Thailand coach Rakphol Sainetngarm apologised to fans after his team failed to reach the quarter-finals at the Fifa Futsal World Cup in Lithuania on Thursday.
Thailand's bid for a first ever berth in the Futsal World Cup quarter-finals was dashed after being beaten by Kazakhstan 7-0.
Thursday's match was Thailand's third straight appearance in the last 16 round which remains their best result at the World Cup.
"I would like to apologise to all Thai fans. Everyone in the team was disappointed. We gave our all but the result was not what we had expected," Rakphol said.
His own future as Thailand coach remains unclear after he replaced Spanish Pulpis, who quit just weeks before Lithuania 2021.
Against world No.7 Kazakhstan, Thailand's dream was shattered in the opening minutes as they conceded two goals shortly after kick-off.
Dauren Tursagulov opening the scoring in the third minute and Douglas turned from provider to scorer a minute later.
Kazakhstan never looked back as six players were on target including goalkeeper Leo Higuita with the other coming from an own goal by Thailand's Chaiwat Jamgrajang.
World No.18 Thailand, to their credit, kept fighting but the likes of Suphawut Thuenklang, Jetsada Chudech, Kritsada Wongkaeo and Muhammad Osamanmusa failed to find the back of the net.
Suphawut Thuenklang said: "We did not start well and conceded two early goals. This forced us to change our game plan. We also made a lot of mistakes.
"We have to apologise to our fans. We worked very hard but failed to advance."
It was Thailand's sixth successive Futsal World Cup appearance, having reached the finals for the first time in 2000.
