Australia’s backline is comfortably the most inexperienced part of the squad and with Ryan McGowan unlikely, Postecoglou could potentially use skipper Mile Jedinak as a makeshift defender.

In addition, the goalkeeping situation isn’t set in stone, with Mitchell Langerak’s good form with German 2.Bundesliga champions VfB Stuttgart boosting his case to displace Mat Ryan.

Another factor to consider is that English Championship players such as Jackson Irvine, Bailey Wright and Massimo Luongo haven’t played competitively for a month, along with domestic-based players such as Tim Cahill and James Troisi, plus Dylan McGowan and Jamie Maclaren who’ve recently signed new deals with European clubs.

Postecoglou said the varying schedules had been well managed internally and said it wouldn’t affect selection.

“The pleasing thing for me is juggling all their schedules, some played until last weekend, others haven’t played for a month, maybe a bit longer,” he said. “Looking at them from a physical and mental stand-point, they’re all raring to go and putting their hand up, which is the most important thing.”

Postecoglou hinted he’d likely give opportunities to Bailey Wright and Milos Degenek in defence.

“We’ve got some guys at the back, Bailey Wright and Milos, guys in their early 20s who are starting to grow and playing in strong leagues now,” Postecoglou added.

“(With Ryan McGowan) He played on the weekend, so he is absolutely match fit… but it’s unfortunate he obviously had some flight challenges.

“That’s not unique. We’ve had other times where players have in a couple of days before the game and played.”
