Poland coach Pawel Janas believes Wednesday's clash with Germany is a do-or-die encounter and defeat will see them on their way home. The Poles were disappointing in their opening Group A clash with Ecuador and were sent packing 2-0 by the South Americans. Defeat against neighbours Germany will almost certainly mean that Janas' men will be out of the tournament but they will have their work cut out to beat a German side who put four goals past Costa Rica in the opening goal of the competition.This match is very, very important," he said. "If we don't get three points or even one, we can pack our bags and go home. "The match with Germany is the match of our life. It's a question of 'to be or not to be'."
