Pacquiao: Accept Floyd's offer and I'll be laughing stock
Last week Mayweather started his sentence in Las Vegas, having pleaded guilty to domestic battery charges.
Pacquiao has not always seen eye-to-eye with Mayweather down the years, with negotiations over a fight breaking down more than once, provoking a war of words between the two sides - however, the Filipino has stayed magnanimous over Mayweather's plight.
"I'm praying for him," Pacquiao said. "I'm not treating him as my opponent, my enemy or anything. I'm treating him as my friend, my brother. I'm praying for him that all things will be fine for him."
The most recent stumbling block to a bout was the issue of how to distribute the pay-per-view money between the pair: Mayweather wanted to keep all of the cash, and offered Pacquiao a flat $40 million fee, which was refused.
Pacquiao feels there is no way he could have agreed to those terms. "Well, if you are a fighter, would you fight if I give you 40 million and nothing to share in the PPV?" Pacquiao said.
"I would not fight for that. He will be laughing [behind] my back if I do that. It's not a proper negotiation if you're a businessman."
