PAOK struggled to qualify against Anagennisi Giannitsa, with score 6–5 in penalty shoot-out. Eventually, a memorable fact took place, as HFF allocated the 1/5 of crude income of the final in favour of the aims of UNICEF.

Knockout phase
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 the aggregate score was level, the away goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced. 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.
