LOS CATALANES SUPREMA
Ghana is -1 in goal differential and the US is +1, so Ghana would have to win by 3 goals to upend the US.
To append this message, let's say Ghana wins and the US loses to Germany. Both teams would have 4 pts so Ghana would have to score 2 goals or more to pull out of the group. Had to think about the math for a sec to see what possible scenarios/permutations are out there.
