The former FC Seoul playmaker told www.celticfc.net: "I am absolutely delighted to sign for Celtic, a football club with a tremendous history and one which is known throughout the world.

"I know that Celtic has some of the best supporters in the world and I will be doing all I can to show these fans what I can do and give everything as part of a team which will aim to achieve more and more success.

"When I lived in Australia, my football coach there was a Celtic supporter and through him I really became interested in the club.

"It is now a dream come true for me to join this great club - already, Celtic has shown me a tremendous welcome and I really do now feel part of the Celtic family.
