The Arab Crown, known as the Arab Club Champions Cup, is an annual regional club soccer competition organized by the Arab Football Association.
The tournament has been held 29 times, with Saudi Arabia taking the title eight times. The tournament is contested by 37 clubs from 22 Arab countries, with qualifying rounds to select the top sixteen, a group stage to determine the top eight, and then three rounds of single-elimination matches to determine the champion. The Arabian Championship is an "unofficial" tournament, an inter-regional tournament organized by the Arab Football Federation, which is not recognized by FIFA and is not an official tournament under its auspices.
The Arab Champions League, a regional soccer tournament held annually in the Arab region, is organized by the United Arab Soccer Association and has been played since 1980, with a format similar to that of the Champions League. The participating teams are mainly composed of strong teams from Arab countries in Africa and Asia. The Arab Champions League is the highest level of competition in the Arab world.
The Arab Champions League utilizes a group stage + knockout stage format. Participating teams are divided into groups of four teams each. In the group stage, each team will play a home-and-away match against the other teams in the group for a total of six rounds of matches. At the end of the group stage, the top two teams from each group will advance to the knockout stage.
The Saudi Champions Cup follows the rules of the Fédération Internationale de Football Association (FIFA) with some special provisions. Each team can register up to 30 players, but only 18 players can be registered for each match. Matches last 90 minutes, divided into two 45-minute halves, with a 15-minute halftime break. If the game goes into extra time, each half is 15 minutes long with a 5 minute intermission.
