Brazil coach Dunga said his team had rescued the self-esteem of their supporters by winning the Copa America. He also warned that Ronaldinho and Kaka, who asked to be rested from the tournament, would have to fight to get their places back in the team.Dunga took over with Brazil at a low ebb after their lacklustre performances at the World Cup last year. After only 11 months in charge, he won his first title on Sunday when his team beat arch-rivals and favourites Argentina 3-0 in the Copa America final. “We came here to rescue the self-esteem of the Brazilian supporter, the worker leaves home early in the morning and comes back late at night and whose only satisfaction is when Brazil wins,” said Dunga.He then paid tribute to his players, who he said had come from adversity to triumph. “They are winners, they come from families who financially are not so well off, nobody has given them anything, they’ve worked hard for this and so they deserve it,” he said.
