Dwain Chambers has welcomed the International Olympic Committee’s (IOC) decision to re-test samples provided for doping tests at the Beijing Games.

The IOC and the World Anti-Doping Agency will work together to determine how many of the 4,770 samples given during the Olympic Games should be re-examined. The review has been ordered after traces of banned blood-boosting substance EPO Cera were found during a recent re-test of samples from the Tour de France.

"It's going to be very interesting and also very disappointing because all of those performances we thought were clean are now going to be exposed," he said. " It shows the testing procedure is getting more stringent and it puts out a strong message, and that is something I am supporting.

"I'm curious to see the outcome of and hopefully we can start working towards a clean sport for 2012. I'll keep my fingers crossed and hope, for a start, that none of our Brits come back positive."

As for the Beijing Games recently, Chambers - banned from the Olympics after his two-year suspension for taking the performance-enhancing drug THG in 2003 - said: "I was disappointed none of the Brits made the 100m final and we didn't perform as expected in the relay.

"I could have been there, I would have loved to have been there. My actions prevented me from being there. It is tough to deal with. I'm getting over it now, channelling that energy into next year."

Chambers also revealed he was looking forward to facing Usain Bolt next year

He said: "I had the privilege of training with him in 2006 and I always knew he was going to run fast. But I never expected him to run as fast as he did. It was thrilling to watch and he's lifted the bar to a new level.

"I'm thoroughly looking forward to competing with him next year."
