Ivan Klasnic fired the game's only goal for Croatia as Poland's unlikely bid to reach the last eight ended in failure.

Needing to beat Croatia by at least two goals, and for Germany to lose to Austria, only a string of Artur Boruc saves kept Poland's losing margin down.

Danijel Pranjic, Ivan Rakitic and Klasnic had all been denied before the latter lashed in the winner left-footed from 12 yards early in the second half.

Ebi Smolarek wasted late Poland chances but Group B winners Croatia held firm.
