Changes are coming to the Matildas for their do-or-die clash with Norway but coach Ante Milicic is in two minds as to how to line Australia up.

But one thing is very clear to the coach at least as the Matildas bid to become the first Australian side of any stripe to win three games at a World Cup from 5am AEST on Sunday.

They're ready.

"We're all up for the challenge," Milicic said.

"We'll go and focus on the game tomorrow night to do a job, put on the best performance ... work hard and believe in ourselves.

"The girls are in a really good place."

A final call on the eleven to take on Norway will come just hours before the match.

For the first time in France, Milicic enjoyed the company of all 23 players for a training session in Nice, giving him plenty to think about.

One question to ponder is whether Clare Polkinghorne can resume in central defence after missing two games with a hamstring issue.

That would shift Steph Catley to left-back and free up Elise Kellond-Knight to play in her preferred midfield role.

"I'd like to see her play there too," Milicic said of Kellond-Knight.

"She's a very intelligent footballer, she's played a lot of football at left-back, she's professional.

"Whether we play her tomorrow as a six or as a full-back I'm sure she'll do a very good job for us.

"We go with some kind of stability into our line-up tomorrow so that's what we're looking at first and foremost."

With Tameka Yallop fit again, it seems certain she'll play alongside Chloe Logarzo in the middle.

The second big question comes up front, where Sam Kerr is likely to resume working with Caitlin Foord and Hayley Raso from kickoff after the pair were only substitutes against Jamaica.

"With the three games in ten days and we have one less (day) turnaround than Norway has for this encounter, it's very important to get some fresh legs into the line-up," he said.

In the opposition camp, key striker Caroline Graham Hansen trained with Norway on Friday, meaning the 24-year-old should play despite hobbling on crutches out of their match, a victory over South Korea.

Irrespective of her availability, Milicic is eager to continue his attack-first game plan, hopeful it will send the Matildas to the World Cup quarter finals for a fourth-straight tournament.

"She's (Hansen) a quality player. There's no doubt about that. We've prepared as if she is playing," Milicic said.

"They have a couple of world class individuals (but) we don't change our playing style or our principles based on a couple of world class players.

"I look at these group of players and they're very strong technically and they want to be in possession of the football. They want to attack and we've got a lot of quality going forward.

"I want to be proactive. I want touches on the ball. I want to create goal scoring opportunities.

"We see the girls playing with a smile on their faces and they're enjoying that, and that's what we're gonna continue to do."
