Khabib Nurmagomedov named his award to return to the UFC and it would cost Dana White a fortune.
The Russian fighter decided to retire from MMA after his victory over Justin Gaethje in October.
He decided to put his gloves down in the middle of the Octagon as a tribute to his father who died earlier this year.
Khabib left the sport with a perfect 29-0 record, but there have already been rumors of a possible return.
Speaking of a possible return, he cited a figure of $ 100million (£ 75million) that would make him consider reaching that 30th victory.
According to Marca, he said: “If you decide to finish, finish.
“But the most likely thing is that Dana will offer me money.
“If, for example, it’s $ 100 million, it would be difficult to make a decision.
“We’ll see what he thinks. I think this is something that will follow me until the end of my life.
There have been calls for a rematch with Conor McGregor or Dustin Poirier, both of whom he beat with ease.
Asked about a potential match with either, Khabib replied, “I’m not interested. I beat them both easily.
