The knockout phase involved the sixteen teams who finished in the top two in each of their groups in the group stage.[4]
Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that had the higher aggregate score over the two legs progressed to the next round. In the event that aggregate scores finished level, the away goals rule was applied, i.e. the team that scored more goals away from home over the two legs progressed. If away goals were also equal, then thirty minutes of extra time were played, divided into two fifteen-minutes halves. The away goals rule was again applied after extra time, i.e. if there were goals scored during extra time and the aggregate score was still level, the visiting team qualified by virtue of more away goals scored. If no goals were scored during extra time, the tie was decided by a penalty shoot-out. In the final, the tie was played as a single match. If scores were level at the end of normal time in the final, extra time was played, followed by penalties if scores remained tied.
