All four teams can win Group C ahead of the final round of fixtures at the Copa America on Sunday.
Brazil take on Venezuela in Santiago and victory for either will guarantee them a place in the last eight, with all four teams on three points with a goal difference of zero.
Brazil
Dunga's side needed a last-minute winner to beat Peru in their opening game and then fell to Colombia in a heated affair on Wednesday night.
Superstar forward Neymar was sent off in injury time for kicking the ball at Pablo Armero and seemingly directing a headbutt at another Cafeteros player.
That means that he will be missing here and Brazil need a win to ensure they have a place in the quarter-finals. They will know exactly what they need as this match is the last of the group stages and a draw should also be enough for a top-three finish.
The defeat to Colombia ended a winning streak of 11 games since they exited their own World Cup at the semi-final stage a year ago.
The Selecao have won four of the last six Copas, going out at the quarter-final stage four years ago in Argentina.
In total, they have won the competition eight times, which is seven fewer titles than Uruguay, winners of the last tournament.

Venezuela
The lowest-ranked team of the group, Venezuela started with a stunning victory over Colombia in Rancague last Sunday, but then lost out to Peru last night.
It was a great opportunity for La Vinotinto to secure their spot in the knockout round, but Fernando Amorebieta was sent off as they went down 1-0.
A surprise win over Brazil would guarantee Noel Sanvicente's men a place in the knockouts, while a draw should be enough for a top-three spot, unless Colombia and Peru play out a higher-scoring draw in the earlier match.
After going out in the first round in 12 straight Copas from 1975 to 2004, Venezuela have improved in the last two tournaments.
In 2007 they went out at the quarter-final stage, before four years ago stunning Chile in the last eight and only missing out on the final with a penalty-shootout defeat to Paraguay.

Neymar is definitely out, so Liverpool's Philippe Coutinho might start in his place after coming on at half time against the Colombians.
Elsewhere, Douglas Costa will be hoping to start after scoring the late winner against Peru in the opening match.
Like Brazil, Venezuela have a player suspended after Amorebieta's red card against Peru.
Gabriel Cichero should come in for the Fulham man in what could be the only Vinotinto change.
Brazil possible starting lineup:
Jefferson, Alves, Miranda, Silva, Luis, Fernandinho, Elias, Willian, Costa, Coutinho, Firmino
Venezuela possible starting lineup:
Baroja, Cichero, Vizcarrondo, Rosales, Tunez, Arango, Guerra, Rincon, Seijas, Vargas, Rondon
Head To Head
The last meeting between these two was four years ago at the last Copa when they were also drawn in the same group. It finished goalless and that was the second straight 0-0 draw between the Selecao and Vinotinto.
Before that, Brazil had convincingly won six of the last seven meetings, with the only blip a 2-0 friendly defeat in a 2008 friendly held in the United States.
We say: Brazil 2-0 Venezuela
They are without their superstar forward, but Brazil will still start as favourites against the world number 72. Venezuela did fantastically to beat Colombia, but missed their chance to go top by losing to Peru and this might just be a step too far.
