Via John Duerden in go.com: Australia hosts Saudi Arabia in a crucial World Cup qualifier at Melbourne on Thursday while Japan and South Korea can take a big step towards North America in 2026 when the third round of Asian qualifying reaches the halfway stage. With only the top two teams from each of the three groups of six progressing automatically to the expanded 48-team tournament, Australia and Saudi Arabia both have only five points from four Group C games, five behind leaders Japan. The sputtering form of the two teams has already resulted in coaching changes since the third round began. Graham Arnold stepped down as Socceroos head coach in September and was replaced by Tony Popovic while Saudi Arabia fired Roberto Mancini in October after a 0-0 draw with Bahrain in Jeddah.
