South Korea's coach wants a more clinical approach in today's match against Bahrain, where the team needs a victory to get their Asian Cup campaign back on track.
Bahrain, who lost their first Group D match with Indonesia, also need to pick up points against the 2002 World Cup semi-finalists. Another loss would see the Middle Eastern side knocked out.
"This for us is maybe the last chance," Bahrain coach Milan Macala told a press conference yesterday.
"We need to have a minimum of one point, but better to have three," he said.
South Korea drew their first match with fellow Asian powerhouse Saudi Arabia 1-1 in a tie that was disrupted for 25 minutes when the power failed inside the stadium late in the second half.
Team coach Pim Verbeek was happy with the performance against the three-time champions, but said his players should have put the match beyond the reach of Saudi Arabia when they were 1-0 up and in control of the game. Saudi Arabia equalized with a penalty.
"[On Sunday] they should not make mistakes, kill the game and win it," the Dutchman said. "I am looking forward, with a lot of confidence, to the game. We are going to do everything we can to win."
South Korea have underperformed on the international stage since the 2002 World Cup.
Amid high expectations of victory, they were beaten by Iran in the quarter-finals of the last Asian Cup in China in 2004. They have won the Asian Cup twice, but the last time was almost 50 years ago.
Verbeek has been unable to pick Manchester United midfielder Park Ji-sung and Tottenham Hotspur left-back Lee Young-pyo due to injuries, but has included Middlesbrough striker Lee Dong-gook in the squad.
Verbeek said Lee Chun-soo, an attacking midfield player who rose to prominence at the 2002 World Cup, had recovered from a fever that saw him miss the first match and was fit enough to start today.
