Even if they are arch-rivals stretching back to the 1970s, Don King and Bob Arum both believe making a Manny Pacquiao-Floyd Mayweather fight will be as easy as reciting the alphabet.

“Me and Bob would get that fight done in two shakes of a lamb's tail,” King told Dan Rafael of ESPN. “If I was there working with Bob Arum, this fight would have been history. It'd be ready now and we'd be talking about how we gonna promote. It wouldn't be nothing put a piece of cake. But even then it would be so much bigger that what it would be if he were to make with Golden Boy or Al. They cannot make the fight as big as Arum and I can make it. They are not in the class of a Bob Arum.”

Mayweather recently spent some time with king in Florida and it has been reported that both touched the issue of making a fight with Pacquiao.

King, who teamed up with Arum in staging the 1975 Thrilla in Manila, even said that such a fight could generate as much as $200 million in revenue.

Arum said last week that he doesn't see any problems dealing with King despite their history of animosity.

Efforts to put together a Pacquiao-Mayweather fight failed for the second straight time last month, leaving fight fans in disgust. In the negotiations, Mayweather was represented by Golden Boy Promotions.

Pacquiao, in his column in a leading tabloid, said he is asking King and Mayweather to come to terms right away so a fight between them on Nov. 13 can be made.

Arum has penciled Pacquiao to face Antonio Margarito on the same date but will not sulk if King and Mayweather decide to join hands and finally get things done for what King calls as the “biggest fight in the universe.”
