Australia's Socceroos, led by new coach Tony Popovic, are preparing for a crucial World Cup qualifier against Japan after a rejuvenating 3-1 victory over China. Popovic's tactical shift to a back three has shown promise, despite some initial miscommunications during the match. Players, including defender Aziz Behich, believe in the potential for improvement and have adopted a confident mindset, aiming for a win rather than settling for a draw in Japan. The Socceroos face a formidable challenge as Japan leads Group C and has yet to concede a goal in their qualifying campaign. The match is particularly significant for Popovic, who has a history with Japan's coach Hajime Moriyasu, adding an intriguing personal element to the clash. With only the top two teams guaranteed World Cup berths, this match is pivotal for Australia's aspirations in the qualifiers.
