A header by Cristiano Ronaldo gave Portugal a place in the semi-finals after they beat Czech Republic 1-0 on Thursday in their quarter-final.
Ronaldo - who scored a double in the 2-1 win over the Dutch in the final group game - got the winner in the 79th minute in a game where but for Czech goalkeeper Petr Cech and the post - which he hit on two occasions - he could have had a hatful.
He goes joint-top of the scoring charts with three.
The Czechs didn't have a chance on target hindered by the absence of injured playmaker Tomas Rosicky.
Portugal will play either defending champions Spain or France in the semi-finals.
