Holger Osieck
Postecoglou was appointed head coach of the Australia national team on 23 October 2013 on a five-year contract, replacing German Holger Osieck. Postecoglou was tasked with regenerating the Australian national team, which was deemed to have been too reliant on members of their Golden Generation of 2006, subsequently leading to a stagnation of results that culminated in successive 6–0 defeats to Brazil and France. In his first game as Australia's manager, a home friendly match against Costa Rica, Australia won 1–0, courtesy of a goal from Tim Cahill.
