Usain Bolt has reiterated his intention to retire after next year's World Championships in London following claims the sprinter could compete at the Tokyo Olympics 2020.
The holder of nine Olympic Gold medals made his retirement plans very clear even before this year's triumph at Rio and cited 2017's prestigious event as the final time he will be spotted on the track.
Michael Phelps reversed his decision to retire after London 2012 to return for this year's Olympics in Brazil but Bolt has explained why he will not be tempted into making a similar return.
"That will not happen," the 30-year-old told Sport Bild, as per Yahoo Sport.
"I won't know how to motivate myself by then. I don't have to prove anything to anyone.

"His (Phelps) swimming can't be compared with my running. Swimming is something natural. Michael will continue to swim after his retirement.
"But 100 and 200 meters of running, this is nothing natural. If you stop this, you don't start again. At least I will not."
Olympic fans around the world will breathe a sigh of disappointment following Bolt's latest update.
The 2008, 2012, 2016 Olympic champion has become one of the greatest athletes of all time and provided some of the best sporting highlights of our generation.
But Bolt was quick to praise German doctor Hans-Wilhelm Muller-Wohlfahrt for his work behind the scenes to get the Jamaican into the right shape to defend his Olympic crowns and etch his name even further into the history books.
He added: "Without Mull, I could not have won my three gold medals in Rio.
"He is almost a family member. I trust him 100 percent."
So it wasn't quite the news we were all hoping for, but it does mean next year's World Championships will have even greater significance.
