He was a member of the Vietnamese team at a number of tournaments such as SEA Games 16 (1991) and Tiger Cup 1998.
Nguyễn Văn Dũng has worn the Hà Nam Ninh Industry since the beginning of his football career.
Reacting to the referee in 1990 caused both he (the captain) and Nam Dinh Textile to be banned for 1 year.
At that time, Nam Định Textile players chased and beat referee Nguyễn Thu in the second leg against Sông Lam Nghệ Tĩnh (28-3) and the whole team was disciplined and banned from playing for 1 year.
Later, thanks to his excellent performance at the 1998 national football championship and winning the title of Top Scorer at the age of 35, Nguyễn Văn Dũng was suddenly called back by Mr. Riedl to the team to attend the 1998 Tiger Cup and won the medal.
