Petr Jiracek's second-half goal ensured the Czech Republic squeaked into the quarter-finals of Euro 2012 as co-hosts Poland suffered an early exit.
Outplayed for the majority of the first half, the Czechs were seemingly stung into action after Greece took a half-time lead against Russia in the other Group A game in Warsaw.
That result left Michal Bilek's men needing all three points to reach the last eight and after dominating the tempo after the interval, Jiracek's calm finish ensured they topped the group, with Russia and Poland the eliminated teams.
Poland knew nothing less than a win would see them reach the knockout stages at the expense of the Czech Republic, who also needed three points to guarantee their qualification for the last eight.
Similar to their previous two matches, Poland were understandably backed by boisterous home support and they nearly gave them something to shout about early on but Dariusz Dudka's overhead kick hit the side netting.
