It's D-Day for the Socceroos but a confident Australian coach Graham Arnold believes two crucial factors will favour his team when it attempts to beat Thailand here on Monday night and stay alive in the Asian Cup.
For the first time in the tournament an Australian match will be kicking off in the evening at 7.35pm (local time) when conditions are much cooler after the Socceroos' first two matches kicked off at 5.20pm (local time) - still in the heat and humidity of the day.
And after playing in front of tiny crowds in their first two matches against Oman and Iraq - which seemed to affect the players - the clash against Thailand is expected to be played in front of a full house of around 60,000 at Rajamangala Stadium as the 122nd ranked co-hosts attempt to reach the knockout stages of this competition for the first time.
Just a draw will be good enough for Thailand to go through and for tournament favourites Australia to be sent packing but Arnold believes the circumstances of the game are tailor-made for his under-achieving team to finally produce its best.
In particular Arnold is convinced the later kick-off and cooler conditions will suit his side.
"The last two games were a 5.20pm kick-off and the conditions were tough with the sun still out," he said.
"But a 7.30pm kick-off, the conditions are much cooler and the humidity is less so I imagine that will be a lot better for us.'
Even Thailand coach Chanvit Polchovin agrees, saying the later kick-off neutralised his team's home ground advantage.
"One of the weaknesses of the Australian team is that they can not handle the weather in Thailand very well," he said.
"But this time we are not playing in the early evening, we are playing at 7:30 so the heat and humidity will not help us."
"So we may see that Australia this time will be in their top form."
Arnold also believes the expected big crowd will work in Australia's favour given the team is full of players used to playing their club football in front of massive crowds in Europe whereas the Thailand team and players - most of whom play their club football at home - rarely play in front of big crowds.
"Hopefully there will be a much bigger crowd tonight and a much bigger atmosphere and that will spur our boys on even more," Arnold said.
"And that will put a bit of pressure on the Thai team because they are playing in front of their own supporters and the expectations on them are high."
