Buriram United continue their chase for a treble today when they meet PT Prachuap in the League Cup semi-final at Chonburi Stadium.
In the other last-four match, BG Pathum United take on Ratchaburi at PAT Stadium.
Buriram are looking forward to making a clean sweep of the Thai League 1, FA Cup and League Cup titles for a second season in a row.
They defeated Port in the FA Cup semi-final last week and will face Bangkok United in the final.
At the weekend, the Thunder Castle retained the Thai League 1 crown with three games to spare after a 2-1 win at Chiang Rai United, thanks to goals from Goran Causic and Pansa Hemviboon.
Buriram will be heavy favourites against the Killer Wasps, who are fighting to stay up in the top flight.
But coach Buriram coach Masatada Ishii warned his men against complacency.
"We are happy to win the Thai League 1 title," said Ishii.
"Our target is to win all three domestic trophies.
"Although Prachuap are struggling in the league, we cannot underestimate them. This is a knockout match, so anything can happen. We will field our strongest side."
Prachuap coach Dusit Chalermsan said: "We have nothing to lose. We are the underdogs but we will fight and hope to surprise them."
The other semi-final could be a close contest with Ratchaburi, who are sixth in the league, taking on eighth-ranked Pathum.
