It was very controversial the referee at Bahrain vs Indonesia match, Indonesia failed to secure three points after conceding in the final minute of added time.
Hopefully, they learned from this and aim to secure victory with 2 goal difference or at the very least improve their concentration in the last minutes of a match so they don't concede late goals again. Complaining about unfairness can't guarantee anything IMO, even if governing bodies revise or stop using a controversial referee I don't think they'll change the results of a match that has ended. A football team can only depend on themselves to secure 3 points in this modern time.
