"When I was at school, it was one of the places to go to for women's football," said Yallop, a 12-year veteran of the Ferns who made her debut as a seventh former in 2004. "There was Hayley [Bowden], Maia Jackman and Kristy Hill, while Amber [Hearn] was a couple of years older than me."
The fourth member of the quartet is midfielder Hassett, who has played professionally in England and Germany since her school days.
"I've seen a couple of teachers today. It all feels very familiar," said Hassett. "Someone like Kirsty [Yallop] inspired me a lot. When you saw someone at your school playing for New Zealand you realised what was possible."
The hundreds of pupils at today's announcement created a special energy, but there were few surprises in Readings' squad. It's easily the most experienced team in Ferns' history, with five players boasting more than 100 caps (Abby Erceg, Katie Duncan, Hearn, Ria Percival and Ali Riley) and another six who have more than 70 appearances. There are seven players who played in both Beijing and London, and only two members of the squad have yet to experience an Olympics.
"It makes such a difference when you have been there, done that," said Yallop. "It means you are more prepared for everything that might happen."
And just like they did before the 2015 Women's World Cup, Readings and his team aren't holding back from making bold pronouncements.
"It's the strongest team we have ever assembled," said Readings. "We are going there to win a gold medal. Whether people think that it is realistic or not, we are not really bothered. We have set gold medal standards. Everything we do is [around aiming] to be the best in the world. We will take it one game at a time and once you get out of your group you are a game away from a medal. We will strive for the top spot and do the best we can."
