The retired striker does not exclude the possibility of taking over the governing body, but insists that his current focus is helping preparations for the showpiece event
The 35-year-old, who retired from football last year, is heavily involved in preparations for the upcoming World Cup finals after taking up a position in the Local Organising Committee (LOC).
Despite previously saying that he had no interest in the job, the retired striker has now admitted that he could run for the CBF presidency after the World Cup.
"I want to start a political career in football," Ronaldo told Folha de Sao Paulo. "I do not know if I would be a candidate for the CBF presidency, but I would accept it.
"I see a big margin for improvement in football. I think that even though I gave such a big contribution when I played football, I can be much more useful off the pitch.
"I need to have full knowledge of CBF's statutes. Thanks to God, money is not my focus or my objective.
"As such, I can do the kind of things which give me pleasure, like accepting LOC's offer.
"After the World Cup, we will see. It is too early to talk now. I want to be play a big part right now, when this event takes place."
Ronaldo also said that he plans to meet with new CBF president Jose Maria Marin, who has taken over the governing body following Ricardo Teixeira's resignation, during the course of this week.
