Well you've been following this one closer than me guys, what does this stem from..? If I were to guess I would say that economically, Brazil is still a boom-land, but the money is not getting down to the have-nots [as usual], so is this politically aggravated or just football going potty in Brazil..?
Well it's a particularly crucial game. Vasco are relegated if they lose and Atletico I think can qualify for the Copa Libertadores. I don't think it's indicative of a rise in football violence or anything. For now I'd just assume it's an isolated incident in a particularly tense game.
