Jamaican sprint star Usain Bolt has laughed off suggestions by disgraced Canadian sprinter Ben Johnson that he could have beaten him.
Johnson was stripped of his 100 metres title from the 88 Seoul Olympics after testing positive for anabolic steroids.
Last week Johnson suggested the sport still has major problems and that he had a role to play to prevent athletes making the same mistakes he did.
Johnson also said that at his best he could have beaten the current world record holder Bolt.
Bolt has dismissed the suggestions.
Johnson ran 9.79 seconds in Seoul, while Bolt's current world record is 9.58 seconds.
