Lord Sebastian Coe is not only the head of London 2012, he is an Olympic gold-winning middle distance runner - which means when it comes to picking a favourite for the 100m, his opinion counts.

Whilst many former athletes have their eyes on Yohan Blake to win, Coe reckons it is going to be Usain Bolt taking gold.

"I still instinctively think that Bolt will win this, simply because he has that crucial asset which is precious in a major championship and that is experience of major championships. I just sense he might know how to close this out, but Blake is a phenomenal talent," he told reporters.

He added that there could even be a Jamaican clean-sweep of Bolt, Blake and Asafa Powell, saying: "We are possibly looking at Jamaica one, two, three here."

Bolt is still the bookmakers favourite, but fellow Jamaican Blake is moving up in the odds.
