This work seeks to better understand the Brazilian soccer fan, mainly from Rio de Janeiro, to know what makes him a fan of some team, also understanding his buying habits. The study raises an important database that constitutes platform for the construction of strategies that aim to improve the acquisition of fans by the Clube de Regatas do Flamengo, focus of the study. A field survey was conducted through a questionnaire. The results presented relevant aspects to understand the reasons why Flamengo does not reach as many fans as its potential allows. The conclusion of the work is presented as a valuable subsidy for professional managers linked to the Brazilian football market and may also be useful to the marketing department of the red-and-black football club from Rio.
