Ulsan maintained their 100 percent record with a 4-2 win against Pohang. Server Djeparov opened the scoring with his second goal of the season before Pohang equalised through Son Jun-ho. Masuda and Yang Dong-Hyun gave the visitors a three-one advantage. Tiago Alves scored to give Pohang fans hope of a comeback, but those hopes were extinguished to minutes later when Kim Shin-Wook opened his account for the season. Jeonbuk also managed two wins out of two with an easy victory against an uninspired Seoul. Edu opened the scoring in the second half with his third goal of the season before Eninho put the game to bed in the seventy-first minute. Kim Hyun-Sung scored a late goal for Seoul but Jeonbuk held on for a deserved win. Gwangju won the battle of the promoted clubs two-nil away at Daejeon. Incheon meanwhile dropped more points through late goals this week, with Yeom Ki-Hun scoring in injury time to give Suwon a two-one win, Seongnam v Jeonnam and Jeju v Busan both finished goalless.
