Socceroos coach Tony Popovic has dropped goalscorers Nestory Irankunda and Connor Metcalfe to the bench for Australia's blockbuster clash with the United States.
Veteran Mathew Leckie, playing for the first time at his fourth World Cup, and Nishan Velupillay are the two inclusions in attack for the game that could determine who finishes top of group D.
Irankunda, who was electric in the 2-0 win over Turkey, including scoring a brilliant opener, and Metcalfe, who delivered a wonderful second-half goal, loom as impact substitutes.
