- Ball in attacking third/penalty area - Measure time the ball is in the given area (regardless of possession), team with higher time advances.
- Coin flip/Drawing of lots - Team winning the "lottery" advances.
- Corner kicks - Team with more corner kicks advances.
- Discipline points - Team with least discipline points advances (can be cards or a combination of cards and fouls committed).
- ET + PSO - Today's system.
- GK touches - Team whose GK touched the ball in the box least number of times advances.
- Higher seeded - Team with better record in group stage/higher ranking pre-tournament.
- Kicks before ET - PSO takes place before the start of ET (used only if ET ends in a tie).
- PSO (no ET) - Skip ET and go straight to PSO.
- Time of possession - Team with greater time of possession in attacking half advances.
My picks are 6, 1, 10. All of them reward a team for attacking and punish teams that keep playing the ball back to the keeper or hold it without an attempt to push forward. I really don't like 2 & 9. The others are tiebreakers but don't really help the game.
