Quarter-finals
6.09 The eight winners of the first knockout round contest the quarter-finals. The
quarter-final pairings are determined by means of a draw. The quarter-finals
are played under the cup (knock-out) system, on a home-and-away basis
(two legs). The team which scores the greater aggregate of goals in the two
matches qualifies for the semi-finals. Otherwise, the stipulations of Article 7
apply.
