2018 AFF Championship
The 2018 AFF Championship was the 12th edition of the AFF Championship, the football championship of nations affiliated to the ASEAN Football Federation, and the 6th under the name AFF Suzuki Cup. This was the first time a new format has been applied with the group stage was played in a home-and-away format instead of be hosted in two nations from 2002 to 2016.
The final tournament ran from 8 November and ended on 15 December 2018. Through the agreement between AFF and East Asian Football Federation, the winner of the tournament will qualify for the AFF–EAFF Champions Trophy.
Thailand were the two-time defending champions, but lost to Malaysia in the semi-finals. Vietnam won the tournament by a 3–2 victory in the two-legged final against Malaysia to secure their second title, and subsequently qualified to meet 2017 EAFF E-1 Football Championship winner of South Korea in the 2019 AFF–EAFF Champions Trophy.
Format
In March 2016, it was reported that the AFF was mulling over changes to the tournament format due to the failure to attract big crowds for matches not involving the host nation. It was then confirmed by the AFF that starting with the 2018 edition, a new format would be applied. The nine highest ranked teams would automatically qualify with the 10th and 11th ranked teams playing in a two-legged qualifier. The 10 teams would be split in two groups of five and play a round robin system with each team playing two home and two away fixtures. A draw will be made to determine where the teams play while the format of the knockout round would remain unchanged.Home-Away matches division:
