Since joining the sport, Kayla has run through everyone she’s faced … causing some critics to say she isn’t facing premier competition — a claim Harrison takes umbrage with.

“That’s fine, say that I’m fighting cans, say that I’m fighting bums. That’s just ’cause I’m that good. That’s what I want. That’s fine, I want people to say that.”

We also spoke to Kayla about a future super fight with Amanda Nunes (the opposite of a can) … a match MMA fans badly want.

Nunes recently ran through top-contender Megan Anderson … and many experts believe Harrison is the only woman who can give Lioness a run for her money.

Speaking of money … Kayla says it’s gonna take a whole lotta cash — and some other things — before that fight ever happens.
