Shields, 29, is undefeated in 14 pro fights and was the first fighter, male or female, to be undisputed champion in two weight classes in the four-belt era.

The two-time Olympic champion has been world champion at middleweight, light-middleweight and super-middleweight.

Irishwoman Taylor replicated Shields’ undisputed achievement last year, while Puerto Rico’s Amanda Serrano is a seven-weight world champion.

“Everyone is talking about who’s the GWOAT? Who’s undefeated? Who got the most belts?,” Shields added.

“Who made the million dollars last couple of time she fought? Without a promoter giving her a handout? That’s what a GWOAT is. Who fights the best?

“Who don’t struggle in fights no matter what size? Exactly.

“All that comparison about who the GWOAT is, I can go to any weight class and win. That’s who the GWOAT is.”

The WBC title Shields challenges for is classified as ‘heavyweight’ by the sanctioning body, but it is contested at the light-heavyweight limit of 12st 7lb (175lb), hence why the fight is being advertised as both at heavyweight and light-heavyweight.
