Osmar scored a second-half winner as Seoul recovered from a woeful early defensive error to win 2-1 at Pohang Steelers in K League 1.

Seoul was this week hit with a 100million won (£66,000) fine after it mistakenly used sex dolls to fill spaces in its empty stadium during a 1-0 victory over Gwangju.

Matters on the field took a turn for the worse in the fifth minute of Friday's clash after a mix-up between Kim Nam-chun and goalkeeper Yu Sang-hun allowed Stanislav Iljutcenko to steal in and latch on to a backpass, gratefully tapping into an empty net.

Half an hour later Seoul was level as Hwang Hyun-soo glanced Park Chu-young's set-piece into the bottom-right corner.

Osmar struck the decisive blow in the 73rd minute, racing on to Ju Se-jong's corner at the near post to find the net with a powerful header.

The win moves Seoul on to six points, level with leaders Ulsan Hyundai and Jeonbuk Motors having played a game more. Pohang has four points from its opening three matches.
