countered by the fact that in extra time, the home team has the advantage of playing the extra 30 minutes at home. In addition, usually, the home team had made a better campaign in the group stage, which would naturally give it some advantage over the away team. Anecdotal evidence suggests that most teams feel an away goal puts them in the driving seat, such as Liverpool being able to draw 1–1 at Arsenal in the 2007–08 UEFA Champions League quarterfinals; Liverpool did eliminate Arsenal to advance to the semi-finals. Liverpool won the second game 4–2, making the aggregate score for the tie Liverpool 5–3 Arsenal, therefore, the away goal scored by Liverpool in the first leg was not required. Many commentators have described the importance of a team being able to score an away goal, even when losing that leg of the tie, as it mathematically does give that team a chance to redeem itself on home soil by leveling the tie on aggregate while using the away goal as a tiebreaker. For example, in the 2007 UEFA Champions League round of 16, while Bayern Munich lost the first leg 3–2 at Real Madrid, Bayern later won 2–1 at home to level the tie on aggregate, but it was Bayern's away goals scored during their first leg loss that let them advance. In the 2009–10 UEFA Champions League, Bayern Munich won both round of 16 and quarter-finals on the away goal rule after drawing 4–4 on aggregate, by winning 2–1 at home and losing 3–2 away, against Fiorentina and Manchester United respectively. In the 2012–13 UEFA Champions League semi-finals, despite losing 4–1 in the first leg to Borussia Dortmund, Real Madrid would have been able to advance if at home it managed to hold Dortmund to 3–0; during the second leg Real Madrid scored two goals in the last ten minutes but were unable to score the third goal that would have sent them through to the final (Dortmund advanced 4–3 on aggregate). In the other semi-final, however, after Barcelona were defeated away by Bayern Munich 4–0, commentators considered Barcelona essentially eliminated because Bayern could seal the tie by scoring one away goal even if Barcelona managed to score five goals (Bayern managed a 3–0 win in the second leg to advance 7–0 on aggregate). The away goals rule can result in the "lead" of the two-legged tie swinging
