Little information about football in this tiny sultanate reaches the outside world. However, the association was founded in 1959 and has an ordered structure. Brunei's national teams have appeared in many Asian and FIFA tournaments. Brunei made their international debut in the preliminary round for the 1986 FIFA World Cup? in Mexico, but struggled to make an impression and failed to win any points. A similar story unfolded during the qualifiers for the 2002 event. The domestic game has developed, however, mainly thanks to sponsorship deals with major companies. Originally consisting of 10 teams, the current B-League is now broken down into Premier I (10 teams) and Premier II (14 teams). In March 2005, the Sultan opened the nine-team ASEAN U-21 Championship, which was hosted by Brunei.
