A penalty shootout involves a best of 5, with 5 different players (who finished the match) from each team taking shots, alternating. If both teams score the same number of goals, it goes to a sudden death, where the team that scores more goals than the opposing team within the same number of shots wins.
What if the number of eligible players is different between the teams? Wouldn't a shooter be unmatched with a shooter from the opposing team?
