With the lightweight division well and truly unified, Katie Taylor has nothing left to prove since becoming the undisputed champion.
Seventeen fights unbeaten since turning to the professional ranks, the Bray native has come up against every style of fight and fighter, from the wily old pro to the street-fighting brawler, and apart from the very odd wobble, she has come through relatively unscathed.
So what harm in a spot of reminiscing this week with the highly anticipated match-up against old amateur foe Natasha Jonas, which takes place on the undercard of Dereck Chisora's heavyweight clash against Joseph Parker at the Manchester Arena tonight.
Taylor fought Jonas at the London Olympics and while the bout came early in the competition, it proved a groundbreaking encounter for the women’s sport as a packed venue watched the golden girl of amateur boxing take on and comprehensively beat the Team GB local hero.
Four-times a world champion ahead of the Games, Taylor’s prowess in the sport was one of the main factors in bringing women’s boxing into the Olympics, and she did not disappoint at the London venue, both in the Jonas bout and on to securing gold.
"The Irish fans brought up the decibels in the arena that day and it was a great week for me to achieve a childhood dream," said Taylor, enjoying a brief trip down memory lane earlier this week.
"It was the first time that people saw women’s boxing on the global stage, and many people feel that the fight between me and Tasha was the fight of the tournament, the atmosphere was electric and we showed everything in that fight, the skill the heart."
Chalk and cheese, you might describe the four-round amateur fight back in 2012 compared to the ten-round championship encounter that will take place tonight at around 9pm, with all Taylor’s world titles on the line.
But the nostalgia has brought a real interest in tonight’s fight, as Jonas remains a well-known face in the boxing world thanks to her television work as well as proving herself at the top level in a world title fight with Terri Harper last August, which ended in a draw.
And while the Wicklow woman has come into the fight with that quiet confidence of a true champion, Jonas has been attempting to talk up her own chances, saying that she has unfinished business coming into the fight.
Jonas’ coach Joe Gallagher has also been trying to hype things up this week, stating that Taylor is vulnerable and can be hurt, however, it really had no effect on the undisputed champion who smiled and said she would do her talking in the ring.
Unfinished business might suggest that the English woman was hard done by in the Olympic bout nine years ago, but while she gave a good account of herself, most notably in the second round, she was outclassed by the Irish fighter.
The Liverpool boxer even admitted that Taylor was the one fighter she did not want to meet in the draw, stating "I honestly believe the only person who could have beaten me in those Olympics was Katie".
So it beggars belief to think that she has improved over the intervening nine years to the point that she is now capable of beating her former nemesis.
If anything, Taylor has widened the gap between the two fighters, as the lightweight champion has become teak tough since turning pro, having come through real wars in the ring, most notably in that first fight with Delphine Persoon.
Many fighters would have taken the decision and run to the next challenge, but Taylor silenced the doubters by proving herself a better boxer in the re-match, cementing her legacy as the best in the business.
Jonas’ rise through the paid ranks came a cropper in fight number seven as she was knocked out by Viviane Obenauf back in 2018, a fighter that Taylor cruised past in a six-rounder in what was only her second fight as a professional.
Looking ahead to the fight, Taylor will not fear but relish stepping into the ring with someone who came through the ranks the same way, learning their trade in the amateur game, and as a result, she will not have to fear the unexpected that has come in some of her professional dust-ups to date.
Jonas, of course, boxes with a southpaw stance, but again, it should not worry Taylor whose footwork and hand speed are exceptional.
Taylor has, at times, allowed herself to get involved in a brawl, and while Jonas will look to stay close, tuck up and unleash close-range power shots, the champion will be able to steer clear of danger and fight off the back foot.
But there is the entertainment angle, and it would be no surprise to see Taylor stand toe-to-toe with Jonas and prove once again that she is not just a better boxer but also a more accomplished, stronger and more powerful fighter.
Jonas cannot seriously believe that she can take the contest on points against an esteemed opponent of Taylor’s class, and she will be coming to look for the stoppage.
So perhaps for those opening two or three rounds, Taylor needs to maintain a disciplined approach to ensure that she does not allow an over-eager Jonas land a big shot that could cause the unlikeliest of upsets.
And once those opening stanzas are negotiated, the class of Katie Taylor will shine through and if Jonas makes it to the final bell, it will be just about the best she can hope for.
