Buriram United moved closer to retaining the Thai Premier League title after winning 3-1 at Si Sa Ket on Wednesday night.

The win, coupled with second-placed Chonburi's 1-0 loss at Army United, gave the Thunder Castle a four-point lead with five matches to go.
The vanishing spray was first used on Wednesday in the TPL which resumed after a one-month break for the Asian Games.
At Si Sa Ket Stadium, Buriram had few problems in their 3-1 victory against the Koupreys.
Spanish forward Carmelo Gonzalez, who returned from a seven-match suspension, opened the scoring for Buriram after just five munites only for Tatree Sreeha to equalise four minutes later.
Buriram dominated for long periods and Javier Patino scored twice to finish off Si Sa Ket.
At Army Stadium, the hosts went ahead after nine minutes through South Korean striker Hyun Jin Lee.
Chonburi then piled the pressure on the hosts but failed to find the back of the net.
