Amanda Nunes is considered by almost everyone to be the greatest female fighter of all time... so, that begs the question, what's Julianna Pena if she defeats the G.O.A.T. for a second time?! We asked her. "I don't know anybody else in this division or the sport that has been able to have the resume that Amanda has made so it's definitely worthy of being called the greatest of all time. But, now that I'm here, I am also being worthy of being called the G.O.A.T slayer.”
