success.–AFP
