Radio Interviewer: What kind of money is there in the sport? Is there a lot of money in it?
Alexander Gustafsson: No, I wouldn't say that.
RI: There isn't?!
AG: No, I earn enough to get by and so that I can train full time, but that's it. I can't buy a new Porsche.
RI: But if you had beat Jon Jones, how much more would you have earned? Can I ask you that?
AG: I don't know the answer to that question but it would have been considerably more. Then I could've bought a brand new Porsche.
On Saturday Gustafsson made two $50,000 'of the Night' performance bonuses, plus his show money plus his win money, plus who knows, so presumably his financial situation is improved at present.
