WBO welterweight champion Jeff Horn has been urged to fight in the United States by a top Australian agent.

This past Saturday night, Horn captured the World Boxing Organization welterweight title with a twelve round unanimous decision over eight division king Manny Pacquiao.

A crowd of over 51,000 went wild when the local man was announced as the winner at the Suncorp Stadium in Brisbane, Australia

Pacquiao, 38, may exercise an immediate rematch clause, but he doesn't want to face Horn again in Australia. He would like the fight to take place in the Philippines or on neutral ground, like Las Vegas.

Pacquiao, who is also a senator in the Philippines, regained the welterweight world title belt he lost to Mayweather when he knocked Jesse Vargas down in the second round and cruised to a unanimous decision in November.

He decided to make make his first defence against Horn after a big-money fight with British star Amir Khan in the United Arab Emirates fell through earlier this year.

Australian celebrity agent Max Markson believes Horn can become an even bigger star is he begins crossing the ocean to fight in America. Pacquiao was a hit his home country, but became a superstar when he started campaigning on U.S. soil.

"He'll pick up money outside of the ring, he will get sponsorship, but it won't be anything like the money that is attracted for the pay-per-views in America," Max Marston told 9news.com.

"He's got to go fight in America and if he does that, he fights big names and he wins, the world is his oyster."

If a rematch with Pacquiao fall through, Horn has also mentioned the possibility of unifications with IBF champion Errol Spence and WBA champion Keith Thurman - both of them are based in America. And he also targeted the biggest prize of all, a showdown with the comebacking Floyd Mayweather Jr.
