Nate Diaz, one of the most badass and beloved fighters in MMA history, tells TMZ Sports he wants to fight Dustin Poirier ASAP -- in what'll be his last fight ever -- before retiring from MMA.
We talked to the 36-year-old superstar from Stockton at Shaq's Fun House party in L.A. Friday night ... and asked Nate, who has 1 fight left on his UFC contract, who he wants to be his final opponent.
"I would like to fight Dustin Poirier. Like now. Like I've been trying to. If there's any mix-up it's him, and them, and the game," Diaz said.
"I want the fight now. What's up Dana White? Let's get this retirement fight cracking so I can get out of this fight game. I'm done with it."
It's bittersweet for Nate fans ... and he's got millions of 'em. A fight with Dustin would be big ... especially since Diaz says it'll be the last of his future Hall of Fame career.
A career where Nate's beaten everyone from Conor McGregor to Anthony Pettis and Donald Cerrone ... all while being one of the most real dudes in sports.
We asked Nate ... how would the fight with DP go down?
"He ain't doing s*** to me. I'll tell ya that much," Nate said.
Bottom line -- Diaz has made it clear he wants to fight Dustin. Now, the ball's in Poirier's court.
As for Nate's future ... even though he won't be fighting, he'll still be around. He's got a successful clothing label, Represent, and his protege, undefeated Nick Maximov is one of the UFC's best prospects.
