A noteworthy thing is the statement of coach Kim Sang-sik at the press conference after the match. The important thing is that we have a balance in defense, attack and win, he said.
The question is, What is a balance between defense and attack? Viewers may not be too knowledgeable about the field, just enough to see the big difference with the ball rolling mostly on the field of U23 Laos. Specifically, the ball possession rate is 79%-21% (sometimes even up to 90%-10%); the total number of passes is 750-199; the number of shots is 20-2, in which the opponent has a shot from a distance.
So where is the balance? To some extent, balance can be understood as a good defense to prevent the opponent from attacking. But more strictly, experts can only feel secure if there is specific evidence. That is, the defense must know how to "perform" against opponents who are capable of causing pressure and organizing attacks, not in the style of "no need to sweat"...
As the Korean coach assessed, U23 Vietnam only pressed the opponent, not having to show their defensive rebound. Even the fact that central defender Hieu Minh appeared in the penalty area and scored twice also partly showed an "overwhelming" balance instead of a flip-off.
Of course, victory is still fun, but to be truly balanced - and steady - like a comeback, we need to be very careful, not subjective.
