Indonesian players should be forget this result and focus for upcoming match against China and so far China is the weakest team in group C because until 3 matches they still unable to collect points and hopefully this time Indonesia can beat China and gets 3 points from this match
I'm pretty sure that's what the captain said in one of the interviews. He said in football you can't expect fairness to win you the game, so they need to move on and prepare for the next match asap. I think the chance for them to go to the next round is still high anyway since they will face Bahrain again in Jakarta. Who knows maybe they'll get another 3 points from Australia or Arab too, or steal another point and finish with 10 points or so. It's still too early for them to give up.
I am sure they can maintain their mentality very well, even this very disappointing result can be a motivation for them to be more effective. I think it will be a different story when they can take advantage of the opportunities that occur in extra time, and if it can be used as a goal then it will be a game killer. Indeed, in football you cannot expect to get the fairest justice, sometimes that factor makes the results not in accordance with expectations. I even saw an official post from Bahrain noting that the goal they created occurred in the 90+6 minute, it was very funny. This is a lesson for Indonesia that when they have improved there are things that will bother them.
Yes, all the less than satisfactory results from the matches that have been played will be able to provide learning and also motivation to all players to be able to perform better later when Indonesia plays at home, this is also an opportunity for Indonesia to be able to beat Bahrain more absolutely.
Previously, Bahrain had also received controversy due to several incidents carried out by supporters when they faced Japan and now it has happened again in the match against Indonesia with several ridiculous things that should not have been done, but this is football and also competition where there are always things beyond reason that will happen.
However, Indonesia does not need to worry because there are still many opportunities and of course all hopes can still be had for Indonesian fans to see their country compete in the 2026 World Cup, I think for the group C only Japan is difficult team to match and for several other team I believe they can still be mainstay for Indonesia to continue to get points from each match.
