Gatlin has Bolt and 2012 London Olympics in his sights

Gatlin was banned for four years in 2006 after testing positive for excessive testosterone. The former world and Olympic champion, who won his first competitive race since the ban in Estonia last Tuesday and clocked 10.17sec today, is aiming to reclaim his place among the elite.

Asked if he thought he would compete in the 2012 Games, the American sprinter told BBC 5 Live: "I hope so. I think I am a championship kind of runner and competitor and I have a big heart. I always rise to the occasion in competitions." Gatlin said he was unsure about his chances of beating Bolt. "I have to make sure I run good times before I can think about being in a race with him. I have been there before and raced against those guys before so I'm not going to be nervous or scared to run against them."
