Group Stage

A total of 28 clubs were divided into 7 groups of four, based on region i.e. East Asian and Southeast Asian clubs were drawn in groups E to G, while the rest were grouped in groups A to D. Each club played double round-robin (home and away) against fellow three group members, a total of 6 matches each. Clubs received 3pts for a win, 1pt for a tie, 0pts for a loss. The clubs were ranked according to points and tie breakers were in the following order:

• Points earned between the clubs in question
• Goal Differential between the clubs in question
• Goals For between the clubs in question
• Points earned within the group
• Goal Differential within the group
• Goals For within the group

The seven group winners along with the defending champion advanced to the quarter-finals.

Knockout Round

All 8 clubs were randomly matched; however, the only restriction was that the clubs from the same country could not face each other in the quarter-finals. The games were conducted in 2 legs, home and away, and the aggregate score decided the match winner. If the aggregate score couldn't produce a winner, "away goals rule" was used. If still tied, clubs played extra time, where "away goals rule" still applied. If still tied, the game went to penalties.

For this year the competition was restricted to clubs from countries considered 'mature' in the 'Vision Asia' paper of AFC President Mohamed Bin Hammam, with clubs from 'developing' countries entering the newly created AFC Cup and 'emerging' nations to enter the AFC President's Cup from 2005 onwards.
