Destiny not in their hands, but both Lions and Garudas still have faith
Both Singapore and Indonesia still believe that they can clinch qualification even though they will need help from Thailand in the last round of Group A matches.
As it stands, all Philippines have to do is to win against Thailand and they will finish second in Group A. But should Philippines fail to do that then the team that gets all three points in the Singapore against Indonesia match will go through as the group's runners up.
That is recognised by both teams' head coaches, who claim they are going for the win.
For Singapore's V. Sundramoorthy, he is confident that they will be able to take advantage of Indonesia's weaknesses.
"We have analysed Indonesia and looked at their weaknesses," Sundram said.
"We will try to plan and exploit their weaknesses. We'll also look at their strengths and come up with a game plan.
"We've had two good matches, we were unlucky against Thailand. Indonesia are a very good team with good players. We are focusing on our own team, trying to get the win."
A key point to stopping Indonesia will be to keep their captain Boaz Salossa quiet throughout the 90 minutes, which was what Sundram pointed out as well.
"We know Boaz Salossa is a very good player... we must find a way to stop him."
As for Indonesia's Alfred Riedl, he believes that they have to be wary of a Singapore side looking to come out to attack.
In the previous two matches, the Lions have been playing a defensive brand of football, and games involving them have yielded only one goal in total.
However, with the Lions gunning for a win, Riedl expects them to throw caution to the wind, and that is something they have to be careful of.
"Looking at the previous game, Singapore did not score any goals and conceded in the dying minutes. In the first match against Philippines, Singapore played open football with 11 players, then played defensively after to get the draw," Riedl said.
"In the second match, Thailand are powerhouses but Singapore made it difficult for them and the tactics almost worked.
"This time they have to win so I expect them to play similar to their early showing against Philippines. We are prepared. Both teams have to win and this will open the game up."
But the Indonesians might be hindered by injuries, with Riedl revealing that several players are carrying knocks and are doubts for the match.
"Some players have slight injuries," Riedl said.
"(Stefano) Lilipaly and Rizky (Pora) could not train yesterday. We will see tonight. If they cannot train, they will not play tomorrow.
"We will take no risks with players who are not 100 per cent."
