A total of eight teams advancing from the second round (four group winners and four runners-up) will compete in the play-offs.
The quarter-finals, semi-finals and the finals will be played as two-legged ties, with home and away matches.
Each two-legged tie is considered as one match, meaning that if the first leg ends with a draw, no extra period is played.
However, if the aggregate score of both matches is a draw, the second leg will continue to be played with as many 5-minute periods as required to break the tie.
The second round group winners had the home advantage in the second leg.
