Collapse of lines

So, Japan downplayed South Korea with its 3-0 victory. South Korean manager Cho Kwang-rae has described the loss as an “important lesson”. But this loss also raised up many questions about Cho Kwang-rae's tenure with the National Team. It was a friendly match, but a special one. And it ended with the biggest defeat to Japan since Korea lost 4-1 in 1974. The Japanese showed to be too much strong. Cho's attacking trio simply dind't work. Monaco's forward, Park Chu-young, had not support by Gamba Osaka's Lee Keun-ho and VfL Wolfsburg's Koo Ja-cheol. The absences of injuried Lee Chung-Yong; of Ji Dong-Won, remained in England with Sunderland; and of Hamburg forward Son Heung-Min, were too much for Korean side. Koreans best chance to score happened just on the 75th minute, when midfielder Koo Ja-Cheol missed a great opportunity to mark a consolation goal. "Should the front-line offense have done their job, we could have had a good result,” Cho said. But truth is that the players up front never had clear scoring chances. Midfield, with Ki Sung-yeung and Co., was a mess. On the flanks, japanese players have done that they want. Cha Du-ri showed his defensive lacks. Problem is also that among Korean media the key point for the loss was identified in the absence of veterans Park Ji-Sung and Lee Young-Pyo. The performance against Samurai Blue  was disappointing but there are doubts that Park and Lee could have made a difference. Cho has to try to insist on players such as Lee Keun-ho or Kim Bo-kyoung, eight goals in the J-League until now. On the left, full-back Kim Yong-Chol went out early so you can't judge him. A poor showing can't destroy soon all the work. Despite some adjustments to do (i.e. on defence), this is a long-term work. And instead that those come backs, a better perspective could be to throw young men into the international scene. You can try some experiments. The 2014 WC qualifiers, with South Korea alongside Kuwait, Lebanon and the United Arab Emirate, will be probably less tougher that this Japan match.
