"There are also interesting opportunities around the world - there are guys like [Alexander] Povetkin in Russia and there's a Japanese heavyweight [Kyotaro Fujimoto] in the top 10 and I don't think any Japanese heavyweight has challenged for the world title so... you could break new ground in a city like Tokyo."
Higgins said he and Parker were not neglected the United States market, with American Deontay Wilder, the current WBC champion, also in the mix. Bob Arum, the veteran Las Vegas-based promoter with whom Duco have a close working relationship, recently signed what Higgins described as a "ground-breaking" and exciting deal with ESPN.
"Joe is a pay per view star in New Zealand, at home, but he's got work to do offshore," Higgins said. "Our job now is to make him a pay per view star in the UK and United states, one market at a time. To be a pay per view star in the UK you need to knock out Englishmen on British television. If Joe can beat Fury - a name known the world over in boxing circles - if he can put Fury on his back it's a turning point, the world is his oyster."
Higgins said his recent trips to London, where he met Joshua's promoter Eddie Hearn, a man who also manages potential rivals Tony Bellew and Dillian Whyte, and Manchester, where he met the Furys, were extremely valuable.
"I had a series of business meetings, which Joseph didn't attend. There is misinformation out there that Joseph was meeting with Hearn and Haye, whatever, that was my job and we had some good discussions."
Chief among them would have been a fight against Joshua, but there is also a strong possibility that should Parker beat Fury his next opponent will be Tony Bellew in the United Kingdom on December 16.
A bout against the charismatic Bellew would probably catch the imagination even more than a Fury victory and would help boost Parker's profile before a mega-fight against Joshua.
"We see Joshua as beatable. He is deservedly seen as the man to beat and people will look at the size of him and the muscle. But there are little chinks in his armour. Klitschko put him on the canvas, our experts reckon he's slightly predictable. Joseph has never been off his feet, he's very quick, it's not about muscle."
Higgins added: "I want to play respect to Klitschko. Retiring is a hard call and it would have been tempting to take big, big money against Joshua again. It's wise and it's nice to see heavyweights base that decision on their own terms rather than being battered out with multiple losses in a row."
