Despite two convincing wins on the trot,India will have to guard against complacency when they take on an Malaysia in the quarterfinal of the Champions Challenge on Thursday. Indian coach Michael Nobbs said the team would not show all the tactics it was working on even if that meant losing some ground in the knockout matches. The Champions Challenge offers a place to its winner in the Champions Trophy,but our focus has all along been the Olympic qualifier,and were not going to deviate from that, he said. In the quarterfinals,Pool B toppers Argentina will meet Poland,who suffered big defeats in all their three outings. Belgium will take on Canada in the round of eight,while hosts South Africa are pitted against Japan.
