Europa League Format
Until 2014/2015
Qualifying phase
Qualifying-phase matches are played according to the knockout system, with each club playing each opponent twice, in home and away matches. Clubs from the same association cannot be drawn against each other. The team which scores the greater aggregate of goals in the two matches qualifies for the next stage (second qualifying round, third qualifying round, fourth qualifying round or group stage, as applicable).
Group stage
Once the qualifying phase have been completed, the 48 remaining clubs are drawn into 12 groups of four. Clubs from the same association cannot be drawn into the same group. Each club plays one home and one away match against each other club in its group. Three points are awarded for a win, one point for a draw, and none for a defeat. If two or more teams are equal on points on completion of all the group matches, the following criteria are applied to determine the rankings (in descending order):
a) higher number of points obtained in the group matches played among the teams in question;
b) superior goal difference from the group matches played among the teams in question;
c) higher number of goals scored in the group matches played among the teams in question;
d) higher number of goals scored away from home in the group matches played among the teams in question;
e) if, after having applied criteria a) to d), two teams still have an equal ranking, criteria a) to d) are reapplied exclusively to the matches between the two teams in question to determine their final rankings. If this procedure does not lead to a decision, criteria f) to h) apply;
f) superior goal difference from all group matches played;
g) higher number of goals scored from all group matches played;
h) higher number of coefficient points accumulated by the club in question, as well as its association, over the previous five seasons
The 12 group-winners and the 12 runners-up from the group stage qualify for the round of 32. The clubs that finish this stage in third and fourth position in their group are eliminated.
Round of 32
The 24 clubs qualified from the group stage will be joined by the 8 clubs that finish the group stage of the UEFA Champions League in third position. The round of 32 pairings are determined by means of a draw. This round is played under the knockout system, on a home and away basis (two legs). The UEFA administration ensures that the following principles are respected.
a) Clubs from the same association cannot be drawn against each other.
b) The 12 UEFA Europa League group-winners and the 4 best third-ranked teams in the UEFA Champions League group stage are drawn against the 12 UEFA Europa League group runners-up and the remaining third-ranked teams in the UEFA Champions League group stage.
c) The winners and runners-up of the same group cannot be drawn against each other.
d) The UEFA Europa League group-winners and the four best third-ranked in the UEFA Champions League group stage play the return leg at home.
The team which scores the greater aggregate of goals in the two matches qualifies for the round of 16.
Round of 16
The 16 winners of the round of 32 contest the round of 16, for which the pairings are determined by means of a draw. The round of 16 is played under the knockout system, on a home-and-away basis (two legs). The team which scores the greater aggregate of goals in the two matches qualifies for the quarter-finals.
Quarter-finals
The eight winners of the round of 16 contest the quarter-finals, for which the pairings are determined by means of a draw. The quarter-finals are played under the knockout system, on a home-and-away basis (two legs). The team which scores the greater aggregate of goals in the two matches qualifies for the semi-finals.
Semi-finals
The four winners of the quarter-finals contest the semi-finals, for which the pairings are determined by means of a draw. The semi-finals are played under the knockout system, on a home-and-away basis (two legs). The team which scores the greater aggregate of goals in the two matches qualifies for the final.
Final
The final is played as one single match at a neutral venue. If the result stands as a draw at the end of normal playing time, extra time of two periods of 15 minutes is played. If one of the teams scores more goals than the other during extra time, that team is declared the winner. If the two teams are still equal after extra time, the winner is determined by kicks from the penalty mark.
Away goals and extra time under the knockout system
For matches played under the knockout system, if the two teams involved in a tie score the same number of goals over the two legs, the team which scores more away goals qualifies for the next stage. If this procedure does not produce a result, i.e. if both teams score the same number of goals at home and away, two 15-minute periods of extra time are played at the end of the second leg. If, during extra time, both teams score the same number of goals, away goals count double (i.e. the visiting club qualifies). If no goals are scored during extra time, kicks from the penalty mark determine which club qualifies for the next stage.
Seeding of clubs
The UEFA administration seeds clubs for the qualifying phase and the group stage, in accordance with the club coefficient rankings established at the beginning of the season and with the principles set by the Club Competitions Committee. If, for any unforeseen reason, any of the participants in such rounds are not known at the time of the draw, the coefficient of the club with the higher coefficient of the two clubs involved in an undecided tie will be used for the purposes of the draw. If the titleholder takes part in the group stage, it is always the top seed.
For seeding purposes, rankings are drawn up on the basis of a combination of 20% of the value of the respective association's coefficient for the last five seasons inclusive and the clubs' individual performances in the UEFA club competitions during the same period. Each club retains the cumulative number of points obtained during this period.
When seeding is applicable, an equal number of clubs will be seeded and unseeded.
Ties
The ties are determined by means of a draw. The club drawn first plays the first leg of the tie at home. The UEFA administration may decide that a tie be played in one leg, if circumstances so require, and will set the principles for determining the winner accordingly.
Number of clubs per UEFA member association
In special circumstances, the winner of another official domestic competition may be entered for the UEFA Europa League instead of the lowest ranking top domestic league representative.
If the winner of the domestic cup qualifies for the UEFA Champions League, the domestic cup runner-up qualifies for the UEFA Europa League at the stage initially reserved for the lowest ranking top domestic league representative (or the winner of another official domestic competition). Should both the winner and the runner-up of the domestic cup qualify for the UEFA Champions League, the association concerned may enter for the UEFA Europa League the club which finishes the top domestic league immediately below the other club or clubs which qualify for the UEFA Europa League. In both cases, the access stage initially reserved for the domestic cup winner is reserved for the club which finishes the domestic league in the highest position out of all the clubs which qualify for the UEFA Europa League from the association concerned. Each representative of the domestic league will then enter the competition at the stage initially reserved for the domestic league representative ranked immediately above it.
In addition:
a) Three clubs are admitted to the first qualifying round of the competition on the basis of the UEFA Respect Fair Play Assessment.
b) The 15 clubs eliminated in the third qualifying round of the UEFA Champions League are admitted to the play-offs for the UEFA Europa League.
c) The ten clubs eliminated in the play-offs for the UEFA Champions League are admitted to the group stage of the UEFA Europa League.
d) The eight clubs which finish the group stage of the UEFA Champions League in third place in their group are admitted to the UEFA Europa League round of 32.
Titleholder
Unless the UEFA Europa League titleholder qualifies for the UEFA Champions League through its domestic championship, it is guaranteed a place in the group stage of the UEFA Europa League. If the titleholder qualifies for the UEFA Europa League through its domestic competitions, the number of places to which its association is entitled in the UEFA Europa League does not change. If the UEFA Europa League titleholder does not qualify for either the UEFA Champions League or UEFA Europa League through its domestic competitions, its participation in the UEFA Europa League is not at the expense of the contingent of its association.
