Floyd Mayweather has told Logan Paul to be patient after the YouTube star claimed he was owed millions from his exhibition bout with the ring legend.
Mayweather and Paul clashed over eight rounds last summer with the bout going the distance in Miami.
No winner was announced on the night and Paul has since complained he has not been paid while threatening to sue Mayweather.
But the former undisputed pound-for-pound No.1 has explained why Paul has not been paid in full.
“This comes with the territory,” Mayweather told the The Pivot Podcast. "To them, that’s real money, and I like the YouTubers. The money on the back end though, from pay-per-view, that takes a while. Nothing comes right away.
"I’m still collecting cheques from fights seven or eight years ago. They just hate when the table is turned. Be happy with the biggest payday you ever got in your life."
Paul has repeatedly alleged that he is owed money from Mayweather, going as far as to describe the retired star as a "s***bag".
"It's honestly bull****, [Having] people who aren't a professional promotional company controlling where the money goes... we made that mistake," he told TMZ last week.
"But it's Floyd Mayweather, so before we fought him we were kind of willing to do whatever [and] after the fact we're shooting ourselves in the foot because he's a f***ing s***bag."
Mayweather was expected to bank up to $65million from the exhibition bout after pay-per-view sales were taken into account.
Paul is believed to have earned $14m for just 24 minutes of work.
