Luis Fabiano and Kaka have both admitted their delight at seeing their arch-rivals Argentina get thrashed 6-1 by Bolivia yesterday.
The Brazilians beat Peru 3-0 to move above Argentina in qualifying and put themselves within striking distance of leaders Paraguay.
Speaking to Globoesporte after the match, Fabiano had double reason to celebrate after scoring twice and seeing the Albicelestes defeated.
"It always make us happy to see Argentine lose so badly," said the Sevilla striker.
AC Milan midfielder Kaka, who returned to the Brazilian line-up for the match with Peru, spoke not only about Argentina but also about the effects of altitude.
"Is everyone not saying that Argentina are so good?" he quipped.
"Now the whole world can see that altitude does make a difference. Argentina beat Venezuela and then they suffer this humiliation.
"Altitude is not an excuse though to justify this or that."
The play-maker went to say that to be in front of Argentina in any shape or form is "always good".
Perhaps predictably, Dunga was a lot less reserved about the subject when questioned about the Argentine defeat.
"Altitude does affect a lot, it was clear in the play of Argentina," he said.
Along with the coach, Gilberto Silva was also less controversial in his statements, saying that "we also have to play there [in La Paz] and playing at that height is difficult".
