4. Is Leckie being muted by the new system?

Recent Hertha Berlin signing Leckie was once hailed as part of the cure for Australia’s creative woes going forward.

But the Bulleen Lions youth product has looked subdued in attack during the Socceroos’ Confederations Cup campaign.

Postecoglou’s 3-2-4-1 requires the 26-year-old to play an important defensive role on the flank, and the current frailties in the Australia defence have only added to his duties at the back.

Fatigued after a 30-game season in the Bundesliga with Ingolstadt, is too much being expected of Leckie?

5. All to play for in Moscow

The late game in Kazan saw another 1-1 score line, Chile and Germany playing out an entertaining draw.

Thursday’s results mean that, to qualify for the semi-finals of the Confederations Cup, Australia must beat Chile by two goals or more and hope that Cameroon do not secure a win over Germany.

While Cameroon are unlikely to beat Germany, the Socceroos’ performances in recent months provide little hope that they can comprehensively defeat the impressive South American champions.

But if the history of Australian sport has taught us one thing, it is to never say never.
