Carl Frampton and Scott Quigg have both claimed to be the man who can beat Guillermo Rigondeaux after their super-bantamweight world title unification fight on Saturday.
Rigondeaux, who is without a world title but still generally regarded as the division's No. 1, looms large over the Britons' mouth-watering clash in Manchester this weekend.
The winner of the 50-50 fight will progress to meet Rigondeaux (16-0, 10 KOs) later this year to decide the best in the division.
The classy Cuban, who won Olympic gold medals at the 2000 and 2004 Olympic Games, has accused both Belfast's IBF champion Frampton (21-0, 14 KOs) and Manchester's WBA king Quigg (31-0-2, 23 KOs) of ducking him - but both Britons insist they want to fight him later this year.
"I've always said I'm open to fight Rigo, I see him as the king of the division but I feel I've got the beating of him," said Frampton, 29. "I would prefer it on home soil especially when you are fighting someone as good as Rigo, but I'm happy to make the Rigo fight.
"It's a very difficult fight but I feel I'm the only super-bantamweight in the world who has the skillset, the ability and the balls -- it'll take a big set of balls -- to beat Rigo, I really do. I feel I have the ingredients to beat him."
Rigondeaux is a former WBA and WBO world champion who lost his grip on those titles through inactivity, but the 35-year-old is still the WBA's 'Champion in Recess' and the WBA has declared the winner of Frampton-Quigg must face him by July 27, 2016.
Maimi-based Rigondeaux ended nearly a year in exile when he out-pointed Drian Francisco in November and, interestingly, returns to action not far from Saturday's fight a couple of weeks after Frampton-Quigg when he boxes local hero Jazza Dickens (21-1, 6 KOs) at the Echo Arena in Liverpool.
Quigg, 27, suggested he would be willing to immediately relinquish the IBF belt if he beat Frampton and was then obliged to make a mandatory defence against Japan's Shingo Wake (20-4-2, 12 KOs) next.
"Rigo, our paths will cross because I'm 100 per cent sure I will get the job done against Frampton," Quigg told ESPN.
"I want to keep challenging the best and the WBA have ordered the winner of the fight against Frampton to fight Rigo next. The IBF want the winner to face Shingo Wake next, and it's a tricky situation because I don't want to give up the WBA belt because I've been champion for a while.
"But I'm here to fight the best and I'm not going to relinquish the WBA belt to avoid someone. I need to focus on becoming unified champion first and I've got a tough fight ahead of me before I can think about anyone else."
