Thailand — Singapore

A bet on "Both Teams to Score - Yes" in the match between Thailand and Singapore seems logical considering several factors. Firstly, despite Thailand winning all four matches in the group stage of the ASEAN Cup and not conceding a single goal, the team has issues with player fitness, as mentioned by coach Anthony Hudson. This could affect their defense, especially in a tense game against Singapore.

Singapore has shown decent form in their last five matches: two wins and two draws, indicating the team's ability to create chances and score. It's also worth noting that in the last ten encounters between these teams, Thailand has won all matches, but that doesn't mean Singapore won't be able to score at least one goal under increased pressure.

Thailand's captain Sarach Yooyen is indeed an important player in midfield, but his fitness may also impact the overall performance of the team. Given the above considerations, a bet on "Both Teams to Score - Yes" at odds of 2.05 seems justified.
