Despite often being regarded as the best team in Southeast Asia, it has been ten years since the War Elephants last got their hands on the region's biggest prize.
Since being crowned champions in three of the first four editions, Thailand have had to endure two runners-up finishes in 2007 and 2008, as well as an embarassing group stage exit two years ago.
However, they moved one step closer to ending a decade of pain on Thursday after recording a 2-0 win over defending champions Malaysia to beat them 3-1 on aggregate in their semi-final clash.
Lying between them and the Suzuki Cup are Singapore and even though Schafer admits it won't be easy against Radojko Avramovic's side, he believes it is up to his players to put a smile back on the faces of the Thai fans.
"Singapore are a very good team," he said. "I watched them play in Philippines four weeks ago.
"But I think we too have a good team. It's not just our starting XI, all of our 22 players can play and do the job if called upon.
"We have a very good spirit and team work. The last time we won this competition was ten years ago - it is time we win it again.
"It won't be easy to beat Singapore but we want to win. We want a good result in Singapore and we want to make our fans happy again."
Thursday's victory over Harimau Malaya in Bangkok was arguably Thailand's best display all tournament long, and came just three days after they stuttered to a 1-1 draw in the first leg at the Bukit Jalil National Stadium.
Despite some of his players failing to deliver in that game, Schafer keep his faith by naming the same starting XI and was pleased with how they responded.
"We played the same 11 players as we did in Malaysia," the German added. "I trust my team.
"We had problems in the first half in Malaysia, but the second half performance was very good.
"Tonight [Thursday] you can see they [Malaysia] only had one chance late on with the header [from Norshahrul Idlan Talaha]."
The War Elephants boss also dismissed suggestions his side's cause was helped significantly by the first-half dismissal of Malaysia centre-back Fadhli Shas, who was handed a second yellow by referee Lee Min-hu after squaring up to Datsakorn Thonglao.
"Believe me, I do not know [if it was the right call]," Schafer said. "In the game in Malaysia, nobody asked why I had to go out [when I was sent off].
"But I do my job and prepare my team and it is not my job to say if the referee was right or wrong. We have a match commissioner and a referee's assessor for that.
"Maybe it changed the game, but we were the better team from the first minute. We played football and we didn't lose possession in midfield like Malaysia did."
Thailand are looking to win the Suzuki Cup for a record fourth time, but final opponents Singapore are also looking to achieve the same feat after their victories in 1998, 2004 and 2007.
