Thailand are likely to change the line-up and tactics when they face Bahrain in their second game at the Asian Cup in the United Arab Emirates on Thursday.
After an embarrassing 4-1 loss to India in their opening Group A match on Sunday, the War Elephants now need a result against Bahrain in Dubai to keep alive their hopes of reaching the knockout stages.
Sunday's humiliating defeat led to Milovan Rajevac being fired as coach of Thailand.
Football Association of Thailand president Somyot Poompunmuang appointed Sirisak Yodyardthai to take charge of the team in the remaining games of the continental championship with Choketawee Promrut named as his assistant.
"The atmosphere in the team is still good," Choketawee said on Tuesday.
"Every player says he is ready to fight in the remaining games. We have to forget the previous game. The most important thing is we have to learn from our mistakes. During the first day of training [under Sirisak], the feedback from the players is very good."
Choketawee, who guided the Thai U23 team to the SEA Games gold medal in 2015, said he and Sirisak would make changes to the team.
"We will change our playing system. We are looking at players and considering who is suitable for which position," he said.
"We have to make the players understand our tactics. I am sure that if we are well-prepared, we still have a chance [to progress to the next round]."
He added: "I understand the Thai fans' feelings. We will try our best for the country and impress the fans."
After tomorrow's game against Bahrain, Thailand will play the UAE in their last group match on Monday.
The top two teams of six groups and four best third-placed sides advance to the next round.
Earlier, former Thai Honda coach Sirisak said he would try to steer the War Elephants to earn a point each against Bahrain and the UAE.
The two Middle East teams drew 1-1 in their first game.
In Thailand's six previous appearances in the Asian Cup, they got past the first round only once in 1972 when they finished third.
The Thais are playing in their first Asian Cup since their last in 2007 when they co-hosted the tournament.
Meanwhile, Somyot has not talked to reporters since he fired Rajevac on Monday as calls for his resignation has become louder.
