Dwain Chambers insists he has the bottle to land a major global title despite his failure to win the World Championships 100 metres crown in Paris when favourite for gold.

The 25-year-old is so gutted after finishing fourth in Monday's final that he has not yet been able to watch the video of the equal slowest, but closest, final in championship history.

But Chambers vowed to bounce back and strike Olympic gold in Athens next summer, although it will take him longer than last year when he recovered from his Commonwealth disappointment to take the European title just days later.

"I don't buckle under the pressure," said Chambers, who clocked the same time of 10.08secs as silver medallist Darrel Brown and bronze medal winning team-mate Darren Campbell, with Commonwealth champion Kim Collins of St Kitts & Nevis winning in 10.07.

"I was here for the gold, to be number one in the world, and I didn't get it. But I cannot be any lower than I was after the Commonwealths last year and the things that were said about me then.

"From that I got a quick chance to put it right but now I have to wait a year for another opportunity.

"I just don't know how this can happen to me again. I keep taking these shots, but if I have to win the Olympic gold the hard way, then so be it."

Chambers, who will spearhead Britain's sprint relay squad that have a chance of gold with the Americans vulnerable, threw away his spikes as he hurried from the Stade de France after missing what could be his best ever chance of a global title.

"It was whoosh, I was out of there. I did not want to see or talk to anyone," he added. "I went through the race in my mind and I cannot tell you what it was like knowing the gold medal was there for me to win and I did not do it.

"I did not want silver or bronze. I was not bothered about getting either of those medals. I will look at the vide but not yet - it is too raw."
