Thailand beat Japan 3-0 in the Asian Championship final in Nakhon Ratchasima on Saturday to win their second continental title.
Thailand will play at the World Grand Champions Cup in Japan in November as Asian champions. They will then take part in the SEA Games in Myanmar in December.
They will have a busy schedule next year, as they are eligible to play at the World Championship, World Grand Prix, Asian Games and AVC Cup (Asian Cup).
"We need two teams with about 30 players because we will have to play in several tournaments," said Charnrit Wongprasert, a senior official at the Volleyball Association of Thailand (VAT).
"We should draft in more young players. Some of them are good but have not yet been given chances to play for the national team."
As for the World Grand Champions Cup, Charnrit said all first-team players will be in the squad and some young players will be in the team to gain experience.
As for the SEA Games, Charnrit said the VAT will use the first team because the second-string side may not be good enough to beat Vietnam.
He called on the government to give the association more support.
"We have been successful mainly because of support from the private sector. But we still need more support from the government," Charnrit said.
"We may get financial support after our success but what we need is support for long-term development."
Following their success in Nakhon Ratchasima, the team received nearly seven million baht in financial rewards from its sponsors, including Thai Beverage Marketing (one million baht) and AIS (1.5 million baht).
Thailand head coach Kiattipong Radchatakriengkrai said the VAT has the plans and human resources to create a strong second national team.
"But we need time and money," said Kiattipong, who also guided Thailand to their first ever Asian title in 2009.
Meanwhile, the players will give HRH Princess Maha Chakri Sirindhorn their Asian Championship gold medals, according to VAT president Somporn Chaibangyang.
The team will meet Prime Minister Yingluck Shinawatra on Friday.
