Powell told the BBC World Service: “Going into Daegu I was the man to beat, I was the man with the fastest time in the world this year.
“To not be able to run, I was very very disappointed.
“It was difficult to take because I won the Jamaican trials quite comfortably, quite easily. To know the same guys I finished in front of went and got the gold medal, it made me look at things and think, ‘If I was there I might be world champion’.
“I always ask, ‘Why me? Why does this keep happening over and over?’… [But] I’m very strong. It gives me a lot more motivation for the 2012 Olympics in London – and a lot more rest.”
While injury-plagued Powell bemoaned his fate, Blake was lucky after the disqualification of dominant Bolt for false-starting was seen to have paved the way for his shock victory.
“Life has been good,” Blake said on Wednesday.
“I can hardly walk some places but it’s a wonderful feeling. I’ve been dreaming for this my whole life. I’m learning how to deal with it now.
