Usain Bolt says he plans to retire after the 2016 Rio de Janeiro Olympics.

But the sprinter told a news conference he wants to win another gold before retiring for good.

He revealed: "If I want to be among the greats of (Muhammad) Ali and Pele and all these guys I have to continue dominating until I retire.

"If I'm in great shape and I go there and do what I have to do, I think it would be a good time to retire on top and having dominated for so long."
