The striker was on hand to convert a Dostonbek Khamdamov corner with his first touch of the game, after a 1-1 draw had forced the game into an additional 30 minutes.

While Uzbekistan’s victory saw them add to the AFC U-16 Championship title they won in 2012, it also brought the curtain down on a remarkable Vietnam campaign, one which will live long in the memory of the Southeast Asian nation’s supporters.

In decidedly wintry conditions at the Changzhou Olympic Sports Center, it was Uzbekistan who controlled the early proceedings, and they duly took the lead on eight minutes when a poorly marked Rustamjon Ashurmatov headed home Khamdamov’s outswinging corner.

Uzbekistan continued to press after the breakthrough, as both a Javokhir Sidikov header and Khamdamov’s effort from 20 yards forced Vietnam goalkeeper Bui Tien Dung into smart saves.

Despite struggling to fully impose themselves on the game, Vietnam briefly threatened to restore parity shortly after the half hour mark when Pham Xuan Manh’s excellent cross narrowly eluded the onrushing Phan Vanh Duc and Nguyen Quang Hai.

However, after seeing Azizjon Ganiev fire narrowly over, Vietnam drew level on the stroke of half-time. Nguyen Cong Phuong was brought down on the edge of the area, and from the resulting free-kick Quang Hai superbly curled the ball past the despairing dive of Botirali Ergashev to register his fifth goal of the tournament.
