Caroline Dubois has been compared to Claressa Shields by former cruiserweight champion Johnny Nelson.
Dubois fights this Saturday to face Magali Rodriguez for the vacant IBO lightweight championship.
Nelson believes that Dubois can match the star power of PFL star and undisputed light middleweight boxing champion Shields.
"From turning professional, Caroline has captured everyone's attention from the seasoned pros, from fighters like Claressa Shields who could end up being Caroline's foe," he told Sky Sports.
"Her skill, her instinct, her punch power, energy and ambition - everything about it is ridiculous for someone of such little professional experience."
"Claressa supports her massively," he added.
"Caroline is the heir apparent and it's a big shout to make that call about a fighter in such an early stage of her professional career.
"Fans are excited by it and seasoned professionals just know it.
"The depth of talent that's out there at the moment, you could put Caroline in with most of them because she's very ambitious, she does everything right.
"You talk to her outside the ring, she's so quiet, so polite, so respectful but as soon as the bell goes, she's gone, she's off."
