Extra time and penalty shootouts, explained: how knockout football splits a draw
In one line: Stoppage time versus extra time, the two halves of fifteen, and the shootout procedure - what the laws say, step by step.
A knockout match needs a winner, and football has a two-step ritual for finding one. Here is exactly how it works - and where each commonly confused term actually belongs.
Stoppage time is not extra time
Stoppage time (added time) happens in every match: the referee adds minutes at the end of each half for substitutions, injuries, celebrations and time-wasting. It tops the 90 up to what it should have been. Extra time happens only in knockout matches that must produce a winner on the day: two additional halves of 15 minutes each, played in full - there is no sudden-death golden goal in the modern laws; a goal in extra time does not end the match early.
Step two: kicks from the penalty mark
If the score is still level after extra time, the match goes to a penalty shootout. The procedure the laws set out: teams take five kicks each, alternating; if one team has scored more after both have taken their five, it ends there. If still level, it goes to sudden death - one kick each per round, and the first round where one scores and the other does not decides it. Only players on the pitch at the end of extra time may take a kick, and every kick is taken from the penalty mark with the goalkeeper on the line until the ball is struck.
The two-legged wrinkle
In two-legged ties (football's best-of-two), the tie is decided on aggregate score. The old away-goals rule - which valued an away goal double - was abolished by UEFA in 2021, so level aggregates now go straight to extra time and, if needed, the shootout. That is why commentary from before 2021 sounds different from modern coverage.
Why the shootout survives
Every alternative has been tried and retired: golden goal, silver goal, replays on demand. The shootout endures because it is decisive, quick, and brutal in a way the laws have learned to accept - a contest that is technically not football, resolving a football match. The players know it, the laws admit it, and nobody who has watched one forgets it.
The offside law does not apply differently in extra time, and neither does anything else - the laws run unchanged through all 120 minutes. The three-ideas explanation of that law is on the offside rule, explained, and the knockout structures that trigger all of this are mapped in how playoffs work and how the Champions League works.
