Jamaican Usain Bolt has his sights set on smashing his already electrifying 100 metres world record, the triple Olympic champion said on Sunday.

"I think I could definitely go faster - 9.5," Bolt, whose record is 9.69 seconds, told Reuters in an interview.

"I think I could go 9.4, but I think the world stops at 9.4."

For 2009, Bolt, who broke the 100 and 200 metres world records and helped Jamaica to the 4x100 metres relay record at the Beijing Olympics last year, hopes to win similar titles at the world championships in Berlin in August.

But his ambitions do not stop there.

"I want to be a legend in sports," the 22-year-old told reporters earlier at a news conference.

"I want to just keep the level of competition high ... so when I face the media every year, they will say Usain was the only guy to, ever, every season be on top - that's my aim."

He brushed aside recent comments from British sprinter Dwain Chambers that he could be Bolt's key challenger in Berlin.

"As soon as you start focusing on one person, then you start losing," said Bolt, who plans to compete in Europe several times before the world championships.

"If I focus on beating Asafa (Powell), what about Tyson Gay?

"The only thing I have fear of is getting injured. I don't fear people."

The sprinter's traditionally fearless approach to his diet, however, has been curtailed by coach Glen Mills.

The pre-race chicken nuggets he downed in Beijing will take a back seat to more wholesome fare such as pasta and potatoes, Bolt said.

"I'm an only child of my mom," Bolt said with a sheepish grin. "If I don't have to worry about something, I don't."
