Brazil's Kaka, sent off after two yellow cards in his last World Cup game, was booked again in the 3-0 win over Chile on Monday, prompting coach Dunga to complain that referees were booking the wrong players.

After receiving only the third red card of his career against Cote d'Ivoire the usually placid Kaka, considered a role model in Brazil, was booked for a trip on Arturo Vidal in the first half of Monday's second-round game.

"It's a problem, I don't want Kaka to get suspended again," Dunga said.
