Cristiano Ronaldo scored one and set up another as Portugal beat Czech Republic 3-1 to all but ensure their qualification for the quarter-finals of Euro 2008.

Deco who also scored and created another, putting Portugal ahead after eight minutes when he turned in a rebound after Petr Cech, the Czech goalkeeper, had saved from Ronaldo with his feet.

The lead was cancelled out nine minutes later when Libor Sionko scored from a diving header after a corner, but Deco set up Ronaldo for his second goal in the second half, who finished from near the penalty spot. Ronaldo then picked up a long ball from a free kick and crossed to substitute Ricardo Quaresma, who scored into an open goal.

Portugal have to play Switzerland in Basel on Sunday but, having beaten Turkey 2-0 on Saturday, are almost certain to make the last eight. They're hoping to go one better than their European Championship campaign of four years ago, when they finished as runners-up to Greece.
