Fulham midfielder Ben Davis says choosing to represent Thailand is the "best choice" for him.
"I have decided now. I spoke to my family about my citizenship. I have the options of Singapore, Thailand, Wales and England. Now, I have decided to choose Thailand," the 18-year-old told Thai TV channel True4U in an interview this week.
"I think this is the best choice for me. Thai football has a bright future and a chance to succeed. My parents also support my decision to the fullest."
Davis was born in Thailand and moved to Singapore at the age of five and played for the Singapore national teams at the youth level.
His mother Sopee is a Thai national, while his father Harvey is Welsh.
He is in the Thai squad which will play against the UAE in a World Cup qualifier next Tuesday.
The youngster is also in Thailand's initial squad which will defend the SEA Games title later this year. Both teams are coached by Japanese Akira Nishino.
In 2017, Davis became the first Singaporean to join an English Premier League club when he signed for Fulham who are now in the Championship (second tier).
Davis defaulted on his Singapore's national service earlier this year and his family made it clear they were ready to let go the Singaporean citizenship for the sake of the teenager's footballing career.
"At first, my dad wanted me to play for the Singapore national team, but that did not happen. Thailand has given me an opportunity. I will try to do my best to pay back," he told True4U.
Meanwhile, Thailand will play a warm-up match with Congo at Leo Stadium in Pathum Thani today.
Thailand lead Group G of Asia's qualifying round for the 2022 World Cup with four points from two matches.
The UAE, who have a game in hand, and Malaysia, both have three points. Vietnam have one point from one game while Indonesia are still looking for their first point after two losses.
Today, Vietnam host Malaysia while the UAE are at home to Indonesia.
