This coming Saturday night in Moscow, unbeaten cruiserweights Murat Gassiev and Oleksandr Usyk will collide in the final bout of the World Boxing Super Series cruiserweight tournament - with the WBO, IBF, WBA, WBC world titles at stake.
Tony Bellew, who is riding a huge run at cruiserweight and heavyweight in the last few years, would love to get a crack at the winner.
But, he admits that a showdown with former unified heavyweight champion Tyson Fury would be an easier fight - and it would pay a lot more money.
When pondering his next career move, money and risk will have a big influence on what Bellew does next.
"That bout, with all the world cruiserweight belts on the line, would be my number one choice in a heartbeat if all of the options paid the same pot of money. The sad fact is they don't. And this is where you come back to Rachael and the people advising me. We weigh up risk and reward. In this game, you'd be mad not to," Bellew told BBC Sport.
"If I fight Usyk or Gassiev I could be the only British fighter ever to hold all four world belts at once. Lennox Lewis didn't even do it and I love the sound of it. But that would be a very hard, damaging fight. It would have to be the last fight of my career. If it's Gassiev I envisage having to get up off the floor, if it's Usyk I have to ride through a storm at some stage."
While Fury is physically a much bigger fighter, Bellew feels the massive heavyweight makes for a much easier option - because styles make fights.
"If I fight Fury, I could fight again as I don't think it will be hard to beat him and that one fight could potentially earn five times more than Usyk or Gassiev. It's just plain stupid to not think about that," Bellew said.
"Fury is a perfect opponent for me. I still think he's a brilliant fighter and a good bloke. But he has never faced someone quicker, stronger and who has this much to his game. The only things he has over me are height, reach and weight. I can combat those."
