The signing ceremony saw the participation of Hoang Anh Gia Lai boss Doan Nguyen Duc alongside representatives from Sint-Truidense FC.
During the event, Sint-Truidense FC representatives presented Phuong with the number 15 shirt that he will wear next season.
Explaining their reasons for signing Phuong, a club representative said it was partially based on the rapid growth currently underway in Asian football with Vietnam leading the way in that development.

Upon addressing the ceremony, Phuong expressed his hope that he will be able to adapt to the new environment and prove himself to the club after enduring several failures in his previous experience at overseas clubs.
The Vietnamese forward believes that he will definitely succeed in Belgium.
