Former five division world champion Floyd Mayweather Jr. has lashed out at UFC president Dana White - as they continue to trade words over the financial terms for a boxing match between Mayweather and UFC lightweight champion Conor McGregor, who have been going back and forth in the media for the past year.

Last week, White offered Mayweather and McGregor $25 million each plus a cut of the pay-per-view revenue. Mayweather called White a "f***ing comedian" in response to the offer.

“I don’t want to talk to Dana White. Remember, Dana White he was a player, he was a boss, but he was a small boss. The big bosses were the Fertitta’s but then the Fertitta’s choose to sell the UFC so Dana is just an employee. I like Dana White, I don’t have anything against him but I can remember Dana White used to hang around me and Jeff Mayweather and carry my bags,” Mayweather told Fighthype.

“Dana White, I remember you used to carry my bags. And remember Dana White, I showed you love, you used to have the Bullenbeisser (boxing apparel) patch I wore on my trunks for you Dana. I’ve always been good to you but all of a sudden he cut his head bald and he’s such a tough guy. He’s such a tough guy. All I’ve got to say is this — why every time Conor McGregor goes out there and fights, Dana White is still an employee but Dana White makes more money than Conor McGregor when McGregor goes out there and fights?”

Bullenbeisser was a boxing apparel company owned by White and Mayweather wore the gear for his first four fights as a pro, having turned professional in the wake of a bronze medal performance at the 1996 Olympics in Atlanta.

“The last time I made $25 million, actually I made more, but the last time I made $25 million was 10 years ago. I’m not bragging or boasting, I’m just telling the truth,” Mayweather said. “I’m appreciative and thankful. $25 million is still great money."

“For the last how many years, my guaranteed lowest would be $32 or a little bit over $32 (million) that’s my lowest but you’ll also note that in the Canelo (Alvarez) fight, I made over $100 million in that fight. In just two fights, (Manny) Pacquiao and Canelo, those two fights somewhere upwards of probably $400 million or better. Sponsorship money leading up to the Pacquiao fight, that week I made somewhere between $25 to $30 million.”

“These are my numbers. They can say ‘Floyd is lying’ all that they want to, if I was so desperate and hurting for money, I would come back.”
