Ultimate Fighting Championship welterweight titleholder
Both are current UFC champions ranked No.1 in their weight classes. Each are considered amongst the top pound-for-pound fighters in the world. They're in their primes. This is a mega-fight.
"He's the guy that I want to fight. He's my best challenge right now, and he's the guy that I want to fight," St. Pierre told MMAWeekly.com recently. "I have to fight guys like B.J. to make myself a legend in this sport.
"When you're a world champion you have to set your goal even higher. I don't want to fight to be champion anymore because I'm already champion. I want to fight to become a legend in the sport, and that's what this fight will give me," the Canadian added. "I think if you ask somebody who's the best pound-for-pound in the world, a lot of people would say it's B.J. Penn. So, for me, it's a great challenge as well."
In the thirty-two months since their first encounter, the two have improved and are different fighters with different attributes. "He has improved a lot. I have improved a lot," said St. Pierre. "So, it's going to be a clash."
Asked what's different this time heading into a bout with Penn, St. Pierre stated, "Every fight is always a problem. B.J. Penn is a big problem, but I think that I'm going to be able to solve it.
"I'm more experienced and way more skilled than I used to be," added the UFC welterweight champion.
