In a recent interview, Top Rank's CEO Bob Arum maintained that he had a "good relationship" with Floyd Mayweather Jr. and members of his family. A few days later, Mayweather (45-0, 26KOs) made it known that he would never in his life do any business with Arum.

In the 2006, the two of them had a bad falling out when Mayweather left Top Rank to become a free agent. Over the years, the two individuals exchanged their fair share of verbal jabs in the press.

Some of the comments, apparently, Mayweather never forgot - especially some of the barbs Arum threw in his direction for turning down a fight with Antonio Margarito.

"I don't have a good relationship with him. Why does he want to do business with a coward? When I left, he said something about I was scared of Antonio Margarito and all this, right? Where's he at now and where am I at? They claimed [Jos eLuis] Castillo won the fight; where's he at now and where am I at? We can keep going on and on. All I gotta say is where are they at now, and where am I at? It's so crazy; I be looking at fighters like Pacquiao. I know Rob Arum gonna eat, Michael Koncz gonna eat; all of them are on a percentage basis. Guess what! Michael Kon...What's his name? Michael Con-Artist? Michael Con-Artist wouldn't be my manager if I was in the boxing game," Mayweather said in an interview with Ben Thompson of Fighthype.com.

"What's so crazy is a long time ago, Pacquiao should have got with Al Haymon and we would've got his career together. But sometimes, they don't listen. A hard head makes a soft ass. When I gave him the opportunity to fight me, he didn't take it, and then, he was sleeping on that MGM canvas. I don't know how that feels, but he can take it every which way, if he feels more comfortable laying on his face or on his back. In life, it's about moving forward."
