This article details the 2010–11 UEFA Europa League qualifying phase and play-off round.
The team that had the higher aggregate score over the two legs progressed to the next round.
In the event that aggregate scores finished level, the away goals rule was applied; i.e., the team that scored more goals away from home over the two legs progressed.
If away goals were also equal, then 30 minutes of extra time was played, divided into two 15-minute halves.
The away goals rule was again applied after extra time; i.e., if there were goals scored during extra time and the aggregate score was still level, the visiting team qualified by virtue of more away goals scored.
If no goals were scored during extra time, the tie was decided by a penalty shootout.
All draws were held at UEFA headquarters in Nyon, Switzerland.
[1] Matches may also be played on Tuesdays or Wednesdays instead of the regular Thursdays due to scheduling conflicts.
[2] The 37 winners of the play-off round qualified for the group stage to join the 10 losing teams from the Champions League play-off round, and the title holders, Atlético Madrid.
[3] In each round, teams were seeded based on their 2010 UEFA club coefficients.
[4] Prior to the draw, UEFA may form "groups" in accordance with the principles set by the Club Competitions Committee, but they are purely for convenience of the draw and do not resemble any real groupings in the sense of the competition, while ensuring that teams from the same association not drawn against each other.
