Tiebreakers
For FIFA World Cup qualifying stages using a home-and-away knockout format, the team that has the higher aggregate score over the two legs progresses to the next round.
In the event that aggregate scores finish level, the away goals rule is applied, i.e. the team that scored more goals away from home over the two legs progresses. If away goals are also equal, then thirty minutes of extra time are played, divided into two fifteen-minutes halves. The away goals rule is again applied after extra time, i.e. if there are goals scored during extra time and the aggregate score is still level, the visiting team qualifies by virtue of more away goals scored. If no goals are scored during extra time, the tie is decided by penalty shoot-out.
