The Tokyo Games are the Netherlands' first Olympics and on the eve of the tournament, they received a rousing team talk from former men's team manager Louis van Gaal.
Netherlands coach Sarina Wiegman is stepping down after the Olympics to lead England in the next World Cup cycle.
Wiegman will be replaced by Portland Thorns coach Mark Parsons at the conclusion of the National Women's Soccer League season.
This is also Zambia's first appearance in the Olympics. Known as the Copper Queens, Zambia had played just once this year, a friendly with South Africa. The team's scheduled tune-up match with Britain ahead of Tokyo was called off because of COVID-19 restrictions.
