2020–21 UEFA Europa League knockout phase
In the knockout phase, teams from the same or nearby cities (e.g., Arsenal and Tottenham Hotspur) are not scheduled to play at home on the same day, due to logistics and crowd control. To avoid such scheduling conflict, adjustments have to be made by UEFA. For the round of 32, since both teams were drawn to play at home for the second leg, the home match of the team which were not domestic cup champions in the qualifying season, or the team with the lower domestic ranking (if neither team were the domestic cup champions, e.g. Tottenham Hotspur for this season), were moved from Thursday to a different day. For the round of 16, quarter-finals and semi-finals, if the two teams were drawn to play at home for the same leg, the order of legs of the tie involving the team which were not domestic cup champions in the qualifying season, or the team with the lower domestic ranking, will be reversed from the original draw.
