Matt Jurman is mentally preparing for the real prospect he could make his Socceroos debut in Malaysia at the start of Australia's most important set of matches for more than a decade.
Matthew Spiranovic's loss was Jurman's gain for Australia's 2018 FIFA World Cup qualifying playoff series against Syria, earning a "dream" first call-up to the final 23-man squad after narrowly missing out from the extended 30 last camp.
The former Sydney FC centre-back has been reaping the benefits of his gamble to leave the A-League champions for the frantically paced K-League.
Jurman has fronted Socceroos camp in excellent physical shape and, crucially, with experience playing as part of a back three with his club Suwon Bluewings.
Bailey Wright's suspension for Thursday night's opening away leg in Malacca has thrust the quietly spoken 27-year-old well into the frame for a start that just two months ago would have been deemed unlikely.
"I'm here, so I've got to be in that mindset that Ange might pick me," Jurman said on Tuesday.
"I'm starting to really realise that this could happen on Thursday and, if it does, I'll be ready.
"I think it's been a blessing in disguise that my club actually plays with a back three. It's helped me to learn how to play in that system. If I'm picked to play, I'll have that experience behind me.
"It's a different system to what I've played before in Sydney with Arnie (coach Graham Arnold) but, once you get games under your belt, it makes it easier."
Jurman has been playing as a left-sided central defender in the Bluewings' back three, meaning he could slot in next to Trent Sainsbury and potentially Milos Degenek, should Postecoglou choose to deploy Mark Milligan in his favoured midfield position.
"He's a chance," Postecoglou said.
"His form has been good in Korea ... he's doing well for a club that's going well and that's usually a good sign that his form is stacking up. He plays in a back three and he'll come in.
"He's presented himself well, he's in good condition and had a good game on the weekend. He's certainly in line for an opportunity."
By Jurman's own reckoning, life has been pretty good in Korea.
Apart from his international breakthrough, Bluewings are fourth in the league and the Wollongong native has accrued a healthy local fan following.
"I've enjoyed it so far," he said. "It's been different and good to see how they do things, their culture. There have been some eye-openers at stages but the games are very intense.
"Ninety minutes finishes and you see about 10 players drop to the floor because they've given everything. Every game is like that.
"My fans are probably the best in the country. They seem to like what they've seen and I'm happy to be playing for them."
