Mexico City, Oct 9 (IANS): Jamaican Usain Bolt, the fastest man on Earth, seeks to win once again at Rio de Janeiro 2016 Olympic Games and become "a legend", he said.

Bolt, the world and Olympic multi-champion, said this at a press conference on Wednesday night during his visit to Mexico City for a commercial campaign, Xinhua news agency reported.

"Defending my Olympic title motivates me. I do not know what will happen with me if I lose a competition. I focus a lot, I get excited and the results depend on my hard work and my will to win," he said.

"If I go to Rio and win, I will feel very good and become a legend. And if people ask me, I will say that I am a legend," Bolt added.

He also said next week he will begin training for Rio 2016.

Bolt said he is taking a rest after winning at the 2015 World Championships in Beijing, where he arrived after recovering from an injury.

"It was definitely one of my biggest challenges because it was a short and tough season and I had to work hard. I was very focused, I ran well and achieve it," he said.

The Jamaican star also talked about soccer. He said he is fan of England's Manchester United and of Portuguese star Cristiano Ronaldo, player of Spain's Real Madrid.
