Jamaican Usain Bolt [ Images ], who shattered the 200 metres world record to win gold at the world championships on Thursday, said he is closing in on his biggest aim of becoming a sprinter the world would not forget.

"I keep telling you guys my aim is to become a legend. I don't think about records. I don't put myself under pressure. I know what to do and I go and execute," the 22-year-old told reporters.

"I did well for myself and I am on my way to becoming a legend so I am just happy."

Bolt claimed three gold medals at the Beijing [ Images ] Olympics [ Images ] last year and two at these world championships in Berlin, smashing the world records on his way to every title.

In the same stadium where American Jesse Owens [ Images ] won four gold medals, including three in the sprints, at the 1936 Berlin Olympics, Bolt knocked off 11 hundredths of a second in each of his two gold medal races, the 100 and 200 metres.

"I keep saying anything is possible. You work hard, you train hard. I still train very hard and running fast races doesn't change that," he said.

Bolt said he is not interested in convincing those who did not believe the records are a result of his hard work, saying that questions about doping are an inevitable part of athletics.

"I am not worried. I don't get offended," he said. "I know it is going to be always like this in the sport."

Asked whether a knighthood from Queen Elizabeth would be something he would like, Bolt said: "I just say that would be a great thing. Seriously that would be wonderful."

"I would get the title 'Sir Usain Bolt'. That sounds very nice."
