Ireland's Conor McGregor says he will knock out long-serving champion Jose Aldo in the first round of the Ultimate Fighting Championship featherweight title fight in Las Vegas on Saturday night.
"I simply see victory, dominance. A clear-cut first round KO," said McGregor.
The Dubliner was originally due to challenge champion Aldo in July in Las Vegas, only for the Brazilian to withdraw citing a rib injury.
McGregor stopped late replacement Chad Mendes in the second round of their contest to earn the UFC interim title.
