Australia's Connor Metcalfe has warned his teammates to avoid reacting to Saudi Arabia's gamesmanship when the nations face off in Jeddah on Tuesday with automatic qualification for next year's World Cup finals on the line.

Australia coach Tony Popovic has warned his buoyant team they still "need to do a job" after propelling themselves to the cusp of a sixth successive World Cup."We need to do a job in Saudi," he told reporters.

Uzbekistan (world No. 57) only needs one win from its remaining games to join Iran at the World Cup. United Arab Emirates (65) are likely to finish third, while Qatar will reach the next round unless it loses its last two games and Kyrgyzstan wins both its fixtures.
