Jamaican sprinter Usain Bolt has said that he wants to prove to the world and to American competitor Justin Gatlin that he is still the 'Sprint-king', following his 200meters victory over the latter.
Six-time Olympic champion insisted that he never had a doubt about this and added that his only worry was the fact he didn't race sharp, Sports24 reports.
Bolt, 29, has expressed his doubt about participating in the next World Championship in London in 2017, saying that he was fifty-fifty for the tournament, and added that he could take this decision only after participating in Rio.
Bolt clocked 19.55sec to win his 10th World Championship gold.
Controversial Gatlin finished second at 19.74 seconds, ahead of his South African fellow Anaso Jobodwana, who finished third in 19.87seconds.
Bolt and Gatlin will next meet again in the 400 meters relay on Saturday.
