Unified middleweight and junior middleweight champion Claressa Shields is willing to fight amateur rival Savannah Marshall - but she wants to be properly paid for the contest.
Shields, a two-time Olympic gold medal winner, lost a decision in the amateurs to Marshall, who is now the WBO middleweight champion.
Shields' adviser, Mark Taffet, likes the idea of matching his boxer against Marshall - as long as the two fighters are properly compensated.
He wants Marshall's promoter, Eddie Hearn, to present a favorable offer for the fight.
"We love the Savannah Marshall fight," Taffet told Sky Sports.
"But we want [Marshall's promoter] Eddie Hearn, other promoters and the networks to join us in making significant advancements toward equality for women.
"And that includes appropriate pay for premium events. We are at a crossroads in the history of this sport, a transformational moment where the greatest female fighter in the world stood tall to make a point. Claressa Shields competes against women but she fights for equality. The time is now."
Shields was in action last week, when she dominated Marie-Eve Decaire to unify the WBO, IBF, WBC, WBA world titles at 154-pounds.
In several interviews, she expressed her interest in facing Marshall.
"It is so sad for her that she wanted to wait for my belt to become vacant, rather than fight me for it," Shields previously told Sky Sports about Marshall.
"That's so soft. She could have fought for all the belts at 160-pounds to show how tough she really is. Savannah's coach Peter Fury said she's too strong for me? Shut up, shut up! Savannah hasn't been challenged enough yet for her to even be saying my name.
"But if she wants to come see me? Then come see me. I'll shut her and her team up because they do too much talking for me!"
