Two hours of football ended goalless at Suwon World Cup Stadium before the Bluewings held their nerve to win the shootout 4-2 against the league leaders.

Marcio missed his spot kick for the hosts though both Kim Eun-jung and Neko did the same for Jeju.

Busan squeezed into the final with a 3-2 win over Chunnam Dragons that came in extra time.

Chunnam went ahead after 33 minutes thanks to Brazilian star Indio but five minutes later Yoo Ho-joon levelled and the scores remained the same after 90 minutes to send the game to extra time.

Han Sang-woon put Busan ahead in the 94th minute but 10 minutes later Adrian Chuva made it 2-2.

Han Ji-ho grabbed the winner after 110 minutes of play.
