The Predator shocked the world by dropping the heavyweight world champion in the third round of their blockbuster clash.
But he left Saudi Arabia disappointed as Fury scored a controversial points win.
However Ngannou did not leave empty-handed as he picked up the biggest cheque of his fighting career.
Martin revealed the Cameroonian received a bigger purse for the contest than in all of his previous UFC fights combined.
He told The MMA Hour: “It’s up there. I would say up there. Multiples upon multiples upon multiples [more than the UFC],
“I saw a statement, and let me make this clear — someone said, I forget who it was, that, ‘Oh, between the fights that he missed out on or whatever, he still fumbled the bag.’
“You’re absolutely incorrect. I know what the pay-per-view numbers look like. I know what he would have gotten paid [in the UFC].
“Still, you add up all of that, whatever you want to say, no, Francis did not fumble the bag. He’s gotten, [with] just that one fight, more than everything he could have made [in the UFC] combined.”
Ngannou, 37, had 14 fights in the UFC – one of which came as a defending champion.
