Jamaican runner Usain Bolt
"I look at this as an opportunity to make up for the world championship, I am looking forward to this," the lanky Jamaican, who holds the 100 metres world record, told a news conference in the Croatian capital on Monday.
The Zagreb grand prix will be Bolt's first 100 metres race since his controversial disqualification for a false start in the final in Daegu, South Korea last month.
"I am coming here to do my best, to try to run fast. I missed out on the world championship, so I want to see how fast I could have gone. I am still feeling good. I am pretty confident and am just looking forward to it," Bolt said.
"I am focused, determined to be the best at what I do, so I am just looking forward to the rest of my season and the rest of my career".
The 100 metres is scheduled for 1800 GMT on Tuesday.
