The Over 35 Masters football team must beat South Africa in their final group game on Thursday to reach the last four.
Paul Linger scored a late winner as they beat USA 1-0 in their opener. This was followed by a goalless draw against Mexico.
Manager Darryl Lee said: “If we beat South Africa we’re out of the group but ideally we want to avoid Argentina in the semis. I have been surprised how defence teams have been against us. Mexico packed 10 men behind the ball.”
Victory against SA would set up a clash against Israel, Brasil or Argentina.
