Khabib Nurmagomedv has claimed he is prepared to go to prison if it means finishing the job on Conor McGregor.
The pair's bitter rivalry appeared to be settled in the UFC Octagon last October when the Russian won by fourth-round submission.
But as he prepares for his return against Dustin Poirier at UFC 242 next weekend, the lightweight champion revealed the wounds remain fresh.
And Nurmagomedov went as far as to say he is willing to fight McGregor and his team on the streets.
"Even (the October fight) did not finish it," Nurmagomedov told ESPN.
"Just to smash people is not enough. I talk about just smash only him? It's not enough. We have to smash all his team. This is what I think before the fight. This is what I say to my team, 'Hey, tonight, we're going to war; this is not about a fight.'
"It will never be finished, ever. Even if we see (each other) somewhere, we're going to fight, 100 percent.
"It doesn't matter if someone go to jail or something like this. I'm not scared about this - they go to hospital and we go to police. That's it."
McGregor has long called for a rematch with Nurmagomedov if he successfully defends his lightweight belt.
But the champion has no intention of gifting the Irishman a second shot at the 155lb belt.
"This guy has to come back and make nine or ten-fight win streak, then we gonna fight," he added.
"Maybe people who watch this interview, they think, 'Oh, he think about this, but when UFC ask this guy to fight Conor for millions of dollars, this guy is gonna take it.' No; fight, come back and show who you are.
"I want to fight real guys - Dustin Poirier, Tony Ferguson, maybe if one of the greatest athletes ever, Georges St-Pierre, wants to fight. I want to fight those guys. I don't want to fight with a guy who never wins."
