Rivaldo, 43, is contemplating making a full comeback in order to help the club he presides over, Mogi Mirim, escape the relegation zone of Brazil's second tier of football.
The World Cup winner says he still trains with the club regularly but doesn't plan on being a full-time player or anything of that ilk.
He said in a statement (h/t Al Jazeera):
Once again, I sitll sacrifice my family for the good of the club but I hope to see our team in a more worthy situation in the competition.
I stopped playing professionally 15 months ago but, if my knee is OK, I could help in some games, but that is something the training sessions will help me decide.
