At just 18-years-old, it's hard to believe that prodigal Matildas defender Karly Roestbakken is still nearly two years OLDER than the youngest player in Australia's squad.
But that doesn't mean attending the World Cup as a squad member of a nation ranked sixth in the world is any less special.
“It has always been my goal to play for the Matildas and to get the call up, I wasn’t expecting it this soon," the humble Matilda said.
Roestbakken was an injury replacement for former Matildas stalwart Laura Alleway, who suffered through much of the W-League season due to injury and mixed form, eventually succumbing to a foot complaint.
"To get the call up to come to a World Cup is just an unreal feeling and it couldn’t have happened at a better time, so I am so honoured and so grateful to be standing here today," Roestbakken continued.
“I am absolutely gutted for Laura (Alleway), she is an amazing player and she does deserve to be here. (But) these things happen in football and it is unfortunate, and I wish her all the best in her recovery.
“All the girls and the staff have been excellent. Coming in and transitioning from the Young Matildas to the full women’s team, the girls have been great and really supportive, and so have the staff.”
Despite being named in Milicic's squad, Roestbakken is yet to make her Matildas debut, which could lead to a very memorable match against Brazil if Milicic decides to shake up the team following the disappointing 2-1 loss to Italy.
But while she's a novice at Matildas level, the Future Matildas breakout star has already made 10 appearances for the U20 national team.
“I am definitely learning a lot and I am getting more experience within international football for women, and learning what it takes to be a professional athlete," she said.
"I'm picking up a lot of things and learning to be a better footballer and learning more things on the field which is really great.
“Coming off W-League and then moving to Sydney with the Future Matildas has helped me immensely.
"Because we train with a few of the Matildas, the ones that are still in Australia, it is really helpful being there, being able to train with them and doing what they do.
"The transition is a bit easier coming from that into the Matildas squad, so it has helped me immensely.”
The Matildas now face a hectic few days as they seek to avoid a shock group stage defeat, but Roestbakken has reason to be confident.
Australia have a history of losing their opening matches at World Cups - losing the first encounter in the majority of their appearances, in fact - yet have made the quarter-final at the last three attempts regardless.
“Yesterday morning we flew from Valenciennes to Montpellier," Roestbakken added.
"The weather is a lot different so I think we have just got to adjust to that. It is a lot warmer here, but we are looking forward to the game on Thursday.
“The girls are obviously gutted for the first loss but as it is the first game and you have got to deal with these things in football.
"But I definitely think it will fire them up and they will be ready to go on Thursday.”
