BBCU completed the double over Singh Tarua with a 3-2 win at the Royal Thai Army Stadium. Similar to the first match between the pair back in April, it was Bouba Abbo who was the difference between the sides.
Singh Tarua had the better of the early exchanges, but it was the home side that took the lead in the 15th minute. Singh Tarua's right back, Samart, allowed Kittiphop to cut inside onto his right foot, and the pint sized winger then unleashed a rasping shot past Watchara at his near post.
The visitors levelled midway through the half when Ivan Petrovic played in Leandro and the Brazilians flick with the outside of his boot beat Pomchai.
Tarua were certainly in the ascendancy in the opening period, and after the goal Leandro had a free kick and a lobbed effort that went close while Pomchai had to get of his line quickly to block an advancing Ali Diarra.
The tide turned minutes after the interval when Boonyarit's cross from the right found the head of Bouba Abbo to make it 2-1 to the hosts.
After the goal, the Big Bang enjoyed their best period of the game with Watchara doing just enough to smother Kim Woo Chul's shot while Pichit squandered a good opportunity as his close range downward header bounced up and over the bar.
The decisive goal came 20 minutes from time after slack defending from Tarua allowed Abbo to be slipped in down the right hand side of the box. The former Buriram man produced a neat piece of trickery before slotting past Watchara.
Within three minutes, Leandro gave Singh Tarua hope when he fired a free kick home to reduce the deficit
However, BBCU were to hold out as they whittled the clock down with some stubborn defending and the inevitable calls for treatment of supposedly injured players.
Singh Tarua didn't play too badly and they just need to write this loss off and move on. Air Force's handsome victory over Bangkok FC leaves them still in the promotion places despite the loss. BBCU are too far off the promotion picture and are just playing for pride. Their striker Abbo has always impressed me and I just wonder why he's playing for such an average side.
