Qualifying rounds

In a new system for the Champions League, there were two separate qualifying tournaments. The Champions Path (which started from the first qualifying round) was for clubs which won their domestic league and did not automatically qualify for the group stage, while the Non-Champions Path (which started from the third qualifying round) was for clubs which did not win their domestic league and did not automatically qualify for the group stage.

In the qualifying phase and the play-off round, teams played against each other over two legs on a home-and-away basis.

The draw for the first and second qualifying rounds, conducted by UEFA President Michel Platini and UEFA General Secretary David Taylor, was held on 22 June 2009, and the draw for the third qualifying round, conducted by UEFA Competitions Director Giorgio Marchetti and Head of Club Competitions Michael Heselschwerdt, was held on 17 July 2009. For the draws, clubs were separated into seeded and unseeded teams based on their club coefficient. Because the draws for the second and third qualifying rounds took place before the previous round was completed, the teams were seeded assuming the seeded side in the previous round would be victorious.

First qualifying round The first legs were played on 30 June and 1 July, and the second legs were played on 7 and 8 July 2009.

Second qualifying round The first legs were played on 14 and 15 July, and the second legs were played on 21 and 22 July 2009.

Partizan's 8–0 win over Rhyl in the second leg equalled the record for the largest margin of victory in the current Champions League format.

, the second leg between Stabæk and Tirana was under investigation by UEFA and German authorities for possible match-fixing.

Third qualifying round The third qualifying round was split into two separate sections: one for champions and one for non-champions. The first legs were played on 28 and 29 July, and the second legs were played on 4 and 5 August 2009. The losing teams in both sections entered the play-off round of the 2009–10 UEFA Europa League.

Play-off round

An extra qualifying round, the play-off round, was introduced from this season. The teams were split into two separate sections: one for champions and one for non-champions. The draw for the play-off round, conducted by UEFA General Secretary David Taylor and UEFA Competitions Director Giorgio Marchetti, was held on 7 August 2009. For the draw, clubs were separated into seeded and unseeded teams based on their club coefficient. The first legs were played on 18 and 19 August, and the second legs were played on 25 and 26 August 2009. The losing teams in both sections entered the group stage of the 2009–10 UEFA Europa League.

Group stage

The draw for the group stage was held at the Grimaldi Forum in Monaco on 27 August 2009. A total of 32 teams were drawn into eight groups of four. Teams were divided into four pots, based on their club coefficient. Clubs from the same pot or the same association cannot be drawn into the same group.

In each group, teams played against each other home-and-away. The matchdays were 15–16 September, 29–30 September, 20–21 October, 3–4 November, 24–25 November, and 8–9 December 2009. The top two in each group advanced to the knockout phase, and the third-placed teams entered the round of 32 of the 2009–10 UEFA Europa League.

Based on Article 7.06 in the UEFA regulations, 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.

APOEL, AZ, Debrecen, Rubin Kazan, Standard Liège, VfL Wolfsburg, Unirea Urziceni and Zürich all made their debuts in the group stage.

Knockout phase

In the knockout phase, teams played against each other over two legs on a home-and-away basis, except for the one-match final. The mechanism of the draws for each round was as follows: In the draw for the round of 16, the eight group winners were seeded, and the eight group runners-up were unseeded. The seeded teams were drawn against the unseeded teams, with the seeded teams 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 and semi-finals, there were no seedings, and teams from the same group or the same association could be drawn against each other. As the draws for the quarter-finals and semi-finals were held together before the quarter-finals were played, the identity of the quarter-final winners was not known at the time of the semi-final draw. A draw was also held to determine which semi-final winner was designated as the "home" team for the final (for administrative purposes as it was played at a neutral venue).
