Cristiano Ronaldo fired Portugal into the semi-finals of Euro 2012 after his diving header disposed of Czech Republic 1-0 in Warsaw.

The Real Madrid forward had twice hit the woodwork and seen his side have a goal chalked out for offside before he arrived on cue in the six-yard box to nod  in Joao Moutinho's cross on 79 minutes.

The Czechs - with captain Tomas Rosicky, the Arsenal midfielder, only on the  bench because of an Achilles injury - had started brightly, but lacked a  decisive move in the final third.
