Floyd Mayweather's fight against Conor McGregor is a farce, says former world heavyweight champion Lennox Lewis.
Irish UFC lightweight champion McGregor, 29, will make his boxing debut when he faces undefeated American Mayweather on 26 August in Las Vegas. Mayweather, 40, will surpass fellow American Rocky Marciano's perfect record of 49 fights without defeat should he overcome McGregor.
It's going to be a relentless week. Too many people are treating it like a comedy carnival. On the night I think it will be a lot more serious than people think. I think the laughter will stop in Las Vegas, probably around Wednesday.
McGregor is a guy who was nowhere four years ago. Now he can earn hundreds of millions of dollars. He got there because he is absolutely driven.
I've seen his fights, I think he likes hurting people. So there will be dark undertones next week. Anyone who thinks Mayweather doesn't have a nasty, dark side has been living in a cave for 30 years.
I believe McGregor has picked up a lot from Mayweather. If you are skint like he was five or six years ago and you are seeing a guy like Mayweather who has been making it rain throwing dollar bills in the air, of course he is copying that.
He has wanted a bit of that. I can imagine McGregor before he goes to bed at night doing a few Mayweather moves in the mirror.
