Besides being one of the greatest youth boxers in Southeast Asia, he was also a soccer prodigy.
He was going to play for the Thailand national team until he broke his ankle in a game and never could fully recover, but he did manage to become a very good table tennis player in the meantime. He was the top ranked youth player in Thailand for 2 years in a row.
