Floyd MayweatherFloyd Mayweather is considered by many to be one of, if not the best, in the boxing world. As he gears up for his May 1st showdown against Suger Shane Mosley, the undefeated boxer is letting it be known that his skills are top notch .. and Mosley, Mayweather, and even all-time great Muhammad Ali can’t f… with him.

In a telephone conference call this week, Mayweather let media outlets know just how much he is feeling himself.

Vibe.com was on the call. This is what the boxer had to say:

On Mosley: “Shane is a solid welterweight. But I don’t know where I would put Mosely. I can’t see how a guy could call himself great or putting himself as a future hall-of-famer. This is a guy … we don’t know how long he was taking enhancement drugs. He’s been around the sport for a long, long time. He’s done some things in this sport. But he’s a fighter that always worries about landing one big shot. And I worry about being smart and winning. When Shane punches, a lot of times he closes his eyes. We are two totally different fighters.”

On Manny Pacquiao: “Manny Pacquiao struggled twice with [Juan Manuel] Marquez, which we know he really lost. And we know he’s been knocked out twice. He’s been out-boxed by Erik Morales, but they still give him ‘Boxer of the Decade.’ So that’s something I don’t understand. He beat a Miguel Cotto that was stretched by me. I’m trying to find out what it really is. All I’m saying is if you are a clean athlete, take a test. Show the world. I’m a natural.”

On greats, Ali and Sugar Ray Robinson: “I take my hat off to them. I got respect for Sugar Ray Robinson; I got respect for Muhammad Ali. But I’m a man just like they’re a man. I put on my pants on just like they [do]. What makes them any better than I am? Because they fought 1,000 fights and my era is totally different. It’s pay-per-view now, so things change. It’s out with the old, in with the new. Muhammad was one hell of a fighter. But Floyd Mayweather is the best. Sugar Ray Robinson was one hell of a fighter, but Floyd Mayweather is the best.”

Mayweather will take on Mosley at the MGM Grand in Las Vegas for a welterweight pay-per-view super fight on May 1st. For more info, visit HBO.com/Boxing.
