Belgium's WBC lightweight champion Delfine Persoon has offered Katie Taylor much more than $100,000 for a unification showdown, according to her coach Filip Tampere.
Taylor's manager Brian Peters said the Bray boxer wouldn't get out of bed for $130,000 in reaction to reports that Persoon's team last week improved their $100,000 offer to $130,000 for a fight with Ireland's golden girl, who holds both the IBF and WBA lightweight belts.
"My offer to the Taylor team is a lot more than $100,000. If Delfine and Katie fight, it will depend (on) Taylor's team. Delfine is ready," said Tampere.
"Delfine don't fight for the money, she just wants to see who (is) the best."
Taylor's team have also been trying to entice WBO champion Rose Volante (14-0-0) out of Brazil for a St Patrick's weekend unifier in Philadelphia.
Peters understands that Volante's reluctance to trade leather is more fiscal than fistic but insisted they will not be held to ransom.
The unbeaten Sao Paulo puncher was given until midnight last Thursday to agree terms but that deadline passed without any deal.
Volante would almost certainly lose against Taylor, but Persoon has won 42 of her 43 fights and would be serious opposition.
Meanwhile, France's Rio 2016 Olympic champion Estelle Mossely, who beat Taylor in the semi-finals of the 2016 World Championships, is on course for a rematch.
The unbeaten 26-year-old stopped Poland's Sylwia Maksym in the third round in Deauville on Saturday night to record her third win as a professional.
"I have improvements to make with respect to accuracy. Next year I will fight 10 rounds," said the only woman besides Taylor to claim Olympic lightweight gold.
