The only question at right-back is whether USWNT coach Pia Sundhagen throws caution to the wind from the start and fields a three-woman defence.
Desperately needing a goal to stay in the tournament, Sundhagen withdrew LePeilbet for forward Sydney LeRoux late against Canada, shifting Rampone over to cover the wing in a daring 3-4-3 formation.
It's a potential option against Japan to try to break down their staunch defence early; but more likely, particularly given the physical toll of USA's semifinal, Sundhagen will stick to a 4-4-2 with LePeilbet on the right.
