Riding high from their thumping 5-2 win over Yangon United in their previous match, the visitors took time to settle and it was the home side who had the first real opportunity of the game as Anderson Zogbe failed to direct his effort on target from Khim Borey’s corner.
Hanoi came into the game as the half went on and star striker Pape Omar Faye had two chances to open the scoring, but saw one effort deflected while he had an air swing on the other.
Ten minutes before the break the visitors struck with a nice passing move involving Nguyen Quang Hai, Pape Omar Faye and Moses Oloya which was finished off by the Senegalese striker for his fifth goal of the campaign.
Nghiem Chu Dinh’s side doubled their lead before the break, with Nguyen Quang Hai again instrumental, sliding the ball into the area for Ganiyu Oseni, with the Nigerian making no mistake from close range.
Just as Hanoi looked to be comfortably in control with 30 minutes to play, a momentary lapse proved costly as Naga's Kipson Atuheire broke quickly on the counter, playing the ball across the field for Kouch Dani, who cut the ball back for Anderson to expertly finish from the edge of the area, making amends for his miss in the first half on 63 minutes.
It proved to be a brief glimmer of hope for the home side as Hanoi restored their two goal advantage just seven minutes later when Tran Van Kien picked the pocket of Amir Gurbani on the edge of the area, firing home a rocket that gave Naga goalkeeper Sou Yaty little chance to react
The Vietnamese side put the match well and truly beyond doubt just before full time when Hoang Vu Samson bundled the ball home from a corner to make it 4-1, while a second goal for Oseni in stoppage time rounded out the deserved 5-1 win, making it back-to-back wins for the Vietnamese side.
Hanoi now face a must-win match at home against Tampines Rovers in two weeks to progress to the ASEAN Zonal semi-finals, while Naga World travel to Myanmar to take on Yangon United hoping to avoid finishing bottom of the group.
