Usain Bolt has claimed that he has "no respect" for Carl Lewis following his win in the 200m final at the London Olympics.
Lewis has previously raised questions over the potential use of banned substances by Jamaican athletes in track and field.
When asked his opinion of nine-time gold medal winner Lewis, Bolt told reporters: "I have no respect for him. No respect."
Bolt became the first man in Olympic history to successfully defend both his 100m and 200m crowns when he triumphed on Thursday.
