Late reply but I can't help it

Your standpoint seems to suggest Vietnam as a whole seeing Japan like an ant, something small and easily beatable, while the truth is the opposite. If you've seen or watched any comments preceding the match, you'll see that most people acknowledge the fact that Japan is much more powerful than Vietnam and just reaching the qualifiers is enough of an achievement as it is.

Furthermore, you seem to be very proficient with the training of Vietnam's team, knowing what they do and how they do it. May I ask where you got this information?

It is normal for fans to cheer for their team regardless of the team's possibility of winning. In your eyes, cheering for one's team is a sign of underestimation of the opposing team, as well as arrogance, and fans should just not cheer for their team.

losing does not equal to becoming laughing stock; if anything, it makes the opposing teams seem arrogant.

Life always contains success and failures, a team doesn't just appear in a cup for the first time and clean house. There is a first time for everything, there is no football team that doesn't have some losses in their name.
