After the completion of round three, Seoul join Suwon Samsung Bluewings and Ulsan Hyundai Horang-I on seven points.

The situation was looking bad after 32 minutes at Seoul World Cup Stadium as Enio Olivera Junior fired home his first goal for Daegu after taking advantage of a defensive mistake.

Just two minutes later, however, the hosts were back on level terms as Kim Eun-jung headed home a loose ball in the area.

Following the equaliser, Seoul never looked back and 12 minutes into the second half they were ahead.

Daegu goalkeeper Baek Min-cheol brought down Kim inside the area and Dejan Demjanovic fired home from the spot for his second goal of the season.

And with 11 minutes remaining Koh Myong-jin sealed the win and a vital three points for Seoul.

"We made many mistakes in the first half," said Seoul's Turkish boss Senol Gunes.

"However we were much better in the second and recovered well. When we play at home, we are always looking to attack and win.

"We looked good today at times but we are still not yet at our best."

The Bluewings defeated Gyeongnam FC 3-0.

Ahn Hyo-yeon and Shin Yong-rok scored twice in the first half to put the two-time Asian champions in control and Seo Dong-hyun added a third in injury time.

Busan I Park drew 0-0 with Gwangju Sangmu.
