Floyd Mayweather Snr claims he could KO Conor McGregor
Floyd Mayweather Snr has insisted that even he would knock out Conor McGregor if he was fighting him instead of his son.
Ireland's McGregor will on Saturday make his professional boxing debut at Las Vegas' T-Mobile Arena when he faces the undefeated Mayweather in what the 40-year-old says will be his final fight.
The mixed martial artist has cut a consistently confident figure in the build-up to Saturday's fight but is widely expected to be outclassed by a fighter widely considered an all-time great.
Mayweather Snr, 64, himself a former boxer, will again work his son's corner having built his own reputation as a leading trainer and for the same hubris for which Mayweather Jnr is also known.
He became the subject of some of McGregor's pre-fight taunts when the 29-year-old posted a picture of him, claiming it was instead his son, but the trainer has laughed off any chance he has in Saturday's fight, deriding it as a "joke".
"I told him I would knock him out," he said. "I told him when my son has whipped your a***, I will do it next.
"'McConor' should be glad he's been out. If he'd been out of the ring for a week he'd be glad, but I am telling you, you are going to see (how one-sided it is).
"We are going to take him out to the body. That is what's going to happen. I'm not going to call the round but all I am telling you is that McGregor is a dead man.
"All I would say is that he is a clown. And he is fighting a real fighter. But that's why so many people want to see it: because it is a joke.
"That confidence McGregor's got? It's going nowhere."
Asked if Saturday's fight constituted the easiest money Mayweather Jnr has ever made, Snr simply nodded and laughed.
He once claimed that he had the ability to train both Ricky Hatton and Oscar De La Hoya, two of his former fighters, to victories over his son, but asked if he could do so with McGregor, responded: "No I can't. I don't care what I do as a trainer.
"(Floyd's) a grown man. You don't tell a grown man what to do (and whether he should retire after this fight). He's my son so I can suggest it but he doesn't have to do it.
"Overall, I don't think he has to box no more because he has enough money to live the rest of his life the way he wants to live it."
