Brazilian fans are pathetic. When your teams are winning you act as if it's your personal success but as soon as things start going badly and there are conflicts you shit on everyone involved. I feel sorry for Brazilian players having to deal with such a cancerous fanbase.
Btw, I obviously don't think all Brazilian fans are like this, it's just the general impression I get. A lot of you are actually reasonable people, which is the case in every fanbase. Sadly, those ones make you all look bad.
