Round 4 of Thai League 2016 saw BEC Tero Sasana who struggled to survive last season upset the odds by beating league leaders Muangthong United 1-0 right at SCG Stadium.
The clash had been highly anticipated as the in-form Qilins captured a number of BEC Tero first team players ahead of 2016 season.
The visitors, however, proved they were no easy opponent with an unlikely win thanks to the only goal from Sivakorn Tiatrakul, who was interestingly a former Muangthong player.
Despite the defeat, Muangthong remain at the top of table with 9 points as Ratchaburi suffered the second loss and Buriram were busy with ACL schedule.
