Dustin Poirier is set to take on Charles Oliveira in a very exciting fight at UFC 269. The winner will walk away as the undisputed UFC lightweight champion.

Heading into the bout at UFC 269, Charles Oliveira has had a reputation for being a ‘quitter.' Many point to his fights against Donald Cerrone and Max Holloway.

Many agree he's changed as a fighter heading into UFC 269. You can include Dustin Poirier as one of those people.

“If it’s in there, we’ll find out,” UFC 269 main eventor Poirier told MMA Fighting’s Damon Martin in a recent interview. “But I can’t bank on that. We’ll see. He showed grit in his last fight against Chandler. He got hurt, almost got finished, came back and knocked the guy out. Your last fight is the one I go off of and he showed championship grit.”

“I’ve been watching that guy a long time,” he added. “We’ve both been in the same waters, [145, 155 pounds] for the last decade in the UFC. There’s a list of guys when they won the belt was really special to me and he’s on that list. [Michael] Bisping’s on that list. Robbie Lawler’s on that list. Underdogs.

“Of course everybody’s fighting against adversity but the guys who were counted out a couple times and made it happen. I’m trying to add my name to that list. That’s the goal here this weekend.”

UFC 269 will be an opportunity for both men to show what they are made out of. The fight is a very high-level contest and will rightfully determine who the best lightweight fighter in the world is.
