Football tournament group stage
The 2017 AFC Cup group stage was played from 20 February to 31 May 2017. A total of 34 teams competed in the group stage to decide the 11 places in the knockout stage of the 2017 AFC Cup.
Draw
The draw for the group stage was held on 13 December 2016, 14:30 MYT (UTC+8), at the Hilton Petaling Jaya in Petaling Jaya, Malaysia. The 36 teams were drawn into nine groups of four: three groups each in the West Asia Zone (Groups A–C) and the ASEAN Zone (Groups F–H), and one group each in the Central Asia Zone (Group D), the South Asia Zone (Group E), and the East Asia Zone (Group I). Teams from the same association in the West Asia Zone and ASEAN Zone could not be drawn into the same group.
Due to the withdrawal of teams in the ASEAN Zone and the East Asia Zone after the draw, only 34 teams competed in the group stage, with Groups H and I having only three teams.
The seeding of each team in the draw was determined by their association and their qualifying position within their association. The mechanism of the draw was as follows:
For the West Asia Zone, a draw was held for the five associations with two direct entrants (Iraq, Syria, Jordan, Bahrain, Lebanon) to determine the three associations occupying seeds 1 and 2, with seeds 1 placed in order for Groups A, B and C, and the two associations occupying seeds 3 and 4, with seeds 3 placed in order for Groups A and B. The remaining teams were then allocated to groups according to the rules set by AFC.
For the ASEAN Zone, a draw was held for the four associations with two direct entrants (Vietnam, Malaysia, Myanmar, Philippines) to determine the three associations occupying seeds 1 and 2, with seeds 1 placed in order for Groups F, G and H, and the one association occupying seeds 3 and 4, with seed 3 placed in Group F. The remaining teams were then allocated to the groups according to the rules set by AFC.
For the Central Asia Zone, the South Asia Zone, and the East Asia Zone, no draw was held, and the teams were allocated to the groups according to their association ranking published on 30 November 2016.
The following 34 teams entered into the group stage draw, which included the 29 direct entrants and the five winners of the play-off round of the qualifying play-offs, whose identity were not known at the time of the draw. Originally there were 30 direct entrants and six winners of the play-off round, but there were one fewer direct entrant in the ASEAN Zone due to the withdrawal of one team, and the East Asia Zone qualifying play-offs were not played due to the withdrawal of three teams.
In the group stage, each group was played on a home-and-away round-robin basis. The following teams advanced to the knockout stage:
The winners of each group and the best runners-up in the West Asia Zone and the ASEAN Zone advanced to the Zonal semi-finals.
The winners of each group in the Central Asia Zone, the South Asia Zone, and the East Asia Zone advanced to the Inter-zone play-off semi-finals.
Tiebreakers
The teams were ranked according to points (3 points for a win, 1 point for a draw, 0 points for a loss). If tied on points, tiebreakers were applied in the following order (Regulations Article 10.5):
Goals scored in head-to-head matches among tied teams;
Away goals scored in head-to-head matches among tied teams;
If more than two teams are tied, and after applying all head-to-head criteria above, a subset of teams are still tied, all head-to-head criteria above are reapplied exclusively to this subset of teams;
Goal difference in all group matches;
Goals scored in all group matches;
Penalty shoot-out if only two teams are tied and they met in the last round of the group;
Disciplinary points (yellow card = 1 point, red card as a result of two yellow cards = 3 points, direct red card = 3 points, yellow card followed by direct red card = 4 points);
The schedule of each matchday was as follows (W: West Asia Zone; C: Central Asia Zone; S: South Asia Zone; A: ASEAN Zone; E: East Asia Zone). Matches in the West Asia Zone were played on Mondays and Tuesdays, while matches in the Central Asia Zone, the South Asia Zone, the ASEAN Zone, and the East Asia Zone were played on Tuesdays and Wednesdays.
Source: AFC Note: Due to Group H having only three teams, the results against the fourth-placed teams in Groups F and G are not considered for this ranking.
Notes
^ The seeding of the first and second group stage teams from Iraq, Syria, Jordan, Bahrain, and Lebanon were determined by draw.
^ The seeding of the first and second group stage teams from Vietnam, Malaysia, Myanmar, and Philippines were determined by draw.
Lanexang United (Laos) withdrew from the group stage after the draw (originally drawn in Group H), and were not replaced, and only 11 teams competed in the ASEAN Zone group stage.
^ Rovers (Guam) and Taipower (Chinese Taipei) withdrew from the group stage after the draw (both originally drawn in Group I), and Tatung (Chinese Taipei) withdrew from the qualifying play-offs, and thus Kigwancha (North Korea) and Erchim (Mongolia) advanced directly from the play-off round and preliminary round respectively to the group stage to replace them, and only three teams competed in the East Asia Zone group stage, and the East Asia Zone qualifying play-offs were not played.
The standby teams would replace a team from the same association which played in the AFC Champions League qualifying play-offs and advanced to the AFC Champions League group stage. There were no standby teams from Bahrain (for Al-Hidd).
