It was an enough eventful year, that was marked by hard confrontations in the cases of "strong" pairs.

Each tie in the knockout phase, apart from the first two rounds and the final, was played over two legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round.

If away goals were also equal, then extra time was played. 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 advanced by virtue of more away goals scored. If no goals were scored during extra time, the winners were decided by a penalty shoot-out. In the first two rounds and the final, which were played as a single match, if the score was level at the end of normal time, extra time was played, followed by a penalty shoot-out if the score was still level.
