SANTOS, Brazil - Costa Rica are the biggest surprise in the 2014 World Cup, and they want to extend their dream by sticking to what has taken them to the quarter-finals.
"We don't have to change anything," keeper Keylor Navas said in Santos.
"We will give our lives in one of the most beautiful games of our lives. We want to win it, and we have shown we have what it takes."
Costa Rica will on Sunday play their first ever World Cup quarter-final against the Netherlands in Salvador.
"The most important match now is the one against the Netherlands. We have made history. Football is about moments, and we don't know if we will ever again have a chance like this one," said defender Giancarlo Gonzalez.
Gonzalez noted the "Ticos" have already got through a group with Italy, England and Uruguay with two wins and one draw, before beating Greece in a penalty shootout in the last 16 stage.
