Chambers, was second in 10.15sec, into a headwind of 0.1 metres-per-second.

Australian Matt Shirvington was third in 10.25sec.

Lewis-Francis shrugged off the idea of being motivated by a possible share of US$1m prize money for winning at all of the six Golden League meetings.

The 20-year-old said: "I'm running for championship medals - that's my aim. The money is just a bonus.

"What I want is to be the best in the world. I'm so young and I want to run and win medals for my country."

You have to take the rough with the smooth Dwain Chambers

Chambers refused to blame an incident in training on Thursday when a blow to the head from a football left him unconscious.

"You have to take the rough with the smooth," he said.

"It just ain't happening, although I'm getting better in my running. A and B are not adding up logically and making C."

Berhane Adere of Ethiopia missed the women's 5,000m world record by only 1.23 seconds, setting the second fastest time in history of 14:29.32.

China's Jiang Bo set the world record of 14:28.09 in 1997.

"It was a fantastic race," said Adere, who led an Ethiopian sweep of the first four placings.

"I thought it was possible to break the world record. But there was only one pacemaker and that's probably why I didn't make it. Hopefully I'll break it next time."

Werknesh Kidane finished second in 14:33.04 for a personal best. Third-placed Tirunesh Diababa, who is 17, broke the world junior record with a time of 14:39.94.

The meeting at Bislett is the final one at the old stadium, which is being torn down and replaced with a new facility this summer.

New personal best

Former European champion Iwan Thomas finished third in his 400m race won by Belgium's Cedric Branteghem in a personal best 45.55secs.

Thomas led early but faded coming off the final bend.

Australia's Clinton Hill also passed him to cross the line 0.02 ahead of the Welshman in a time of 46.09.

London-based Cuban Yamile Aldama jumped a massive 15.11-metre triple jump to smash her personal best.

Aldama, the 1999 world silver medallist is unbeaten this year in her four competitions but could miss the World Championships.

Commonwealth silver medallist Francoise Mbango claimed second place with a season's best of 14.88m while world champion Russia's Tatyana Lebedeva was third with 14.86m.

In the 400m hurdles Tony Borsumato ran a season's best of 50.87 seconds, but finished second behind Russian Boris Gorban.
