Cristiano Ronaldo gets Portugal to the Semi-Final with a Stunning Header

Cristiano Ronaldo capped a magnificent display with the match-winning goal as Portugal powered past Czech Republic and into the semi-finals of Euro 2012.

Ronaldo, who scored twice against the Netherlands, hit the woodwork in each half with fine strikes.

And he finally found the net with 12 minutes remaining, thumping a header into the ground and beyond Petr Cech.

Czech Republic failed to muster a shot on target as they rarely threatened throughout a tense evening.

Portugal will now face Spain or France for a place in the final, and with arguably Europe's best player beginning to show his very best form, they could take some stopping.
