To compensate:- The champions of association 13 were promoted from the third qualifying round to the group stage.
- The champions of association 16 were promoted from the second qualifying round to the third qualifying round.
- The champions of associations 48 and 49 were promoted from the first qualifying round to the second qualifying round.

Round and draw dates
All draws held at UEFA headquarters in Nyon, Switzerland unless stated otherwise.Seeding
The draws for the qualifying rounds, the play-off round and the group stage were all seeded based on the 2010 UEFA club coefficients. The coefficients were calculated on the basis of a combination of 20% of the value of the respective national association's coefficient for the period from 2005–06 to 2009–10 inclusive and the clubs' individual performances in the UEFA club competitions during the same period. Clubs were ordered by their coefficients and then divided into pots as required.In the draws for the qualifying rounds and the play-off round, the teams were divided evenly into one seeded and one unseeded pot, based on their club coefficients. A seeded team was drawn against an unseeded team, with the order of legs in each tie also being decided randomly. Due to the limited time between matches, the draws for the second and third qualifying rounds took place before the results of the previous round were known. The seeding in each draw was carried out under the assumption that all of the highest-ranked clubs of the previous round were victorious. If a lower-ranked club was victorious, it simply took the place of its defeated opponent in the next round. Moreover, in the third qualifying round and play-off round, champion clubs and non-champion clubs were kept separated. Prior to these draws, UEFA could form "groups" in accordance with the principles set by the Club Competitions Committee, but they were purely for convenience of the draw and did not resemble any real groupings in the sense of the competition, while ensuring that teams from the same association were not drawn against each other.
In the draw for the group stage, the 32 teams were split into four pots of eight teams, based on their club coefficients, with the title holder automatically placed into Pot 1. Each group contained one team from each pot, but teams from the same association could not be drawn into the same group. The draw was controlled in order to split teams of the same national association evenly between Groups A-D and Groups E-H, where the two sets of groups alternated between playing on Tuesdays and Wednesdays for each matchday.
In the draw for the first knockout round, the eight group winners were seeded, and the eight group runners-up were unseeded. A seeded team was drawn against an unseeded team, with the seeded team hosting the second leg. Teams from the same group or the same association could not be drawn against each other.
In the draws for the quarter-finals onwards, there were no seedings, and teams from the same group or the same association could be drawn with each other.
Qualifying rounds
In the qualifying and play-off rounds, teams played against each other over two legs on a home-and-away basis.The draws for the first two qualifying rounds were held on 21 June 2010 by UEFA General Secretary Gianni Infantino and Michael Heselschwerdt, Head of Club Competitions, while the draw for the third qualifying round was held on 16 July 2010 by UEFA General Secretary Gianni Infantino and Giorgio Marchetti, Competitions Director.
First qualifying round
The first legs were planned to be played on 29 and 30 June, and the second legs were played on 6 and 7 July 2010. However, the first match of the entire competition was cancelled due to the pitch being declared unfit.Second qualifying round
The first legs were played on 13 and 14 July, and the second legs were played on 20 and 21 July 2010.Third qualifying round
The third qualifying round was split into two separate sections: one for champions and one for non-champions. The losing teams in both sections entered the play-off round of the 2010–11 UEFA Europa League. The first legs were played on 27 and 28 July, and the second legs were played on 3 and 4 August 2010.Play-off round
The draw for the play-off round was held on 6 August 2010 by UEFA General Secretary Gianni Infantino and UEFA Competitions Director Giorgio Marchetti. The play-off round was split into two separate sections: one for champions and one for non-champions. The losing teams in both sections entered the group stage of the 2010–11 UEFA Europa League. The first legs were played on 17 and 18 August, and the second legs were played on 24 and 25 August 2010.Following a trial at the previous year's UEFA Europa League, UEFA announced that in both the 2010–11 and 2011–12 competitions, two extra officials would be used – with one on each goal line.
Group stage
The 32 clubs were drawn into eight groups of four on 26 August 2010 in Monaco. In each group, teams played against each other home-and-away in a round-robin format. The matchdays were 14–15 September, 28–29 September, 19–20 October, 2–3 November, 23–24 November, and 7–8 December 2010. The group winners and runners-up advanced to the round of 16, while the third-placed teams entered the round of 32 of the 2010–11 UEFA Europa League.If two or more teams were equal on points on completion of the group matches, the following criteria were applied to determine the rankings :
- higher number of points obtained in the group matches played among the teams in question;
- superior goal difference from the group matches played among the teams in question;
- higher number of goals scored away from home in the group matches played among the teams in question;
- superior goal difference from all group matches played;
- higher number of goals scored;
- higher number of coefficient points accumulated by the club in question, as well as its association, over the previous five seasons.
