Sun hoping to shine in Rio

Double Olympic champion (400m and 1500m freestyle), 7-time world champion (400m, 800m and 1500m freestyle), and world record holder to boot (1500m), Sun Yang will be one of the men to beat in Rio.

In spite of making the headlines for the wrong reasons in 2015 (doping allegations, injuries, clash with a Brazilian female swimmer, shock absence from the world 1500m final in Kazan), the Chinese remains one of the top favourites for the long-distance events in Rio.

At 24, Sun is preparing for already his 3rd Olympics, and will be hoping to add to his 4 medals from London 2012 (2 gold, 1 silver, 1 bronze). Having dreamt of being a pop star in his youth, he'll look to give the Chinese fans something to sing about in Brazil.
