THAI PREMIER LEAGUE
The Thai Premier League (TPL) was formed in 1996, the same year Singapore embarked on its own professional football league.
While the S.League was more successful than the TPL in its initial years, with several Thai internationals plying their trade in Singapore, the TPL has jumped far ahead since.
In 2003, BEC Tero were losing finalists in the Asian Football Confederation (AFC) Champions League (ACL), with several other teams like Bangkok Glass, Buriram United and Chonburi also flying the flag for the Kingdom.
Warriors FC (then known as SAFFC) remain Singapore's best performing team in the ACL, dropping out in the opening group stage in 2010 with a win-draw-loss record of 1-4-1.
With big sponsors like Toyota, Coca-Cola and Chang Beer, Thai clubs now boast training facilities - with up to six training fields, gyms, boarding facilities and recovery areas - that Singapore clubs can only dream of.
Thailand's local clubs have invested seriously in youth development, a move that has seen its national youth teams feature prominently, even beyond South-east Asia.
In 2014, the Thai Under-23 side finished fourth at the Asian Games.
Its senior national team are now the top-ranked Asean nation, coming in at 121st. Singapore are the fourth-best in the region, ranked 148th, behind the Philippines (135) and Vietnam (146).
