Considering that Brazil is especially invincible in important competition, I think this is a pretty good reason ...
And Russia, we have beaten them with great fight and with even more luck! If we wanna beat them again we must become strong - twice times more than in December and for Brazil - 4 times. Because Brazil, the only team who REALLY can beat Brazil is neither Bulgaria, neither Russia and Poland - this is France! The only team who is playing like Brazil in defence.
