Oleksandr Usyk is already a generational great, if not an all-time great.
An undisputed champion at two weights, and the first heavyweight undisputed king in the four belt era, and first in 24 years. His class, pedigree and legacy is not in question.
A second victory over Tyson Fury on Saturday night, live on DAZN PPV, just cements everything we already know, respect and revere of the Ukrainian, while strengthening the argument to put him at the same level as Joe Louis, George Foreman, Lennox Lewis and Muhammad Ali.
So, if 'The Cat' sees off Fury again, what does the 37-year-old have left to achieve? What other worlds does he have to conquer?
Many have suggested it would be the perfect time for Usyk to retire. He, himself, has hinted this week he would fight on, potentially returning to cruiserweight, but could that just be a pre-fight deflection?
DAZN News's boxing experts deliver their verdict on whether Usyk should retire, if he wins again.

A second win over Tyson Fury would be the perfect way for Oleksandr Usyk to close the curtain on his career.
An undisputed champion in two weight classes is a boxing CV those who put on the gloves for the first time can only dream of.

It would be the perfect time, wouldn’t it?
Boxing connoisseurs would probably want him to carry on as he is such a joy to watch - a real ring mechanic - but should he prevail again against Fury do we really want to see him in again with Daniel Dubois or have a third fight with Joshua?
Also, at the venerable age of 37 does he have the motivation to grind out more long training camps to face younger lions like Martin Bakole, who surely deserves his crack at some point in 2025?
Usyk is a man of few words but the way he has been speaking ahead of this seismic return fight indicates the end may be near.

With victory, Usyk will have firmly shut the door on all his heavyweight rivals.
By far the best heavyweight of his generation with another win, there will be nothing left for him to accomplish unless he wants to go over old ground.
Could a Daniel Dubois rematch or Joseph Parker fight tempt him depending on their February result?
Becoming undisputed for a second time may appeal to Usyk but his biggest battle if he does decide to stay on could be against the governing bodies, who will be quick to get him back in action.
Usyk has nothing left to prove to anybody and he should walk away with his health and ledger perfectly intact and enjoy the fruits of his labour.
Mark Lelinwalla - boxing analyst
If Usyk wins, perhaps he can complete the undisputed crown once again.
Or if he wants to leave fresh off of serving two losses each to Joshua and Fury, Usyk could exit on top of the game.
I think, depending on the severity of the fight, if Usyk wins, we might see him leave the game as the best on top.
