That, though, does not preclude him taking soundings from those in leadership roles across the sporting domain of the Greek immigrants’ adopted Australia, an environment central to moulding his methods.

“Growing up in Australia, the disadvantage of loving football is that it isn’t the number one sport, but the advantage of loving sport is that you are surrounded by it,” said Postecoglou, who has a successful spell with the Australian national football side on his glossy CV to help the sport start to emerge from the lengthy shadows cast by cricket and rugby. “So, growing up I was lucky enough to be exposed to multitudes of team and individual sports on my doorstep, and I’ve kind of used those networks throughout my whole career, whether that was as a player or now that I’m coaching.
