Coach Troussier and the 'problem' without Ngoc Hai and Tien Linh
The Vietnam team will not have the services of Ngoc Hai and Tien Linh in the 2023 Asian Cup journey. With no other choice, coach Troussier will have to promote U23 players to replace them.
Coach Troussier and his colleagues had high hopes that Ngoc Hai and Tien Linh would return soon to be in time for Qatar. However, this was impossible and the French coach was forced to consider alternative plans.

In the defense, coach Troussier may have a headache choosing 3 central defenders at the moment. According to coach Troussier's preferred arrangement, the duo Thanh Binh and Tuan Tai are chosen as the top central defenders.
But as many fans have seen, the form of these players is showing signs of decline at club level. The Cong Viettel have lost their last 3 matches in December.

The central defender chosen to replace Ngoc Hai was Viet Anh, but the Hanoi Police player's ability to read situations was also something that made coach Troussier unsatisfied. In the two matches against the Philippines and Iraq, Viet Anh's ability to catch people made fans worried.
The remaining central defenders like Duy Manh are also not sure to recover from their injuries after a long time on the bench, not allowed to play by Hanoi FC. Duy Manh, if healthy, would be a good choice for coach Troussier, but this season the 27-year-old player has only played 2 matches in the V-League.
The central defenders Tuan Duong and Ngoc Bao have little experience in international competition and may not yet understand the coach's tactics. That is why the French coach may need students from the U23 Vietnam team who are ready, such as Ngoc Thang, Nguyen Hoang, and Quang Thinh.
In the Asian Cup, the attack line is even more emphasized, so the Vietnamese team must constantly face the storm from strong opponents. Although the tournament has not yet started, it can be seen that the pressure is weighing heavily on coach Troussier and his team. The Vietnamese team does not have a solid foundation before the upcoming difficult journey in Qatar.
The attack line when Tien Linh and Thanh Nhan are absent due to injury can also create conditions for other U23 Vietnam players.
At this time, coach Troussier only has real strikers like Tuan Hai, Van Toan, Dinh Bac, Van Tung. The Vietnam team may have to add at least one U23 player, if any, the opportunity will open up for Van Truong and Vi Hao.
The Vietnamese team must diversify their attacking tactics when necessary. Against strong opponents, coach Troussier will rotate the strikers to make things difficult for the opponent.
In case of losing the first goal, the replacement of personnel in the attack line will also be considered first./.
