Japan coach Takeshi Okada has conceded that he may quit after his team's exit from the tournament at the hands of Paraguay, 5-3 on penalties.
Okada's side had hopes of reaching the quarter-finals for the first time but, after a very defensive display at the Loftus Versfeld stadium in Pretoria, they succumbed to the Paraguayans after a dire goalless draw.
"I don't think I have anything left to do now," Okada told a news conference. "It's my responsibility, we did not insist enough. I cannot elaborate any further. When I look back at what I could have done for the players and what I did as a head coach I should have been more insistent on winning."
When accused of playing excessively defensive tactics and like-for-like substitutions, Okada replied: "All substitutions and changes I made were to try to push. It's difficult to narrow down why we couldn't score. We are not a team that can score lots of goals."
