Kayla Harrison is one of the brightest prospects in women's mixed martial arts. The former two-time Olympic gold medallist is 13-0 since moving to MMA and she was the 2019 PFL women's lightweight world champion.
Since 2019, she has continued to decimate any opponent in front of her. Harrison is on a 12-fight winning streak in the PFL as well as a victory in the main event of Invicta FC 43 over Courtney King.
Despite rumours of a fight against Amanda Nunes, Harrison chose to re-sign with the PFL, penning a contract that reportedly offers her "seven figures per fight".
The fight does seem to be something on the radar of the UFC women's featherweight champion.
Speaking to Trocacao Franca, Nunes spoke of her willingness to fight the undefeated Harrison: "It's not a fight I didn't want. If the opportunity is there and she wants it, cool, I'm in. A fighter needs challenges, people that talk about you and want to fight you.
"If she's going to sign [with the UFC] or not, that's up to Kayla. I'll be waiting.
"That would be the correct way, in my opinion, for her to talk about me, because I'm no longer there [at ATT].
"That's the correct way to say whatever she wants on the mic, to call me out or do whatever she wants, and I'll be waiting for her there. When she signs [with the UFC], I'll be there to defend [my belt]."
Nunes also spoke on how Kayla Harrison's arrival at American Top Team forced her to seek training camps elsewhere.
Nunes added: "There were no girls when I got to American Top Team. I was the first woman to bring two belts and put the women's team in history.
"When Kayla got there and then (Yana) Kunitskaya, it began creating a weird situation for me because that was my territory."
A fight between the former team-mates seems to be inevitable in the future.
With Harrison at ATT, and Nunes now orchestrating her own camp, it promises to big a big-money matchup between two of the best in women's MMA.
