Kaka scored on his Brazil comeback after a two-year absence and Oscar notched a brace as the 2014 World Cup hosts demolished Iraq 6-0 in a one-sided friendly in Sweden on Thursday.
Chelsea midfielder Oscar set the South Americans on their way to an easy win in Malmo with two goals in a five-minute spell midway through the first half against opponents who are coached by former Brazil captain Zico.
Real Madrid's Kaka, who last played for his country at the 2010 World Cup, added the third early in the second half before Hulk, Neymar and Lucas shared three more goals as Brazil's incisive passing sliced through the Iraq defence.
Iraq goalkeeper Noor Sabri prevented Brazil from inflicting further embarrassment with an inspired performance.
Iraq, unable to play at home for security reasons, face Australia in a World Cup qualifier in neutral Doha on Tuesday and Zico was unhappy at the timing and venue of the Brazil match.
"We left Qatar where it was 35 Celsius, travelled for 10 hours to a place where it's five Celsius and we have to go back again afterwards," he told Brazilian media before the match. "It wasn't the right moment."
