Henry Birtles' "Advantage" proposal is for the shoot-out to be held before extra-time, and only acting as a tiebreak if the game remains a draw after the full 120 minutes. Proponents of this idea state that it would lead to a more offensive extra-time as one of the teams would know they have to score and there would never be a match in which both teams are simply waiting for penalties. Another advantage is that players who have missed would have a chance to redeem themselves in extra-time. The obvious flaw is that the team that wins the penalty shoot-out would be inclined to play defensively in extra time in the knowledge that a draw would put them through. However, this flaw is not so clear because a single goal makes the difference between winning and losing, as opposed to a team that defends a single-goal lead more comfortably because a conceded goal is the difference between winning and drawing.
