Teams from the same UEFA Champions League Path group could not be drawn against each other, but teams from the same association could be drawn against each other. The draw also decided the home team for each round of 16 match.
* In the draws for the quarter-finals onwards, there were no seedings, and teams from the same UEFA Champions League Path group or the same association could be drawn against each other (the identity of all teams were not known at the time of the draw). The draws also decided the home team for each quarter-final, and the "home" team for administrative purposes for each semi-final and final (which were played at a neutral venue).
