It’s not inconceivable the winner could receive a title shot, or is at worst one fight away from a title shot.
You’d think a man in that position, with that opportunity, would be happy, but Nguyen is far from happy.
Because his fight with Formiga, one of only three fights on the card that will have real implications for the division, is the opening fight on the preliminary card.
What this effectively means is that a lot of fans won’t get to see two of the best flyweights in the world battle it out, and for that reason, Nguyen is, well, royally pissed off.
He sees it as a sign of disrespect not only to him, but to the entire division.
“I was surprised, I was flabbergasted when the card layout came out,” he said.
“I feel it’s disrespectful to the flyweight division, that’s the only reason I can think of.
“We’re both ranked in the top 10, the winner is a genuine contender for the title, for the belt and they stick us on the prelims?
“There’s a couple of fighters on the main card that have fought once, twice in the UFC, they put them in the main card and we’re stuck on the prelims.
“I’m going to go out there and prove that flyweights can fight and I feel like I’ve already proved that, I’ve never had a boring fight.
“Three of my four wins have been first-round finishes, so I’m not sure what more I can do.
Despite being angry and confused about his position on the card, Nguyen readily admits that for the most part, his life is good at the moment.
He’s been through the best training camp of his life, and he recently got to do what us mere mortals only dream of.
The UFC 221 prelim fight card starts at 12pm AEDT and is live, and free, on Fox Sports.
