Lee Dong-gook scored twice as Jeonbuk Motors defeated nine-man Busan I'Park 3-1 to move to within a point of K-League leaders Seoul.

Seoul were due to play third-placed Pohang Steelers this weekend, but as the two clubs have Asian Champions League quarter-finals on Wednesday, the match was postponed. Jeonbuk took advantage of their rivals' inaction by taking the lead within seconds of the kick-off.

Busan defender Lee Kang-jin attempted to clear a corner, but succeeded only in volleying the ball into his own net from close range. Busan were back on level terms ten minutes before the break as Han Sang-woon broke through the Jeonbuk defence to slot the ball home from a tight angle.

Just before the half-time whistle, former Middlesbrough player Lee grabbed his 16th goal of the season, controlling a chipped pass just inside the area and coolly volleying the ball into the Busan net. Busan lost Seo Dong-won and Chu Sung-jin in the second half and Lee sealed the win ten minutes from the end when his shot was deflected into the net.

Jeonbuk coach Choi Kang-hee said: "I wasn't very satisfied with our performance. We made too many mistakes after we scored the opening goal.

"There are many games remaining and we will do our best to get three points whether we play at home or away."

Gyeongnam moved into fifth courtesy of a fifth straight win though they had to come from behind to defeat Gwangju Sangmu 2-1. Jang Hyun-kyu headed home a corner for Gwangju after 17 minutes and while Gyeongnam dominated the match, the hosts had to wait until just after the hour to equalise as Lee Yong-rae sent a header into the bottom corner.

With eight minutes remaining Indio clinched the win in style, driving home a fierce shot from just outside the area.

In the day's other match, bottom club Daegu recorded their second successive win by defeating Gangwon 2-1.
