"Colombia have been working hard for eight months and they won't change because of one match.</p> <p style="text-align: justify">"Any team coming off a poor result has pressure because everyone watching believes that if a game didn't go well you have to change everything, and if it went well, everything's fine.</p> <p style="text-align: justify">"The person in charge has to have the calmness, the balance to know what things need to be done, what measures need to be taken.</p> <p style="text-align: justify">"Colombia had their opportunities. They allowed a goal very early and that makes things harder."</p> <p style="text-align: justify">Dunga is expecting a testing battle with Colombia, one of the revelations of last year's World Cup, when they were eliminated 2-1 by Brazil in the quarter-finals.</p> <p style="text-align: justify">"The rivalry's been large since the World Cup," Dunga said. "At the Copa America it will be a difficult match, like all of them have been at this Copa America."</p> <p style="text-align: justify">Brazil, 2-1 winners over Peru in their opening game on Sunday, will qualify for the quarter-finals if they win on Wednesday while Colombia will be all but eliminated.</p>
