Buriram PEA claimed the domestic treble after overcoming Thai Port at the Supachalasai Stadium in Bangkok.
The downpour shortly before kickoff wasn't going to dampen Buriram's day although the sodden pitch did cause players of both sides to slip and slide making the game slightly farcical at times.
The opening goal came on 21 minutes when a left-footed inswinging free-kick from Rangsan curled into the top corner. It was probably meant as a cross but the quality of the delivery perhaps exposed the 178cm Thai Port keeper's lack of height as the ball sailed over him.
Thai Port fought hard for the 90 minutes but were unable to test Sivaruk in the Buriram goal.
With time running out, Buriram PEA sealed the contest deep into injury time. As Thai Port sent everyone upfield to press for an equalizer, Clarence Bintang broke from inside his own half and coolly trundled the ball into the vacant net from about 45 yards out.
Buriram weren't at their best today but they seemed to have that bit extra in their locker. It was a deserved win for the Thunder Castle and they'll be back at the Supachalasai in 2 weeks to face the Japanese side, Vegalta Sendai, in the Toyota Premier Cup.
It was a brave effort from the Khlong Toei side, but with lack of striking options it was always going to be a tough call to overcome PEA. The young lad Sarawut ran his socks off but he was plowing a lone furrow upfront for most of the game. The newly named Port FC now have to focus on next season and start finding replacements for the departing members from the squad. For me, the priority is to improve the spine of the team. A powerful leader at centre half is needed, a creative midfielder in the centre of the park, and a striker that will bag at least 15 goals a season. It should be an eventful 6 weeks at the PAT as Port FC prepare for their season opener yet again at Chonburi.
