Career
Chung Woon started playing football at Hakseong Elementary School, close to the Ulsan Hyundai Football Club, going on to the Hyundai Middle and High schools, before going to Myongji University in Seoul. He was drafted in the 2012 K League draft by Ulsan Hyundai as a 2008 secured player, officially having replaced at some point another player. His career at his hometown club only lasted during the 2012 season, being unable to secure a single first team cap.
He went to Croatia in early 2013 and passed a trial with the Prva HNL team NK Istra 1961 from Pula, signing a 2.5-year contract.
He quickly established himself as the first choice on the left back, but also made rare appearances on both wings and on centre back, and kept his position at the beginning of the 2013-2014 season. After two years at Istra 1961, Woon moved to RNK Split, along with his teemmate Slavko Blagojević, signing a three-and-a-half-year-long contract.
