"I've come through a lot tougher than any of these have".
However, McGregor, the 29-year-old from Dublin, insisted he was ready to stun the world of combat sports by upsetting Mayweather, who would improve his record to a flawless 50-0 with a win.
Sports fanatics can enjoy the Pay-Per-View screening of the fight at the Kia Theatre in Araneta Center, Quezon City. "We're going to compete and give you what you want to see", he said.
'From day one, everything that my dad taught me, I still know to this day - every combination that was taught to me, I know.
McGregor is exuding confidence as their mega-money clash draws closer despite the odds being stacked against him.
"I believe he'll be unconscious within one round".
"Just being on the same card as Conor McGregor changes people's lives".
Move over, Ted DiBiase and the Million Dollar championship. "I am going to do that for him". I've sparred him over a 1000 times. With 8oz gloves I don't see him surviving. "I have adapted perfectly to boxing, I am very pleased and ready", he added.
"After I complete victory on Saturday, I'm planning on taking on both sports".
McGregor, 29, will be making his professional boxing debut Saturday.
He has sparred with, among others, boxers like the respected Paulie Malignaggi, and under the observation of boxing referee Joe Cortez, but relied on long-term coach John Kavanagh to hone his technique.
It's half-fight, half-spectacle, a bout that matches a UFC star who has never boxed against a masterful ring technician with a record of 49-0. "I love the fight game more so than the MMA type of stuff. It's not needed", he said. "There was no need for it". Mayweather has had some difficulty in the past adapting to southpaws, so there might be some openings for McGregor to land some shots early.
McGregor, on the other hand, averaged 8 minutes, 38 seconds in his last 10 UFC fights. "You should have left me where I was".
McGregor was far less effusive in his compliments but after months of mercilessly attacking Mayweather said he welcomed the pause in hostilities.
