The clubs were ranked according to points and tie breakers were in the following order: • Points earned between the clubs in question • Goal Differential between the clubs in question • Points earned within the group • Goal Differential within the group • Goals For within the group The seven group winners along with the defending champion advanced to the quarter-finals. ;Knockout Round All eight clubs were randomly matched; however, the only restriction was that the clubs from the same country could not face each other in the quarter-finals. The games were conducted in 2 legs, home and away, and the aggregate score decided the match winner. If the aggregate score couldn't produce a winner, "away goals rule" was used. If still tied, clubs played extra time, where "away goals rule" still applied. If still tied, the game went to penalties. ==Participating clubs==
