National Under-17 captain Nelson Maluleke said the players have learnt valuable lessons from Monday's 2-1 defeat to Costa Rica ahead of their do-or-die World Cup group E match against Korea DPR today. This is probably Amajimbos' best chance of collecting three points in the group against a country that has very little history of competing.The Asians participated in the competition in 2011 and were knocked out in the group stages after they drew two matches and lost one.On Monday they were beaten 2-0 by current group E leaders Russia, who play Amajimbos on Sunday.Said Maluleke: "We did not win and it hurts, but that's part of the game. Now we are looking forward to our next match. It's a must win for us because if we lose the game it will be over."Maluleke will have to rediscover the form that inspired Amajimbos to the final of the African Under-17 Championship in Niger earlier this year.He won three man-of-the-match awards in the team's five matches and was named in the team of the tournament.Ahead of the match, coach Molefi Ntseki said: "Firstly, we need to give ourselves a chance. Despite the result in our first match we should stay positive."We really need to collect three points."..
