Navibank Saigon came back from a goal down to beat Arema Indonesia 3-1 in their Group H second round match of the Asian Football Confederation Cup in Ho Chi Minh City Wednesday.
A hat-trick by Columbian striker Edison Fonseca helped Vietnam's National Cup holders get full points.
At the Thong Nhat Stadium, the Indonesians took the lead after just four minutes when the home team did not seem to be quite ready for the game.
But the goal seemed to be the wake-up call the hosts needed and their frantic efforts were rewarded 12 minutes before the break when Edison scored the leveler after the Arema goalkeeper failed to stop a powerful shot from Ekpe Aniekan Okon.
Navibank remained in overdrive in the second half as Edison scored twice more near the end of the match to wrap up a famous win.
In the other Group H match, Ayeyawady United of Myanmar also scored a 3-1 win over Malaysian champs Kelantan, with whom Navibank had drawn away on March 7.
The HCMC-based team, in second place with four points after two rounds, will next play on April 4, again at home, against group leaders Ayeyawady, who drew 1-1 with Arema in the first round.
In other action, V-League champs Song Lam Nghe An, who had lost 0-1 to Malaysia's Terengganu in the first round on March 6, drew 0-0 away with Singapore's Tampines Rovers in their Group F second round on Tuesday.
The AFC Cup is the continent's second-tier contest behind the AFC Champions League.
