Manny Pacquiao and Chris Algieri are on a two-week, globe-trotting tour to promote their welterweight title fight in November, but the match the world truly wants to see looks further away than ever.
When Pacquiao met the press in Macau on Monday, questions about his elusive megafight with the undefeated American Floyd Mayweather met with a sharp response.
"Who's that?" Pacquiao joked, when Mayweather was mentioned by reporters.
Pacquiao's hall-of-fame trainer Freddie Roach was less jovial, conceding bluntly that the two boxing legends, both in the twilight of their glittering careers, may never be seen in the same ring.
"We can't waste our time waiting for him," Roach told AFP. "We've done everything we could to make that fight happen. It's like, we're available if he's interested in it, but again we can't sit around waiting for him."
Eight-division world champion Pacquiao's next date is a World Boxing Organization welterweight title defence against the undefeated WBO junior welterweight title-holder Algieri on November 23 in Macau's Cotai Arena.
In 2010, Pacquiao and Mayweather were close to agreeing a fight between the two greatest boxers of their generation, which could potentially have generated a record $300 million dollars in pay-per-view revenue. But it fell through because Mayweather was unhappy with Pacquiao's drug-testing procedures in training.
That issue receded after Pacquiao agreed to Olympic-style testing, and the Filipino icon expressed his frustration that a Mayweather clash has still moved no closer after getting his career back on track with comprehensive victories in the past nine months over Brandon Rios and Timothy Bradley.
"The possibility to fight with him, you know, the question is not for us," Pacquiao said. "It's for them because any time we are willing to fight, any time. I think that question belongs to them, their camp."
The biggest hurdle that remains – and it is a huge one – is the animosity between Pacquiao's promoter Bob Arum of Top Rank and Mayweather's Golden Boy promotions, who have deals with rival pay-per-view networks HBO and Showtime, respectively.
Arum admitted on Monday that HBO and Showtime had to "find a way to promote and satisfy both sides from a legal basis", before the biggest money-spinning fight in the sport's history could be agreed. He added the TV rivals had expressed a desire to achieve a deal, but conceded that the final decision lay with Mayweather and Golden Boy who have shown no intent of late to get around the table.
"With Showtime and HBO wanting the fight and Manny wanting the fight, there is one little step to take and that's to see where Floyd stands," Arum said.
Even if there were to be a sudden thawing of relations between the two camps, the earliest a fight could take place is late 2015. Mayweather has a rematch against Marcos Maidana next month and Pacquiao faces Algieri in November before a likely fifth blockbuster fight against Juan Manuel Marquez, who knocked out Pacquiao in 2012.
"Hopefully we can put Marquez in with Pacquiao next year," said the 82-year-old Arum.
But the reality is that Mayweather-Pacquiao may never come to fruition. Pacquiao is due to retire at the end of his current deal with Top Rank in 2016, when the congressman from Sarangani will be 37. Assuming Mayweather, who is also tipped to fight Britain's Amir Khan early next year, remains unbeaten, he is unlikely to want to risk his dream of equalling Rocky Marciano's career mark of 49-0 against 'Pacman' this time next year.
That just leaves one, extremely remote, possibility for the two to appear in the same ring. Should both remain unbeaten until the end of 2015, they could provide a fitting end to their careers in early 2016 by settling the argument once and for all.
A victory for Mayweather would take him to the magical 50-0 mark, a win for Pacquiao would cement his place as one of the greatest boxers not just of his own generation, but of all time.
The world wants it, Pacquiao wants it and, according to Arum, HBO and Showtime want it.
The lucrative pay-day would dwarf anything the sport has seen before.
It's a quarter-of-a-billion-dollar question that only 'Money' Mayweather knows if he can be tempted give the right answer.
