Highlights - Portugal 7-0 North Korea
North Korea coach Kim Jong Hun blamed himself for his side's 7-0 defeat by World Cup Group G rivals Portugal.
The Koreans will bow out of the tournament following Friday's final group game against Ivory Coast, having lost their opening two matches.
"Our players, I think, played to their full potential but tactically speaking it fell apart," Kim said.
"We couldn't block the attacks, that's why they scored so many. It's my fault for not playing the right strategy."
He added: "As they game went on, Portugal became more aggressive and after we conceded the first goal, the desire and wish to equalise led to my team's collapse."
Kim was adamant his country would remain fully supportive of the side's efforts, despite the drubbing in Cape Town that ensured their elimination from knock-out contention.
"Back home, I believe that they will look at our next game and they will be rooting for us to play well," he said.
"They will be encouraging us I believe. Though we will not be able to reach our objectives, we have one game left and we will reinforce our mental abilities and prepare well for that match."
Coach Kim hinted that he may alter his team tactics for the final match against the African side.
"In the final match against Ivory Coast we will have to think over our strategy and tactics that will give us the best result there," he said.
