4. Closing out the period before half time

Against Cameroon, the Socceroos conceded moments after the fourth official signalled one minute of injury time prior to the break.

In the defeat to Germany, Australia gave away a penalty in the 44th minute, which Julian Draxler had no difficulties converting.

And when the national team played Saudi Arabia at home prior to the Confederations Cup, the visitors found the net with seconds left in first half.

Can the Aussie defence hold firm?

Against Germany and Cameroon, the ultimate outcome might have been different had the opposition not scored at such a vital time.

If Australia is going to beat Chile by two goals, they simply cannot afford to concede another goal on the half time whistle.

5. Postecoglou’s record

There is no doubt that the Australian manager’s time with the national team has been successful. Lest we forget that the Socceroos won the 2015 Asian Cup, perhaps the side’s biggest ever triumph.

Yet at FIFA tournaments – the 2014 World Cup and now in Russia – Postecoglou has struggled.

Admittedly neither group was favourable – Spain, Chile and Holland in Brazil and now Germany, Cameroon and Chile at the Confederations Cup.

What will be Postecoglou's legacy from the Confeds Cup?

But a manager’s job is to get results, and Australia has earned just a solitary point in these five games.

Unless Australia beat Chile, Postecoglou’s disappointing run in FIFA competitions will continue.

Given the Socceroos’ qualification for the 2018 World Cup is far from assured, that record could become an unglamorous part of his legacy.
