Celtic tried to sign Oh Hyeon-gyu in the summer, according to Suwon Samsung Bluewings manager Lee Byung-keun, who reckons his former star player will be a hero in Glasgow.
The Hoops completed the signing of the 21-year-old South Korean international this week and boss Ange Postecoglou admitted he had tracked Oh for a while.
And his former club in his homeland have revealed the Scottish champions first made their move in the summer, before his World Cup heartache, where he missed out on their squad for Qatar.
