Usain Bolt insists that he is not yet a legend despite his achievement at the London Olympics.

The Jamaican sprinter won the gold medal in men's 100m final on Sunday, his second of his career following his triumph at the Beijing Olympics four years ago.

Bolt clocked an Olympic record time of 9.63 seconds, and although he is proud to prove his doubters wrong, he stresses that he has more to win.

"This gold means I am one step closer to being a legend so I'm working toward that," said the 25-year-old. "That's just one step, I have the 200m to go so I can't celebrate.

"The reason it's sweeter is because a lot of guys doubted me so I had to show the world I am the greatest.

"It means a lot because there were a lot of people doubting me, it was great to come out and show I am still number one, I am still the best."

Bolt will now aim to win the men's 200m race later this week.
