Any game in the knockout stage that was undecided by the end of the regular 90 minutes was followed by thirty minutes of extra time (two 15-minute halves). If scores were still level after 30 minutes of extra time, there would be a penalty shootout (at least five penalties each, and more if necessary) to determine who progressed to the next round. As with every tournament since UEFA Euro 1984, there was no third place play-off.
Qualified teams
The top two placed teams from each of the two groups qualified for the knockout stage.
