Stand-in 'keeper gives Koreans reason to believe

Second-choice goalkeeper Jo Hyeon Woo was South Korea's hero as they beat Saudi Arabia 4-2 on penalties to set up an Asian Cup quarter-final with Australia.

Jo stepped up when regular No 1 Kim Seung Gyu was injured in training and proved he was up to the job after a nail-biting last-16 match in Doha ended 1-1.

Jo said "belief" was the key to stopping spot-kicks from Sami Al-Najei and Abdulrahman Ghareeb before Hwang Hee Chan converted the decisive penalty for Jurgen Klinsmann's side.

South Korea came back from the dead to keep their hopes of winning the cup for the first time in 64 years alive. Cho Gue Sung scored a 99th-minute equalizer to force extra time after substitute Abdullah Radif had opened the scoring for the Saudis.

Saudi coach Roberto Mancini disappeared down the tunnel before Hwang took the final penalty. He later apologized, saying: "I thought it was finished."
