Brazil coach Dunga has told David Luiz that he can have no complaints over his red card in Saturday's 1-1 draw with Argentina.
The Paris Saint-Germain defender was booked on 86 minutes for aiming an elbow at one of his opponents, before lunging into a studs-up challenge two minutes later as the Selecao finished the contest with 10 men.
"He deserved to be sent off," Dunga told reporters afterwards. "There's nothing to complain about."
Ezequiel Lavezzi had opened the scoring after 34 minutes in this morning's World Cup qualifier in Buenos Aires, but Lucas Lima levelled up in the second period.
