Manny Pacquiao has laid the groundwork for the world's first-ever £100m fight, against Floyd Mayweather.
The Philippine star, who has won 54 of his 59 professional fights, has raised doubt, however, as to whether Mayweather could guarantee his side of the lucrative purse.
"This is the fight the world wants. Mayweather wants a guaranteed purse so what he has to do is get a promoter who can give them the guarantee," said Pacquiao.
"I don't have problems getting a guarantee because I have a promoter who will give me my guaranteed purse. If he gets a guarantee, then we are going to share the revenue on a 50-50 basis."
Mayweather has the 17,000-capacity MGM Grand booked for May 5, but Pacquiao's team believe they can secure an extra £13m in revenue if the date is delayed to coincide with the completion of a 45,000-capacity arena that is being built in Nevada state.
