A much-changed Selecao cruised to a 2-0 win in Sao Paulo on Sunday, leaving the boss a number of quandaries ahead of this month's Copa America.
Brazil coach Dunga admitted he has a real selection headache at this month's Copa America after Philippe Coutinho and Diego Tardelli starred in Brazil's 2-0 victory over Mexico on Sunday.
The duo hit first-half goals as Brazil grabbed its ninth win on the bounce - the first at home since last year's World Cup.
Dunga made a number of changes as regular starters Oscar and Luiz Gustavo have withdrawn from his squad through injury, while captain Neymar was unavailable for Sunday's match after leading Barcelona to the Champions League title on Saturday.
