Host nation Brazil are still searching for their opening win of the Rio 2016 men’s football competition after an embarrassing 0-0 draw against Iraq.
Led by Barcelona forward Neymar, Brazil could not find a way past their stubborn Group A rivals in Brasilia.
It is their second goalless draw of the tournament after another blank against South Africa on Thursday.
Elsewhere, Germany drew 3-3 with South Korea thanks to an injury-time free-kick from Arsenal’s Serge Gnabry.
Brazil frustrated in Olympic bid
Brazil may have won the World Cup on a record five occasions, but the football-mad nation is desperate to finally claim the one prize that has so far eluded them – Olympic gold.
However, they were jeered by an impatient home crowd of more than 60,000 after failing to beat Iraq.
Brazil had 20 shots at goal, but only managed six on target as the Asian side held on.
“We need to apologise to the fans, to the people,” said Brazil coach Rogerio Micale. “As the time passes and we can’t score, the anxiety increases, and in this situation it’s easier to make mistakes.”
Iraq coach Abdulghani Alghazali said: “It’s a historic day for Iraq to be able to draw against Brazil at its home. It’s a great achievement for Iraqi football.”
Denmark top the group with four points after Robert Skov’s 69th-minute winner gave them a 1-0 victory over South Africa.
