World heavyweight boxing champion Lennox Lewis says he will discuss his future with promoter Don King during a trip to Africa, insisting that at 36 his best is yet to come.

Lewis has been coy on his plans since crushing former champion Mike Tyson in a one-sided bout in Memphis, Tennessee in June to defend his WBC and IBF belts and cement his position among boxing's greats.

But arriving for a private trip to Ghana on Thursday night he put a damper on talk of retirement, saying he would be around to defend his title -- even though he dismissed the current crop of would-be challengers as no threat.

"The world has not seen the best of me yet," the fighter said.

"They are still babies to me out there. Maybe one great boxer will come up eventually. But I will be there for him."

Accompanied by his mother Violet and trainer Emmanuel Steward, Lewis is on a 10-day private visit to the West African country.

"Don King is also in town. Him and me will be talking about the future," Lewis added.

Lewis said he would also "teach some moves" to local boxers in Ghana, where boxing comes a close second to the greatest national sporting passion, soccer.

A previous trip to the continent of his forbears was less fortuitous for Lewis, who lost his title in a shock defeat to American Hasim Rahman in Sun City, South Africa last year. Lewis was better prepared for the rematch and recaptured the belts.
