Dwain Chambers says he will smash the world 100m record this year.
Chambers will return to action this Friday
The European champion, whose current best is 9.87 seconds, believes he is ready to destroy Tim Montgomery's current record of 9.78secs - by over a tenth of a second.
"I get a lot of confidence from what Remi (Korchemny, his coach) says to me," said Chambers.
"He believes that the human body can possibly go to 9.65secs, providing you put the whole race together - and he believes I'm the one who can do that.
"I'm setting my goals on doing it this year. I believe 9.65secs will get me gold at the World Championships."
Chambers, 24, is bristling with confidence as he prepares for the World Indoor Championships next month.
I'd like to stake my claim by running consistently low 9.8secs
Having worked on his strength and technique while warm-weather training with Korchemny and Mike McFarlane in Miami this winter, he says he is in the best shape of his career.
"I've been working on a lot of weaknesses," revealed Chambers.
"I've gone back to scratch on my technique.
"I've also had some testing done on my feet, and I was diagnosed with a pronating problem.
"I'm having some spikes developed for me that will have me running in a more natural position and hopefully running quicker times.
"It would be nice to do it (break the record) at the World Championships, but I'd like to stake my claim by running consistently low 9.8secs and break into the 9.70s before then.
"That would put me one step ahead of the other guys psychologically at the championships.
"I will be scared as hell on that start line, thinking: 'This is mine, but I have to go and get it.' But the time is drawing near.
"Before last year, running 9.78secs didn't even come into my mind. But as I got closer to the 9.80s, I started getting more confidence.
"My 9.87secs in Paris came as a surprise - but I did not experience the full running of that time.
"I was dragged along. My mind was not focused on running fast times."
Chambers is no longer intimidated by the likes of Montgomery and Maurice Greene.
After winning his first major title at the Europeans last summer, he is ready to take on the world.
"Maurice is finding it tough at the moment, but I still believe he is a competitor - and he's the current world and Olympic champion, so I can't knock him for that," he says.
"I believe he will be back, but I'll be waiting for him."
Chambers makes his first appearance of 2003 on Friday in a star-studded 60m at the Norwich Union Grand Prix in Birmingham.
He will come up against British rivals Jason Gardener and Mark Lewis-Francis, both of whom are more suited to running indoors.
"I'm a little nervous about Friday because I haven't run indoors for two years," said Chambers.
"Those guys' forte is 60m. It's not easy getting out and beating someone over 60m because it's so short.
"They also run well to 60m outdoor. Outdoor I progress to another level, but now I'm coming into their domain.
"So, while I want to go out there and run as well as I can, my main focus is to work on my flat speed to help me outdoors this summer."
