According to polls conducted on social networks and various media, the national teams of the 1980s and before the 1990s enjoyed undeniable popularity among the people, but the main issue that needs to be investigated is whether this decline in the popularity of national players is solely due to technical issues. Or is it due to the players' lack of participation in social events and their indifference to what is happening in society?
