If the aggregate score was level at the end of normal time of the second leg, extra time was played, and if the same number of goals was scored by both teams during extra time, the tie was decided by a penalty shoot-out.

Schedule
The schedule of the competition was as follows. Matches were scheduled for Thursdays though exceptionally could take place on Tuesdays or Wednesdays due to scheduling conflicts.
