Krul prowled around his area in an attempt to psyche out the Costa Rica penalty takers, pointing to his eye to let them know he'd done his homework.
Maybe he had, maybe he hadn't. But his efforts to unnerve his opponents worked.
Krul first dived low to his left to save from Bryan Ruiz and when Dirk Kuyt drilled the Netherlands' fourth spot-kick home, Michael Umana knew he had to score to keep his side in the competition.
Sadly for Umana and the tiny Central American nation of five million souls, he couldn't, as Krul again went low to his left to push the spot-kick round the post and end the dream of these most valiant of underdogs.
"We cannot blame anyone because to be there at that time is not easy," said Navas, who was named man of the match for the third time at Brazil 2014.
"Our rivals did their job in the penalty shootout and we didn't."
Pinto admitted his team had been "lucky throughout the game" but expressed his great pride.
"We are not a world football power but we have done very important things here," the Colombian said.
"We go home proud of what we have done and I want to express my gratitude to the Brazilian people."
