Lennox Lewis' trainer Emmanuel Steward has urged the heavyweight boxer to get back in the ring and defend his WBC crown one last time.
The 38-year-old Briton has not fought since June last year, when he stopped Vitali Klitschko, but Steward wants Lewis to bow out after a rematch.
"I would love to see him finish his career by knocking out Klitschko," Steward told BBC Radio Five Live.
"Lennox is too strong and too powerful a man for Klitschko to hold off."
The WBC has set Lewis a deadline of 15 March to decide if he will defend his title in a rematch with the Ukrainian.
The fight would be a massive money-spinner but Steward revealed he is in the dark about what Lewis' plans are.
"I don't know when he's going to make a decision on whether he's going to fight a rematch or retire," said Steward.
"I was told originally it was going to be at the end of January but now I heard that he may have moved it back to March.
"I'm hoping that Lennox will make a decision as soon as possible.
"Lennox has been a very busy champion up until the last year, so if he decides to take a break he deserves it.
"I don't want to see it because I want to keep him busy, but he has earned the luxury of making his own decision."
