Finkel said Wilder is looking for his next opponent after his victory against Robert Helenius in one round last October.
Although both fighters were in talks to face each other in 2019 with Wilder’s team reportedly offering £40m ($50m) to stage the bout in Las Vegas, Joshua’s promoter Eddie Hearn called off the negotiations after failing to see evidence of the prize.
At the time the heavyweights both held world title belts – Joshua had the IBF, WBO and WBA belts while Wilder was the WBC world champion.
But now both men are looking to rebuild their careers after damaging losses, so with the pressure off the possibility of a match-up has re-emerged.
Joshua and Wilder were linked to a highly-lucrative and high-profile card in Saudi Arabia last week, with Hearn claiming the £323m could even see the British star and his American rival face each other on the same night as Tyson Fury vs Oleksandr Usyk.
Finkel told Sky Sports that Wilder has now talked up the chances of a fight happening in Saudi with Joshua.
