Sun looking to scorch Aussie in reprise of Rio showdown

China's Sun Yang, the enfant terrible of competitive swimming, is set to undergo another test of his fragile temperament at the world championships after a turbulent 2016 Rio Olympics.

Likewise, there will be nowhere for Joseph Schooling to hide in Budapest this month after he stunned Michael Phelps to win Singapore's first-ever Olympic gold last year.

Once called a bad boy, Sun spearheads China's assault and will be looking to exact revenge after Australian Mack Horton robbed the hulking Chinese star of his Olympic 400 meters freestyle in Brazil.
