Former two division champion Marcos Maidana made a lot of headlines earlier this year when he announced his comeback to the ring. He signed a multi-fight deal with Premier Boxing Champions to guide his return.

Maidana had been out of the ring since 2014, when he lost a twelve round decision in his rematch with Floyd Mayweather.

But he made just as many headlines last month when he announced that his comeback plans were shelved and he was going to remain retired for good.

BoxingScene.com reported that Maidana received several financial advances to assist him with his comeback expenses, but there was a disagreement when Maidana began pushing for a much bigger advances of money.

And Maidana now admits money was the root cause of his decision to remain in retirement.

"Yes, it's [my decision is due to] economics. Training expenses, and those things. It wasn't [something agreed upon] in the contract, but it was verbal. They said they were going to take care of things.. training expenses, vitamins, etc., and I'm taking care of it out of my pocket," Maidana told Popular.

"They deposited something ... They gave me $10,000 once ... After others ... another 10, I think. It was $30,000 [in total] I think, and then they gave me another deposit, but I do not know how much. I did not notice. But $150,000 was what they had told me they were going to give me. And while I do not need money, what I am most worried about is a person [giving me their] word. I also have to pay my people, my coaches, physical trainer, everything. And I'm putting it out of my pocket."

There were concerns on the PBC side, that Maidana was not serious about his return and would potentially take his large advance and just return to Argentina.

"Yeah sure, its OK. They sure thought that. It is true. But for that reason, if there is no confidence, I prefer to leave everything as it is," Maidana said.

"I like the sacrifice. I do not need money. It all started as a game with those statements I made about going after Mayweather. But then it was serious. And there were $15 million dollars in total and the possibility of fighting against Pacquiao, that was what I liked. What really tempted me was the sporting challenge against Pacquiao, that's why I accepted."
