Gustavo acquired Vietnamese citizenship and took the name Do Phi Long.
On the morning of December 11th at the Da Nang Department of Justice, the 1.95m tall central defender received Decision 2332/QD-CTN granting him citizenship and allowing him to play under the name Do Phi Long; Da Nang has opened one foreign player slot.
On the morning of December 11th at the Da Nang City Department of Justice, center-back Gustavo Sant Ana received Decision No. 2332/QD-CTN from the President of Vietnam granting him Vietnamese citizenship. From this moment on, the player born in 1995 will play and contribute under his new name: Do Phi Long. With a height of 1.95m, he is expected to strengthen the aerial defense of the Vietnamese national team, and at the same time help Da Nang Club free up a foreign player slot for the second half of the V-League season.
Legal milestones and the journey to integration.
The decision to grant Vietnamese citizenship marks a milestone after Gustavo's nearly six-year journey with Vietnamese football. Since 2019, he has played for SLNA, Thanh Hoa, and Saigon FC before joining Da Nang FC. In the naturalization application documents, his clubs and the VFF emphasized his professionalism, Vietnamese language skills, and desire to contribute to the country long-term.
Playing as a domestic player is not only a recognition of his efforts to integrate but also opens up new opportunities for Do Phi Long's development in the V-League environment, where physical competition and aerial play are increasingly decisive.
Tactical Corner: Air Combat and Team Needs
At 1.95m tall, Do Phi Long has a clear advantage in defending against aerial balls and set pieces. He is a key addition that coach Kim Sang-sik hopes will strengthen the defense against opponents who tend to prioritize physical strength. In the context of some regional teams, such as Indonesia, continuously "Westernizing" their squads, increasing average height and aerial ability are crucial criteria.
At the club level, Do Phi Long's physique and experience playing in the V-League help him adapt quickly to the pace and intensity of defense. His ability to anticipate second balls, shield the penalty area, and create advantages in set pieces are added values that Da Nang FC can immediately utilize.
Impact on Da Nang Club: Managing foreign player quotas
Switching to domestic player status allows Da Nang to free up a valuable foreign player slot for the remainder of the season. This gives the coaching staff more options to strengthen their attacking firepower or add depth to positions that are lacking. Strategically, balancing the quality of experienced V-League domestic players with foreign players for attacking plays is key for the team from the Han River in the fiercely contested second half of the season.
National Team Selection Pathway: FIFA Requirements and Timeline
In terms of international procedures, Do Phi Long has met the requirement of residing in the country for 5 consecutive years as stipulated by FIFA. If he completes the relevant registration steps, he – along with Do Hoang Hen (Hendrio) – could be considered for his national team debut during the training camp in March next year. This is a reasonable timeframe for coach Kim Sang-sik to assess the suitability of these new players for the current defensive structure.
In addition, the naturalization waiting list still includes notable names such as Janclesio and Geovane Magno. If the procedures progress smoothly, the depth of personnel and competition for positions in the Vietnamese national team will be strengthened, opening up more tactical options in the near future.
Notable milestones
- 2019: Began playing in Vietnam, successively playing for SLNA, Thanh Hoa, and Saigon FC.
- 11/12: Received Decision No. 2332/QD-CTN, officially acquired Vietnamese citizenship and competed under the name Do Phi Long.
- March of next year: May be considered for the Vietnam National Team training camp if registration steps are completed.
With his naturalization milestone, Do Phi Long brings double value: an immediate solution for Da Nang and an additional option for the national team's defensive structure. The rest depends on the speed of completing the procedures and how he translates his physical advantage into effective performance as the V-League enters its crucial stage.
