the second leg, the final score goes as follows: Second leg, after 90 minutes: Team A (Away) 0–1 Team B (Home). Second leg, after extra time: Team A (Away) 0–1 Team B (Home). In this example, the aggregate score is 1–1, but as neither team scored an away goal, the match will progress to the next tie-breaker, extra time. Since no further goals are scored there, the match will progress to a penalty shootout. Example F First leg: Team A (Home) 0–1 Team B (Away). Second leg: Team A (Away) 2–1 Team B (Home). In this example, the aggregate score is 2–2. However, because Team A has scored more away goals than Team B, Team A will progress to the next stage of the competition. Rationale Originally, the away goal rule was introduced in football as an expedited way of doing away with playoffs or tie breakers on neutral grounds to resolve a logistical, physical and calendar problem when two teams were so closely matched the final score over the two legs remained in absolute parity, which could remain even after a third game tie breaker. The away goals rule is intended to encourage the away team to be more aggressive. In football, at least, it can lead to a nervous first leg: the home team is unwilling to commit large numbers of players to attack to avoid conceding an away goal, whilst the away team attempts to snatch an away goal to aid them in the second leg. Such tactics arguably make the second leg more exciting, after a low-scoring first leg leaves both sides with a chance to win. There are sometimes debates over whether the away goals rule gives an unfair advantage to the team playing away first — with the other team squandering their home advantage in the first leg due to away goal fears — and this may be a factor in its somewhat patchy adoption for competitions. The rule can also make the game more exciting as normally one goal can only make the difference between losing and drawing, or between drawing and winning, but with the away goals rule, one goal can make the difference between losing and winning. There is also the issue that if extra time is played in the second leg, the away team gets an extra 30 minutes to take advantage of the away goals rule. This can be
