2005 ASEAN Club Championship

The 2005 ASEAN Club Championship or the 2005 ACC was the second edition of the ASEAN Club Championship, an international association football competition between domestic champion clubs sides affiliated with the member associations of the ASEAN Football Federation. This year, Tampines Rovers FC from Singapore won the championship. The champions of Liga Indonesia (Persebaya Surabaya) apparently did not enter due to a congested fixture list (AFC Champions League, Liga Indonesia and Indonesian Cup). The champions of Laos (MCTPC, aka Telecom and Transportation) and the champions of Philippines (National Capital Region FA) presumably renounced on participation for financial reasons.
