Le Clos has archrival's records on his radar

Olympic champion Chad le Clos is aiming to break the 100m and 200m butterfly world records held by Michael Phelps at the Rio 2016 Games.

Le Clos told Rio2016.com on Wednesday that he has improved since the London 2012 Games, when he beat Phelps to win the 200m butterfly and finished second to the American in the 100m.

"The Rio Olympics is my main focus," the 23-year-old South African said.
