UFC president, Dana White, was optimistic about the prospects of a Floyd Mayweather Conor McGregor boxing match occurring.

White has traditionally been pessimistic about the possibility of the two superstars meeting in the square circle, citing the UFC contract of McGregor and the boxing component of the match up as two detractors. In January, White used cryptically threatening terms when speaking about McGregor attempting to bypass his UFC contract in order to facilitate the fight. During an appearance on Conan on Wednesday, however, White seemed to indicate that only formalities stood in the way of the fight happening.

“I do think it’s going to happen,” said White to late night host, Conan O’Brien. “I think it’s going to be a tough deal, because, obviously, there are a lot of egos involved in this deal and a lot of people, so that always makes it tougher. On the flip side, there’s so much money involved, I just don’t see how it doesn’t happen.”

White did qualify his optimism, pointing to how long it took Mayweather to agree to fight legendary boxer, Manny Pacquiao. Many believed that Mayweather waited strategically until Pacquiao had left his fighting prime. According to White, it may take Mayweather longer to agree on a deal with McGregor, who is 28 and the UFC lightweight champion.

“A lot of things make this fight intriguing,” continued White. “Conor McGregor is huge. He’s in the prime of his career. Floyd is 40. Floyd has always had problems with southpaws; Conor is a southpaw, and Conor hits hard. When he hits people, they go. Floyd is definitely not knocking him out. That’s for sure.”
