SPRINTER Adam Gemili insists he would have no problem spoiling Usain Bolt's farewell party at the World Championships.

The 23-year-old is out to make up for last year's Olympic disappointment by shining in London in August.

Bolt is planning to retire after the championships following his eight Olympic titles and two world records in the 100 and 200 metres.

And, ahead of the London showpiece, Britain's Gemili is aiming to line up against the Jamaican in the 200m and wants to beat him.

"He's done so much for the sport, he's taken athletics to another level and it's going to be a real shame when he does retire," said the 2014 European 200m champion.

"I feel very fortunate I get to compete in that sort of era but on race day I'm going to give it my best to try to beat him. You want to beat everyone and if you don't want a gold medal I don't understand. If you don't want to be the best it's not the sport for you.

"Right now Bolt's the best ever, I don't think anyone has done what he's done in terms of the world records and Olympic titles.

"In terms of sprinting, anyone who tries to say otherwise would have a hard case to argue against."

Gemili finished fourth in the 200m as Bolt took gold at the Rio Olympics, missing the podium by just three thousandths of a second, and the Londoner believes the disappointment has given him extra motivation this year.

He said: "It took a while to get over. To get so close to something and not achieve what you wanted to achieve...it was the culmination of four years' hard work and was tough to take.

"I'm working extra hard this year and making sure I don't feel that thing again. I'm making sure when it comes to London I have no regrets, I have extra fire in my belly."

The World Championships start on August 5 with a cloud continuing to hang over athletics following European Athletics' proposals to overhaul the world record lists and eliminate any doping doubts surrounding performances.

All pre-2005 records could be rewritten under the new rules, which need to be ratified by governing body, the IAAF, but Gemili conceded athletes cannot control what happens.

He added: "It's a bit crazy, in terms of an athlete's perspective I'm sure most don't just want to be handed a world record, they want to earn it. It'll be a real shame if the clean guys have to miss out but it's out of our hands."
