Saturday's charity match between the TPL champions Buriram and runners-up Muang Thong serves as a traditional curtain-raiser for the new season of the Thailand Premier League, which will begin later this month.
The King's Trophy is the country's oldest football match and this year's will be the 98th edition.
Buriram's Thanasak Srisai and Adisak Kraisorn are both injured and will not feature in the match but team manager Tadthep Pitakpoolsin said he is not worried.
"Buriram United are ready for the match. There are two injured players but that is not the problem because we have other players that can replace them. We are confident that we can bring the title back to our home soil," he said.
Although Buriram changed coach in the later stage of the previous season, the players managed to sweep all domestic titles - the TPL, FA Cup and League Cup.
Tadthep believes the work by Spanish coach Alejandro Menendez Garcia during the pre-season will help them maintain their good record against Muang Thong.
Buriram have not lost to Muang Thong in their last 11 meetings.
Meanwhile, Kirins director Ronnarit Suewaja said: "It is an honour for our team to play in the King's Trophy match. Although we have a poor record against Buriram United.
"That was the past and this year we will try to beat them and win the trophy.
"During the pre-season, new coach Scott Cooper has had time to get to know the players and they are now familiar with his tactics after several warm-up matches.
"We are now ready for the match and our goal is to win the King's Trophy match for the second time."
Cooper was appointed as Kirins coach last month.
Tickets for the match are on sale at the Thai Ticket Major outlets at prices of 100, 200 and 300 baht. Proceeds from the match will be donated to the King's charity projects. The match, which takes place at Suphan Buri stadium, kicks off at 5.30pm. Channel 9 will broadcast the match live.
