A last-minute goal from Ko Chang-Hyun saw Pohang Steelers' K-League title hopes all but ended after they lost 2-1 at Ulsan Horang-I.

Ko struck in the closing seconds just seven minutes after Derek Asamoah had seemingly snatched a point for the visitors. Go Sul-Gi had put Ulsan ahead after 20 minutes.

It's going to be hard for us to finish in first now.
Hwang Sun-Hong, Pohang Steelers coach

The defeat leaves Pohang six points behind leaders Jeonbuk Motors with two games to go, while Ulsan climb to sixth and into the final play-off berth for the first time this season.

"It's going to be hard for us to finish in first now," said Pohang coach Hwang Sun-Hong. "We just need to confirm second place for the play-offs in the remaining games we have. We didn't play badly, we tried our best."

Ulsan coach Kim Ho-Gon said: "It was an important win for us. Now we are in the top six, we will do all we can to stay there."
