Brazil and Argentina endured more frustration in the World Cup qualifiers yesterday with draws against bottom sides Bolivia and Peru respectively.
Brazil were jeered by their own fans in a goalless stalemate at home to bottom-of-the-table Bolivia, who played the last 35 minutes with 10 men. Argentina drew their fourth successive qualifier when Peru scored with the last kick of the game in Lima to snatch a 1-1 draw.
The two arch-rivals stayed level on 13 points from eight games where they were joined by Chile, who returned from Sunday's 3-0 home defeat by Brazil to thrash Colombia 4-0 in Santiago.
Paraguay, 2-0 winners over Venezuela on Tuesday, lead the 10-team group with 17 points.
The top four teams qualify directly for South Africa and the fifth plays off against a team from the CONCACAF region.
Brazil's dismal performance in Rio de Janeiro put the heat back on coach Dunga, who had enjoyed some respite with the win in Chile.
As well as poor results and failure to win gold at the Olympic Games, Brazilian fans resent his safety-first tactics.
Yesterday's game in Rio de Janeiro, where the public are notoriously fickle, was seen as a gauge of his team's popularity. But with the cheapest tickets costing the equivalent of $60, the Joao Havelange stadium was half full and the reception lukewarm.
Frustrated with another lacklustre display, the crowd quickly became impatient and even cheered Bolivia when they went forward.
The visitors, who conceded 16 goals in losing their previous four away games, had Ignacio Garcia sent off in the 54th minute for a foot-up challenge on Robinho, although replays showed no real contact was made.
"When we don't play well, it's normal," said Dunga, shrugging off the crowd's reaction.
Ronaldinho, taken off in the 77th minute amid more whistles, added: "The Brazilian team always has the obligation to win."
Argentina are under less pressure but there is still concern at their talent-laden team's failure to perform consistently.
Esteban Cambiasso's 84th minute goal appeared to have given them a welcome break but lowly Peru snatched a deserved point when Johan Fano slid the ball home in the fourth minute of injury time following a 70-metre run by Juan Vargas.
Results: Brazil vs Bolivia 0-0; Peru vs Argentina 1-1; Chile vs Colombia 4-0; Uruguay vs Ecuador 0-0.
