Czech Republic and Portugal were drawing 0-0 at half-time of their Euro 2012 quarter-final here on Thursday.
The opening 45 minutes were entertaining without really producing any great moments of anxiety for either goalkeeper.
Cristiano Ronaldo's back header from a Czech corner flashed over his own bar while impressive Czech fullback Theodor Gebre Selassie got down the right flank to deliver a dangerous low cross but Pepe was on hand to make a desperate clearance.
Up the other end Ronaldo flashed one long range freekick round the post and had an effort when one on one with Petr Cech blocked by the Chelsea goalkeeper, though, referee Howard Webb would have ruled it out had it gone in for an infringement.
The Portuguese lost striker Helder Postiga towards the end of the half to what looked like a hamstring injury.
However, it was they who finished the strongest with Ronaldo turning his marker and lashing a shot which beat Cech but came back off the post.
