FIFA 18: The duo with a Singaporean background
The 22-year-old midfielder currently plays for Wycombe Wanderers in the fourth tier of English football and has expressed a desire to play for the Lions in interviews with Singapore media.
O'Nien's Singaporean heritage can be traced back to his late grandfather Lim Cheng Siong, also the brother of former Singapore cabinet minister Lim Kim San.
Lim married an Englishwoman and their daughter is O'Nien's mother.
A trainee at Watford before being released in 2015, the energetic midfielder is now a first-team regular at Wycombe.
The central defender recently signed a one-year deal with Crewe Alexandra, also in the fourth tier of English football.
He scored his first goal for the club earlier this month in a 5-1 victory over Chesterfield, having signed professional terms back in May 2014
Although he holds a British passport, the central defender is eligible to play for Singapore thanks to his paternal grandfather.
“Yes, of course I’d love to play for Singapore,” Ng told FourFourTwo this year.
“The FAS (Football Association of Singapore) got in contact with me before but didn’t follow through.”
