Warsaw: The Czech Republic failed to turn back the clock and repeat their 1996 glory Thursday night when Cristiano Ronaldo inspired Portugal to a convincing 1-0 quarterfinal victory at the European Championship here.

Portugal nearly broke the deadlock just before the halftime whistle when Ronaldo showed adapt footwork to control Raul Meireles' pass and struck low from the right area, only seeing the ball hit the post.

Ronald's effort was rejected by the post again five minutes into the second half when the forward's 23-metre freekick swerved over the wall and Cech's touch but hit the outside of the right post, which was Portugal's sixth time hit to the woodwork this tournament, creating a Euro record.

With 21 minutes left, Ronaldo finally made the breakthrough. The Real Madrid winger made an in-time run onto Joao Moutinho's right-flank pass to head into the dead corner in front a desperate Cech.
