Chad le Clos has revealed his excitement at winning gold in the 200m butterfly ahead of his "hero" Michael Phelps.
The South African edged out the 14-time Olympic gold medalist to record the victory by a fraction of a second and has admitted that he just wanted to make the final.
Le Clos told BBC Sport: "That's been my dream, ever since I was a little boy. Michael is my hero.
"I just wanted to race in the final and now I've won it. I can't believe it, I really can't."
Le Clos adds his Olympic gold to the Commonwealth title he received in Delhi two years ago.
