Regulations
The regulations were the same as the previous season: in the semi-finals, the fifth-placed team faced the fourth-placed team, while the sixth-placed team faced the third. Each tie was played over two legs, with the team lower in the table hosting the first leg.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. If away goals were also equal, then thirty minutes of extra time would be played. The away goals rule would again be applied after extra time. If no goals were scored during extra time, the winner would be the best positioned team in the regular season.
