Chile have suffered an extraordinarily bad run against the Brazilians in the last five years, losing seven matches in a row and shipping 26 goals in the process.
The have also lost their only two World Cup meetings against Brazil - 4-2 in the semi-finals at the 1962 World Cup, which they hosted, and 4-1 in the second round at France in 1998.
"The things that Brazil have done in the past exempts them from any sort of comment," said the eccentric and enigmatic Argentine.
"They are always a team to be feared and this latest version preserves all the footballing attributes of the country and, in addition, adds speed and ruthlessness."
Chile's losing sequence began with a 1-0 defeat in a Copa America group match in 2004 followed by a 5-0 loss in a World Cup qualifier the following year.
A fast, attacking but somewhat lightweight team, Chile tend to be easy prey for the physically powerful Brazilians and, in their enthusiasm to pour forward, leave gaps at the back which are usually ruthlessly exploited by Brazil's forwards.
Felipe Melo is very doubtful for Brazil but that is unlikely to be a problem for Dunga's team, whose squad is overflowing with midfield spoilers.
Former World Player of the Year Kaka will also be back after suspension and Robinho, rested for Friday's match with Portugal, should play, adding much-needed creativity to a generally lacklustre Brazilian team.
Brazil regularly complain that opponents shut up shop against them but Chile's former Argentina boss Bielsa is a bold coach and it is in his nature to send his teams onto the attack, whoever they are facing.
