With the Olympic Games very much in our thoughts here in the UK, I thought it time to have a look at the biggest star due to fly to London to compete, the phenomenal sprinter and current 100m champion Usain Bolt. It is interesting that recently he has not been his normal unbeatable self, and lost to his compatriot Yohan Blake twice recently. Looking at his stars, one can see why he has not been on form and he arrives in London under a cloud of uncertainty.
