In the second half of the second leg of the Japan vs. Republic of Korea match in Yokohama, Yamaguchi laments the fact that his team has not yet won a single match. He feels that if they do not win, they will not have enough time to prepare for the upcoming World Cup in South America. He laments that he cannot imagine winning a single game to fill his head with confidence. In the heat of the moment, he says, he would like to watch his team's stamina carefully, but if it is like this, it will turn into a "shot-laden attacking game"
