Tite's men have already booked their place at the finals and are nine points clear of second-place Colombia with four games to play.
Because of their significant goal-difference advantage, maintaining that nine-point lead by winning in Porto Alegre would almost certainly ensure that they head to Russia as the top team from their continent.

BETTING & MATCH ODDS
Brazil are 4/6 favourites to win, according to Oddschecker, with Ecuador priced at 12/1 and the draw available at 19/4.
Neymar is the 13/5 favourite to score first, with Gabriel Jesus priced at 3/1 and Enner Valencia the top choice for the visitors at 12/1.
Brazil have reached the home straight. Visits to Colombia and Bolivia still await the Selecao but they have qualified for the 2018 World Cup and may be untouchable at the top of the South American qualification table by the time they set out on those away trips.
Everything seems to be falling into place for Tite.
Neymar has secured the move to Paris Saint-Germain that will allow him to be the main man week in, week out, while Philippe Coutinho may be about to take a step up by joining Barcelona to replace him.
Casemiro is a favourite of the manager of the best team in the world and Gabriel Jesus looks as if he has been playing in the Premier League for years.
So many of the coach's key men appear set for big, momentum-building seasons and when they come together, they look a far more assured side than the one that so infamously imploded at the last World Cup.
There are few who will want to face them next summer.
