Puzzling gesture of coach Kim Sang Sik when substituting Dinh Bac right in the first half

As the first half of the Vietnam vs Singapore match was coming to a close, a scene off the pitch captured as much interest as the play on the field.

Coach Kim Sang-sik unexpectedly pulled Nguyen Dinh Bac out to rest at the 41st minute, simultaneously having a stern exchange with the young striker, sparking much discussion about the decisive gesture of the Korean strategist.

From the start of the match, Vietnam controlled the game and constantly pressured the opponent's half. Dinh Bac also had several chances, shooting consecutively in the 12th, 18th, and 21st minutes, but failed to convert them into goals. Although he moved actively and participated in combinations, the 2004-born striker still lacked precision in his final touches.

According to statistics, Dinh Bac played 41 minutes, took 4 shots, but only had an expected goals (xG) of 0.18. He touched the ball 12 times, completed 2 out of 4 passes, had one successful dribble, and won 2 out of 3 duels, yet did not create any clear chances for his teammates.

In the 41st minute, Coach Kim Sang-sik decided to bring on naturalized player Nguyen Tai Loc (Geovane) to replace Dinh Bac. Notably, as soon as the young striker left the pitch, the Korean coach approached to speak directly with his player with a serious expression. This image quickly spread on social media, leading many to believe that Kim was dissatisfied with Dinh Bac's performance in the first half.

Nevertheless, the early substitution is seen as a hallmark of Coach Kim Sang-sik's managerial style. When Vietnam created many chances but could not score against Singapore's packed defense, he chose to adjust the personnel just before the break instead of waiting until the end of the half.

Geovane's appearance shows that the coaching staff wanted to increase attacking firepower, while also sending a clear message that every player must meet tactical requirements to remain on the pitch. The stern gesture towards Dinh Bac is therefore seen as a reminder of discipline and decisiveness in the Korean strategist's team-building approach.
