Kirani James: "I can't believe it"

Kirani James has admitted that he was shocked by his Olympic gold medal performance during the men's 400m final this evening.

The 19-year-old powered down the home straight to leave his rivals trailing in his wake, clocking his first ever sub 44-second time in the process.

Having also become the first athlete from Granada to win a gold medal at the Games, the youngster expects that his home nation will be "going crazy" in celebration.

"The whole of [Grenada] is probably going crazy right now, I can't believe it," he told BBC Sport.

James also won the World Championship in Daegu last year.
