Ok, examples? And is it exclusive to Brazilians? I usually dont like Andy's bashing of italian players, but how is it any different with them? Or better yet, they are more true to your point for sure then Brazilians, while in general not offering as much quality.
And its really simple, generalizing is bad and counterproductive, its much simpler and senseful to talk about the player himself, instead of badmouth a whole footie nation (when they are the most successful footie nation there is). You cant give up on and dismiss all brazilian players because of a doofus like Amauri or such. Would you say no to Maicon or Juan just because they are brazilian? Many many examples to mention, but thats for example what you are doing when you dismiss all brazilians like that.
