Bolt is not invincible, says Powell

amaican sprint king Usain Bolt is no "superman" and can be beaten, his compatriot and rival Asafa Powell insisted on Tuesday.

"Well anybody can be beaten but in the 100 metres right now Usain is running very fast... So you really have to be at your best on that day to win the race," said Powell, ousted by Bolt as the world's fastest man last year.

"It's pretty much the best man wins on that day and there's no real superman or anybody that is invincible," he said in a forum with Singaporean students, part of promotions for the 2010 Youth Olympic Games in this city-state.

"So anybody can be beaten."

The 27-year-old Powell later told journalists that "Usain is the target right now and I'm shooting at him, hopefully I don't miss".

"I still have confidence in myself, I know I can do it," he said.

Bolt (23) smashed his own 100m world record with a time of 9.58 seconds at the Berlin world championships in August.

American Tyson Gay claimed silver in 9.71sec, finishing a good couple of metres off Bolt, with Powell clocking 9.84sec for bronze.
