Fallon / AFP via Getty ImagesKayla Harrison says Amanda Nunes fight is the real GOAT matchup in response to Ronda Rouseys commentsKayla Harrison has already fired back at Ronda Rousey following a recent rant, telling the former UFC star that if she wants to settle things, they should meet in the cage.Rousey continues to promote her upcoming fight with Gina Carano as one of the biggest in womens MMA history, but that hasnt changed Harrisons stance.The reigning bantamweight champion is set to defend her title against Amanda Nunes once she returns from injury and used that fight as another way to push back against Rouseys claims.She took to social media to address Nunes directly, posting on X: Good morning @Amanda_Leoa (Nunes)! I cant wait for us to have the greatest fight of all time and take womens MMA to a whole new level. The best vs. the GOAT!I dont think it was meant as an insult, she said. I think what she was trying to say is there are so many great female fighters now that its hard for anyone outside of Kayla or Amanda Nunes or maybe someone else, like Alexa Grasso now, who knows.Nunes and Carano werent set for Netflix 3 until recently after Juliana Pea pulled out due to injury. That led fans and fighters alike suggesting it shouldnt headline over Harrison vs. Nunes.In March 2024, Harrison mentioned she was waiting on a CT scan result that would determine when she could resume training after neck surgery earlier in the year.Read more:Ali Abdelaziz responds strongly to Ronda Rouseys criticism of Kayla HarrisonRonda Rousey reveals minimum pay for Netflix MMA debut, says UFC cant say the sameKayla Harrison responds to Ronda Rouseys callout with a challenge of her own
