Brazil is a victim of their own international success
They lose their best players to europe before they even turn teenagers
While those young players may be identified as technically good. I believe that the true samba style football comes from being inculcated into the brazilian culture, it has its own personality.
From what i've seen of the modern team, they don't look very fluid nowadays. Solid yes cause those players come from the best european clubs but you can see the style of play is very different, almost european.
They may be better equipped to counter the Germans, Italians and the Spanish etc. but they will struggle a bit against south american opposition.
