They're clear favourites to win Tuesday night's World Cup qualifier, but former Brisbane Roar captain Matt Smith has warned the Socceroos might struggle to contain Thailand's `Messi'.
Diminutive playmaker Chanathip Songkrasin, fittingly known as `Messi J', will be Thailand's tricky trump card at the Rajamangala National Stadium.
Former Socceroos defender Smith, who won three A-League titles the Roar, has himself been on the receiving end of Chanathip's cunning game.
Smith plays for Thai Premier League outfit Bangkok Glass while Chanathip steered champions Muangthong United to last season's title.
"In terms of their attacking strengths, he would be the one the Socceroos would have the most trouble with," Smith said.
"He's probably the cleverest, he's very good on the ball technically - he could definitely play at a higher level.
"He tries to get the ball into the smaller pockets and he's very comfortable linking with players around him.
"With a name like Messi J he literally floats around.
"He'll get himself into transition and look to counter-attack pretty quickly.
"He's good around the box and he can see a lot in terms of forward runners - and he can finish."
Smith expected Thai fans to come out in force on Tuesday, in what will be the first opportunity for the community to show public national support following a 30-day mourning period after the death of their king.
Despite Socceroos coach Ange Postecoglou predictingThailand would set up defensively, Smith felt their real strength lay in attack.
"I see it week in, week out," he said.
"They can defend also, but in terms of picking one over the other they attack very well."
Smith was on the sidelines watching Socceroos training over the weekend, taking up a rare opportunity to reunite with former Roar coach Postecoglou.
The 34-year-old has been attempting to implement Brisbane's football philosophy at Bangkok Glass, where he is their first foreign captain.
The team also has another Australian influence in new coach Aurelio Vidmar, appointed in August after his contract with the Australian national teams wasn't renewed.
"I think our club is ready for a coach of Aurelio's stature," Smith said.
"He's settled in well, now we've got a good opportunity in the pre-season to work on stuff he's been trying to implement."
