The home team were off to a flying start as Shawal Anuar was hacked down in the box by Muangthong goalkeeper Kittipong Phuthawchueak within the first minute of the game.
Up stepped Lestienne to coolly tuck home from the spot and send his side ahead.
The Sailors continued to dominate play, with Lestienne pulling the strings in the middle of the park.
It would be the Belgian who played a delightful through ball to Shawal and the pacy forward passed the ball past the goalkeeper to a sliding Ramselaar in the dying embers of the first half.
Muangthong poured forward as they looked to unlock a stubborn Sailors defence.
But they found themselves 3-0 behind in the 63rd minute as the impressive Shawal lobbed the Muangthong goalkeeper after being played onside.
Aleksandar Rankovic’s men capped off a sensational performance as Shawal netted his second in the 88th minute.
