In the knockout stage, if the scores are level at full-time, Fictional Extra Time comes into play:

• One goal scored for the team with most possession.
• One goal scored for the team with the most shots on target.
• One goal scored for the team who scored first in normal time.

If scores are still level, team with most possession + shots on target gets one extra goal (see original FET rule: https://smtop100.blog/youth-cup-format-rules/youth-cup-knock-out/)
