Cris Cyborg Still Wants Amanda Nunes Rematch 3.5 Years After Loss

It's been nearly four years since Cris Cyborg lost to Amanda Nunes ... but she STILL wants her revenge -- telling TMZ Sports she's still gunning for a rematch with The Lioness.

Cyborg initially lost to the UFC legend in December 2018 -- and she's clearly not over it ... explaining to us out at LAX that she'd love to get another crack.

The 36-year-old says she initially wanted to run things back right after the fight 3.5 years ago -- but wasn't able to make it happen.

Now, she tells us she's down to get it done in any way -- even if that means making the fight happen on their own.

In the meantime, Cyborg is set to square off with Arlene Blencowe at Bellator 279 on April 23 ... and she says she's excited to try to get the win even though she's already beaten Blencowe back in Oct. 2020.

As for how much longer Cyborg plans to fight ... she tells us she's still planning to be around for a while -- hoping to get three more years in.
