Australia lifted the inaugural Cup of Nations on Wednesday night in Melbourne after going through the tournament undefeated and conceding just a single goal. 

However, the 3-0 scoreline against Argentina at AAMI Park didn't reflect the closeness of the match between the world no.6 and no.36 nations. 

Argentina challenged the Matildas throughout the game and if they were a team who had more international experience under their belt, it could have been a different result.

Milicic made a host of changes to the squad which beat the Korea Republic 4-1 in Brisbane while central defender Laura Alleway was forced from the field with an ankle injury early on, leaving the Matildas with a make-shift defence.

"I thought we were sluggish from the start but very slow in our build-ups, slow in shifting the ball and moving the opposition," Milicic said.

"We weren't decisive in our passing and our decisions, probably need to work on our positioning higher up the pitch.

"I think at the same time we were a little bit naive as well, we played a game I think they were after, so disappointed in a couple of areas but overall I'm pleased how the last 10 days have gone."

It's been rollercoaster three months for the Matildas and those involved with the squad since the abrupt sacking of Alen Stajcic in January, just five months out from their opening World Cup match. 

Milicic, who was only appointed as the interim head coach on February 18, took his first training session five days before the Cup of Nations begun with the round-robin tournament used to help him and the Matildas begin their World Cup preparations. 

"We just want to provide an environment where these girls have the best possible chance to go as deep in that World Cup tournament as possible," he said.

"This is what this tournament was about, it wasn't about getting results, yes they are important and we want to win every game we go into but looking at the overall big picture this tournament was to prepare ourselves for the World Cup and that's what we're firmly focussed on."

So far the former right-hand man to Ange Postecoglou has implemented small changes to the squad's style of play including an emphasis on keeping possession and playing it out from the back at all costs. 

This style works wonders against teams who are willing to give the Matildas space but when teams press them as Argentina did, then passing has to be 100 per cent accurate or the ball will be lost in important areas. 

It's was always known that the 44-year-old wouldn't have a lot of time to prepare ahead of the World Cup. 

The Matildas have just 93 days until their first group match against Italy in Valenciennes with just one more friendly on the cards at the moment, that being against the USA next month.

There are high expectations for Australia heading into France. The Matildas are currently ranked in the top 10 in the world and have reached the quarter-finals of the last three World Cups.

However, Milicic as assured that the side will be ready come June 9.

"Make no mistake by the time the World Cup starts this will be a well-prepared side," Milicic said.
