Eddie Hearn, promoter for super middleweight world champions Callum Smith and Billy Joe Saunders, says his boxers have not received satisfactory offers to face Mexican superstar Canelo Alvarez.
Canelo is scheduled to return on May 2, as part of Cinco De Mayo weekend, but he doesn't have a dance partner for the date.
Smith holds the WBA's version of title at 168-pounds, while Saunders if the WBO's champion.
In his last fight, Canelo jumped up by two weight classes to score a knockout victory over Sergey Kovalev to capture the WBO light heavyweight title in November 2019.
He later vacated the belt and intends to fight at super middleweight for his next ring return.
Negotiations to face Japanese star Ryota Murata fell apart, and now Canelo has focused his attention on Smith and Saunders - but the two British boxers want better money.
Back in May of 2019, Daniel Jacobs reportedly received somewhere in the realm of $12 million to face Canelo - and now potential Canelo foes are looking for large paydays.
"There is a market rate that has been established, unfortunately for [Canelo's promoters] Golden Boy. Callum and Billy Joe are not even asking for that market rate," Hearn told Sky Sports.
"I don't know which one Canelo prefers. But I do know both Callum and Billy Joe want the fight. The one who gets the fight? Probably the one who takes it for the least money. Canelo has to fight a credible guy. Callum and Billy Joe are world champions. They aren't just being picked off a list. It is a lot of money but it is less than what you have paid everybody else. We feel the same about Anthony Joshua's opponents. The market has changed, and guys are demanding."
