"It would be a huge win," Waldrum told reporters on Sunday, a day ahead of Nigeria's last-16 match with the Lionesses.
Nigeria are playing in their ninth World Cup, their top finish being a quarter-final appearance in 1999.
"I have watched, just like you all have, this World Cup unfold and seen some of the story lines that are out there, with teams that are successful," Waldrum, an American, said.
Nigerian striker Desire Oparanozie could make her first World Cup appearance on Monday after picking up an injury in training.
Waldrum said Oparanozie's status is undetermined, but "the good thing is she's now available."
