Vicem Hai Phong has fallen to the bottom of the top-flight V-League after a 0-3 away defeat to Thanh Hoa in a 9th round match on Sunday.
In his visit to his former club, striker Hoang Dinh Tung of Hai Phong did not put in a great performance. In contrast, Le Quoc Phuong, a young Thanh Hoa player, had a great day.
Quoc Phuong scored the opener before making it possible for Brazilian midfielder Da Silva to double the score midway through the second half; and Ghanaian midfielder Michael Andrew wrapped up the 3-0 victory for Thanh Hoa in the final minutes.
The result was very disadvantageous for Hai Phong because both teams are languishing in the relegation zone.
Thanh Hoa remained in the 11th position of the 14-club league, with nine points while Hai Phong has only six points.
The 2007-08 champions Binh Duong came back from behind to beat Ninh Binh 3-1 at Go Dau Stadium, with striker Anh Duc scoring a brace.
