James Dasaolu believes he can end a decade long wait for a British sprinter to win a world 100m medal.
Dasaolu announced his World Championship intentions with a storming 9.91 second performance in the semi-finals of the national championships in Birmingham last month.
But he hasn't competed since, pulling out of the recent Sainsbury's Anniversary Games at the Olympic Stadium.
He arrives in Moscow ranked fourth in the field - form which gives him hoping of matching Darren Campbell's bronze at the 2003 World Championships in Paris.
"I want to challenge the Americans, the Jamaicans and the best guys in the world and to do that I will have to run sub-10 on a regular basis, probably even go into the 9.8s," he said.
“Now I have gone sub-10, when I line up against other sub-10 guys, I know I have gone just as quick as them. It gives you confidence to run against a world-class field.”
Dasaolu credits new coach Steve Fudge - who believes his charge will run even faster in Moscow - with his new form.
In the past, he has struggled with injuries and he failed to progress beyond the semi-finals at last year's Olympics.
“I’ve been able to have a full winter and progress and build on what I did in 2012-13, hence why I am able to run a personal best,” added Dasaolu.
“I wouldn’t say I was a fragile athlete, I would probably just say I was doing the incorrect training, training that wasn’t really suited to me as a person.
“Training with Steve enables me to have a tailored programme. Now I’m in the right programme and healthy and fit and able to run.”
