Netherlands coach Louis van Gaal said there was no danger of taking quarter-final opponents Costa Rica lightly.
But he indicated that the Netherlands were already considering a place in the final as they aim for their first World Cup title.
"No, no, no. I don't think there's any question of underestimating Costa Rica," Van Gaal told reporters.
"I would say that the players consider this to be the most important stage and they are going for their objective. And the objective is not something we want to underestimate.
"Our goal has always been to win world championships," added the coach. "We're not a fantastic team but we're a team that's difficult to beat... and I hope we can keep that up, up to and including the final."
