But it hasn't always been that way as the Eagles prepare for a taxing 24-hour trip to the World Futsal Championships in Orlando, Florida on Friday morning.

Day and Hargreaves are the remaining originals from an Eagles team who were outclassed 21-1 at the national titles in New Zealand in their inaugural match back in 2008.

At the time, Day was a fresh-faced 14-year-old while Hargreaves was just 15.

They are now integral members of the side who have turned it around and not dropped one match in the last two and a half years.

After winning the open women's title at the Australian National Futsal Championships this year and last year, the Eagles received an invitation to play in the USA.

It's the first time an Australian women's team has been invited and it's a full-blown affair involving 120 teams from around the world.

When asked what changed and why the team are now so successful, Day admitted it was a change relating to their dedication and commitment.

"We all stayed together and then eventually consistency came because we trained so hard," she said.

"We gradually got better and went from being flogged 20-0 to 10-0 and then we started to win games."

A loss in the Escape Cup against Victoria in the grand final three years ago was pinpointed as the turning point.

"It still hurts us," she said.

The close-knit nature of the group allows it to double as a family which also contributed to their success.

"We won't walk into a stadium without one of our team members; we're all attached at the hip," Day said.

"If one person drops we pick them up."

Hargreaves has lined up in goals for most of the competitions the Eagles have competed in since 2008 and she will have a significant role to play in the United States.

"We want close matches, we don't want to go over there and win by heaps or lose by heaps," she said.

"There are a few of us that have been around for some time and we've stuck together through those losses and now we've gotten better and better.

"That makes us a stronger team compared to most others who change their girls ... we tend to keep the same seven."

The tag of world champions is one of the few items left for the team to claim in the last four years where they have been arguably the most consistent futsal team around.

"It feels like a reward for all our hard work and those 20-0 defeats are all worthwhile," Day said.

"We don't like to lose."
