The South Korean admitted that he wasn't only asked by the Indonesia Football Association (PSSI) to revolutionise the senior team, but also to improve the Under-23 and Under-20 teams.
Tae-yong rejected the advances of China club Shenzhen FC and not even the offers from several top J-League clubs could change his mind on the matter.
"I will go to Indonesia on December 26 to sign the contract. Nothing will change and that is finalised.
"I've been asked to improve all aspects of the national teams including the junior teams what with the World Cup U-20 being held in Indonesia," said Ta-yong in a Dong-A article.
