Gamba Osaka suffered their first defeat in Group H in the Asian Champions League on Wednesday night as the 2008 champions were smashed 4-1 at home by South Korea's Jeju United.
An own goal from Gamba captain Yasuhito Endo gifted Jeju the lead after 43 minutes at Suita Stadium and Lee Chang-min struck the second on the stroke of halftime. Marcelo Toscano added a third early in the second period before man of the match Lee completed his brace with a sensational fourth 18 minutes from time.
Ademilson converted a late penalty for Gamba but it proved scant consolation.
