World champion Yohan Blake is determined to add the scalp of Asafa Powell to his Daegu gold medal when they race in the 100 metres at today's Diamond League event in Zurich.

I am back: Asafa Powell

Jamaican Powell is the fastest man in the world this year but had to miss out on the World Championships in South Korea because of a groin injury. However he is fit again and will take on compatriot Blake at the Weltklasse meeting, confident he can get the better of their battle.

Victory in Zurich would not make up for being forced to miss racing in Daegu, but Powell has a point to prove.
"I wanted to run at the World Championships," Powell said. "Even the final when I saw guys running the relay I was very sad but it happens. I just have to look forward.

"Blake is world champion and I can't promise a world record but I'll be out there competing. I'd love to win. I don't know what shape I'm in right now but I got a good feeling."

Blake said: "I finished the World Championships ranked number one and I want to keep it that way."
He added: "Definitely since the World Championships my life has changed. Like the press conference and getting calls. It's not going to be easy, but I think my agent and all the people around me are going to teach me to handle the pressure well.

"I've been running really good. The breeze has been giving me good times, at -1 to -1.5. But I'm not really looking for a time. I like to let my feet do the talking and the time will come if I execute a perfect race."
