While they both insist it isn't personal between them, the build-up between Natasha Jonas and Lauren Price has been tetchy to say the least.
With three belts up for grabs -- Jonas' WBC and IFB titles, as well as Price's WBA welterweight strap -- the tangible prizes are obvious. But dig a little deeper beneath the surface and it becomes clear why this fight means so much more than just the titles.
Price (8-0, 2 KOs) and Jonas (16-2-1, 9 KOs) will headline an all-female card on the eve of International Women's Day at London's iconic Royal Albert Hall on Friday (Sky Sports, 6 p.m. GMT)
The winner will join the likes of Henry Cooper, Naseem Hamed, Frank Bruno and Lennox Lewis to have their hand raised at the venue. More to the point, they will be one step closer to an undisputed fight against Mikaela Mayer or Sandy Ryan, who fight for a second time on March 29.
The verbal back and forth has been tense. Price doesn't believe Jonas wants to fight her, while Jonas doesn't think it will be her toughest test. Price is unbeaten as a pro but Jonas has been quick to point out her inexperience, and the fact she hasn't been in the trenches of a huge fight.
The fight has also been teased as a potential "changing of the guard." Jonas, 40, considered retirement last year. But if "Miss GB" can stop the up-and-coming younger opponent she could go on to fight for all the belts in a bout that would take her legacy to the next level.
But Price, 30, is more than confident in her ability. "Too young, too quick, too good" has been her catch cry.
"I just think there are a lot of experiences I've been through. But as for them rounds in the ring, there's some things [Price] hasn't been through and experienced as a pro," Jonas told ESPN.
"Do you think you're faster than Katie Taylor, or Caroline Dubois? They're the types of speed that I'm used to. She is fast, but she's fast for a 75 [kilogram] boxer against another. I know what fast is. I've been with someone who has the fastest hands in the game."
A Commonwealth and Olympic gold medallist, Price has also said she could have fought for a world title in her first pro bout, something Jonas scoffs at.
"When she says [I'm] not as good as [Mikaela Mayer] ... I just think she's probably saying it just for the cameras or to try and get under my skin, but she knows how good I am. It's nothing personal. It's a great fight and I respect her, but I just believe I'm better in all areas," Price told ESPN.
"I've been to every single amateur tournament and I'm the most decorated amateur to come out of GB. I've faced southpaws, orthodox, people on the front foot, back foot, heavier girls.
"Yeah, she's got more experience in the pro ring, but when I look at the calibre of who she's boxed apart from Katie Taylor, apart from Mayer and the girl who knocked her out [Viviane Obenauf] ... I don't rate anyone else she's fought."
Despite her superior experience and the fact she holds two belts, Jonas is claiming the underdog tag.
Jonas' trainer Joe Gallagher took aim at those who have "bought in" to the hype around Price and dismissed his fighter.
"She has been dropped as an amateur, she has been dropped in sparring, she's not this unbreakable [force] that everyone is trying to create a narrative for," Gallagher said at Tuesday's media work out.
"This isn't me out of emotion ... I just think there's so many 'worldly minds,' boxing people that are getting bought into this.
"Tasha's been beat, but we're not making out we're unbelievable, [that] we haven't lost a second of a round.
"Lauren will lose a round on Friday night and she'll lose the fight. Mark my words, that will happen and I want to see everyone come out then and give [Jonas] her flowers and apologise for overlooking her for this fight."
