Top Rank's CEO Bob Arum was never a big fan of the Ultimate Fighting Championship [UFC] - which is the top organization in mixed martial arts.

Arum and UFC President Dana White have been engaged in a feud and traded words for several years.

Most recently, Arum was very critical of last month's pay-per-view which featured UFC superstar Conor McGregor making his professional debut as a boxer, against a returning Floyd Mayweather Jr. White went wild over Arum's comments and verbally erupted in the direction of the veteran promoter.

Several years ago, Arum suggested that most UFC fans would love a fighter like Kelly Pavlik - because the veteran promoter stated that the UFC fans were made up of white skinheads.

Last year, Arum made a mountain of headlines after stating that "fans of the UFC" were "Donald Trump supporters."

"Well the UFC, they've done a great job promoting, but one thing I've said, and I'll say again, I'll say it straight out — the fans of the UFC are Donald Trump supporters. The fans of boxing support Hillary [Clinton], Bernie [Sanders], and maybe John Kasich, so there's a difference,” Arum said.

"The preponderance of UFC fans are Trump supporters — white males who are desperately afraid that this country in 20 years will be a non-white majority country. And that's why they're reacting, and that's why they're supporting an imbecile like Trump. And maybe that's why they like UFC."

In a recent interview with ESPN Deportes, Arum suggested that UFC is boxing's main enemy - and in order to beat the UFC the main promoters in boxing would have to put their rivalries aside to work together in order to make the best fights.

"We have an enemy, we have a villain, and it's the UFC. If we all work together we can beat the UFC, which is a sport that can not be compared to boxing," said Arum.

"I remember many years ago when boxing was a sport that received the same attention as the other major sports in the United States... there was no way that you did not have a boxing reporter [working at every major newspaper] - and with the collaboration of everyone we can bring boxing back to the position that it deserves."

Arum's company recently signed a multi-year television deal with ESPN. And Arum stated that he doesn't plan to exclude other promoters from showcasing their talent on the network. He's willing to open the doors to everyone to bring the best fights to ESPN.
