JacekKrzynowek then had a couple of efforts from long range as Poland gathered momentum, which continued after the interval as well, with Smolarek having a 20-meter shot saved.
But it was Poland who broke away again for JacekKrzynowek to drill in a left-wing cross that a stretching Lukasz Gargula just failed to connect with at the far post.
With Germany also taking an early second-half lead in Vienna, Klasnic's strike all but signalled the end of Poland's slim qualification hopes but they continued to battle and the hard-working JacekKrzynowek fired in an effort that went wide of the far post.
