Super Reds FC
Having finished last in the 2007 S-League season, Super Reds FC made several changes to their squad and Moon, along with his Incheon Korail team-mate Choi Young-Min, were signed up from the Korea National League side for the 2008 S-League season.
In 2009, Moon decided to move back to his native South Korea to join Korea National League side Cheonan City FC.
Cheonan City FC
With a knee injury hampering him during his time back in the Korea National League, Moon had little playing time at Cheonan. However, he managed to score 2 goals during his maiden season in 2009 despite spending most of his time on the sidelines. He was deployed mostly as a substitute. He finish his season with 2 goals in 6 appearance for the club. In his second season with Cheonan, Moon did make an impact by coming off the bench to score a stunner for Cheonan against Yongin City FC on 30 April 2010. His knack for scoring goals when coming on as a substitute earned him the title "super-sub".
At the end of the 2010 Korea National League season, despite scoring 3 goals in 10 appearances, Moon was released by the club as he struggled to recover from his injury.
Woodlands Wellington FC
Moon would soon return to the S.League when he was snapped up by Woodlands Wellington FC during the 2011 mid-season transfer window as a free agent. Joining him at the club was fellow Korean Hyun Jong-Woon, whom switched to the Rams from Tanjong Pagar United.
Moon proved to be a shrewd signing for Woodlands, as he scored 8 goals in the latter half of the season and finished the 2011 season as Woodlands' top scorer.
Moon kick-started the 2012 S-League season in great fashion, earning a penalty against the favoured Courts Young Lions and calmly slotting it home in the 48th minute, putting the Rams into the lead and ultimately winning the game for them.
Moon's telepathic understanding with Lebanese Australian attacking midfielder Hussein Akil has also been praised by football pundits, despite the pair only playing together at the start of the 2012 season.
In the 2013 S.League season, Moon finished as joint-top scorer in the S.League with 15 league goals and built up a telepathic relationship with fellow Korean striker Jang Jo-Yoon as the Rams stormed to a top-six finish. Moon's fantastic performances also earned him a spot in the inaugural Goal.com Singapore Football Awards' Team of the Year.
