Olympic gold medallist Usain Bolt has admitted that he is beatable ahead of tonight's 200m Diamond League meeting in Paris.
BBC Sport quotes him as saying: "When I'm in great shape and I'm at the top of my game, I'm very confident that no-one can beat me because I know what I'm capable of.
"But you can be beaten. There's times when you get injuries, there's times when you're off your game. There's so many different scenarios that can happen."
US sprinter Gay holds the 2013 record over 200m with his time of 19.74s, with Bolt in second on 19.79s.
