OSAI Sport Club FutSal is one of the main amateur futsal teams from the east side of São Paulo, Brazil. It was founded on April 20, 1981, in the Grimaldi neighborhood.
As years passed by, the team established itself in the amateur league, becoming known for always exhibiting high quality, artful and energetic presentations. Since then, the team restructured itself in order to comply with its needs and those of its fans, who always accompanied, rooted for and encouraged the team. The team has amassed more than 300 trophies in many festivals and championships. Many of those trophies were given to its more diligent fans. The team and its fans are, in fact, a big family – not only because many of the fans are related to a player, but because the fact that many fans consider themselves to be related to the players.
