37-year-old Gatlin, who has two doping convictions behind him, reached out to Coleman's defense when he was suspected of doping crimes after failures in stay reporting. Coleman was released as late as three weeks.

- Justin Gatlin is a decent guy and a great athlete. He's always been there. I remember seeing him as early as 2004 (Olympic gold at 100 meters) when I was eight years old and thinking about it so many years later when I won gold is a fantastic feeling, says Coleman according to AP.

Justin Gatlin evokes strong emotions and was booed when he won the World Cup gold in London two years ago. Gatlin has had injury concerns throughout the season and did not convince in either trials or semifinals before he clinched the silver.

Gatlin promises to be better at the Olympics next year

- This season has been a testament to my endurance and will. I've had hardships. I just wanted to focus on this race and gave everything and got what I had in me this season, says Gatlin according to the BBC.

Gatlin is a mentor and training buddy with the 14-year-old Coleman who has now definitely taken over the throne at 100 meters.

- Christian has had a fantastic season with fast times. I can't say I'm shocked that he did a good job here, says Gatlin, who promises to bet against the Tokyo Olympics in ten months.

- I will, I will get better and I will be ready, Gatlin promises.
