Robert "The Ghost" Guerrero (31-1-1, 18KOs) is convinced that Floyd Mayweather Jr. (43-0, 26KOs) is on the slide. The collide on May 4 at the MGM Grand Garden in Las Vegas. Guerrero is confident enough that he is advising his fans to put down their money because the financial return will be significant. The fight will headline a Showtime Pay-Per-View event. Guerrero will have his third fight at welterweight after unanimous decision wins over Selcuk Aydin and former two-time champion Andre Berto.

"If people bet on me, they're going to make a lot of money, so I suggest they do. I was put in this position not only to humble the boxing world, but to humble Floyd Mayweather. I have a lot of faith that I'm going to go in there and dominate this fight. I see a lot of slippage. I see him slowing down. I think Berto is a lot faster, but the one thing that carries Floyd Mayweather through is his elegance in the ring. His intelligence, being able to change angles. That's what gets him through the day.''
