Charles Oliveira faces a lot of tough questions as he heads into his fight with Dustin Poirier at UFC 269. The new UFC lightweight champion will be looking to cement his status as the best.

Charles Oliveira has had his heart questioned on many occasions. UFC fights against Max Holloway, Cub Swanson, and Paul Felder have all put his ‘dog' to the test and brought up questions on his heart.

Dustin Poirier recently spoke with MMA Junkie about the subject heading into UFC 269. He doesn't believe you become a champion by chance.

“I would love to for the fight to reach that point where we all find out in front of the world,” Poirier told MMA Junkie. “That’s the goal of mine to get this fight into those deep waters and see who really wants it more, see who is willing to bleed more and leave it all out there because I know I will. No question about it.

“But going to what Justin (Gaethje) said, Dude, I’ve said this. I’m saying the same sh*t over and over again and it feels corny, but when a fighter goes out there – where our last fight is the most important – and he got hurt, came back the second round, and showed championship grit and finished Michael Chandler, a guy who just took Justin to the to hell. So if that says anything, you know, you’re as good as your last fight. He’s a world champion.”
