Hope I'm right about this, I'd appreciate any corrections. USA wins = Group winner USA draw = Group runner-up USA loss + Ghana/Portugal draw = Group runner-up If USA loses and Ghana win ------------------ Any result other than one goal win for Ghana and one goal loss for USA = Ghana advances on goal differencial. If Ghana wins by one and USA loses by one, they tie in goal differencial: Ghana doesn't outscore USA on Thursday = USA advances on total goals scored Ghana outscores USA by 1 goal = They tie on goals scored and USA advances via head-to-head result Ghana outscores USA by 2 goals or more on Thursday = Ghana advances on total goals scored. If USA loses and Portugal wins ------------------ If Portugal margin of victory + USA margin of defeat is >5 (e.g. 3-0 Portugal win and 0-3 USA loss) = Portugal advances on goal differencial If Portugal margin of victory + USA margin of defeat is <5 = USA advances If Portugal margin of victory + USA margin of defeat equals 5 they tie in goal differencial: Portugal outscores USA by 3 goals on Thursday = Portugal advances on total goals scored. Portugal outscores USA by 2 goals = Drawing of lots (tied in points, goal differencial, goals scored, and head-to-head) Portugal outscores USA by less than 2 goals = USA advances
