Cristiano Ronaldo capped a dominant display with the match-winning goal as Portugal powered past Czech Republic in a well-deserved win that sent them into the semi-finals of Euro 2012.Ronaldo, who scored twice against the Netherlands, hit the woodwork in each half with fine strikes. He finally found the net with 11 minutes remaining, thumping a header into the ground and beyond Petr Cech.It was unfortunate for the Czechs that Ronaldo would play such a central NFL Los Angeles Rams Jersey figure in their defeat as they appeared to have done a good job of stifling him in the early stages.Although Czech Republic failed to muster a shot on target as they rarely threatened throughout a tense evening.Ahead of the game Czech Republic made one change from the team that beat Poland 1-0, with Valdmir Darida in for Daniel Kolar. Kolar had been playing the Thomas Rosicky role after the Arsenal midfielder picked up an Achilles injury. Portugal on the other hand had a fully fit squad and named an unchanged squad for the fourth consecutive game.Portugal made a very slow start to the game with the Czechs getting a string of corners but not quite picking out the right delivery. Any time Portugal did attack the Czechs were quick to close them down, they had clearly done their homework.Portugal did begin to wake up in the 12th minute when Nani moved to the left-hand side and combined with Contreao, pawing at the Czech defence until there was an opening. Some neat skill on the ball from Contreao briefly opened up some space, although his cro s hit a man in red. Nani then set Moutinho up for a long-range shot that Petr Cech saved comfortably, that was the first thing either keeper had to do. Cech was again called upon in the 24th minute when Coentrao almost caught him out with a deflected cro s from the left that looped towards goal but the Czech keeper backtracked to claim.Suddenly Ronaldo sprung to life Marshall Faulk Jersey as he sprinted into the box to receive a pa s from Moutinho and muscled Michal Kadlec off the ball. His shot was goalbound but palmed away although the ref, Howard Webb, deemed to challenge on Kadlec to be a foul so it wouldnt have counted anyway. However the Czechs looked just as dangerous when Theodor Gebre Sela sie cut down the right and cro sed low, but Pepe averted the danger.Portugal raced back up the other end but Coentraos cro s was deflected up and on to the top of the Czechs goal. Ronaldo then produced an acrobatic overhead effort from a Pepe poked ball but it flew woefully wide of the goal.No one was getting close at goal and even a Ronaldo free-kick from 30 yards flew low past the far post. The Seleco were forced to make a change on 39 minutes when Helder Postiga hit the turf clutching his thigh after starting a sprint. The striker was stretched off and replaced with Hugo Almedia.Chances in the match were at a premium, unfortunately so were periods of prolonged po se sion from either side. Countle s errors, misplaced pa ses and the like made the game not very pretty to watch.Portugal stole all the limelight in the final minutes of the half first when Nani drooped to the turf in the penalty area leaving the Seleco screaming for a penalty, then Ronaldo had the best chance of the match. Pulling down Raul Meireles long ball in the box with his chest he then flicked the ball pa s Michal Kadlec before it hit the turf to give him sight Ben Skowronek Jersey of goal. His shot from 10 yards beat Cech but smashed into the post.HALF-TIME: CZECH REPUBLIC 0-0 PORTUGALAfter the tightest first half youd ever see the first chance of the second came just 30 seconds after the break. Raul Meireles cro s found Hugo Almeida totally unmarked 12 yards out, but he planted his header over the bar and behind. Portugal were on top two minutes later as Ronaldo had another long-range free-kick which was brought forward 10 yards after the original delivery was handled by a Czech defender. His second effort bet the wall and Cech only for the post to again deny him. Portugal had come out meaning busine s leaving the Czechs with their hearts in their mouth.The Czechs were out in body but not in mind as they were struggling to have a constructive kick. Meireles launched another Portugal attack with a lofted pa s to Ronaldo who scampered into the box and opted to shoot early though he sliced his effort and it flew wide of goal. Ronaldo then had another effort for Portugal, this time frim distance, but it deflected wide for a corner. The delivery was fired in by Meireles but over the bar.Ronaldo was seeing more of the ball but then so were most Portugal players. It was Nanis chance to have a shot next from 25 yards which Cech superbly palmed away. It wouldnt be surprising to hear that Portugal had the ball in the back of the net on the 60th minute as Hugo Almeida dived low to head into the net from a Nani cro s but the flag was raised and the goal rightly ruled out.It had taken 17 minutes but the Czechs finally had their first attack of the half and quite a decisive one it was. A superb run from Vaclav Pilar beat three men en route to the edge of the Portugal box on the left, however his final cro s was poorly delivered, like so many before. The Czechs responded by Jake Funk Jersey bringing on Jan Rezek for Vladimir Darida and the chance worked as they had a decent little spell but again it was their finishing that let them down.Portugal retained the momentum as Moutinho rifled a shot from 20 yards only to be denied by a tip-over from Cech Ronaldo followed up with another chance as he skipped in front Kadlec at the near post and tried to flick a shot at goal which went just wide. Next Ronaldo turned provider for Portugal by controlling a ball back for Meireles who had a chance to test Cech but blazed his shot well over the target.At this point of the game, with the match being so tight, a goal for either team would all but guarantee a win and Portugal looked the most likely to get it as they came close again. Meireles strode towards the Czech box and poked a ball through for Nani whose shot is looped up and over the bar by a well-placed Kadlec. That was followed by more wastefulne s by Nanias he played a one-two to get in behind the Czech defence on the right but planted his low cro s straight into the arms of Cech.With all those mo sed chances the Seleco could be forgiven for giving up hope but luckily they did finally find the bag of the net on 79 minutes. It had been coming all game and it was no real surprise who scored it. Moutinho Grant Haley Jersey swung over a great cro s from the right which was too high for Almeida but not forRONALDO who muscled his way on to a header that planted into the ground and up into the net past Cech.The ball was now firmly in Portugals court as they rushed forward again looking to end the game. Perira fired a shot on goal from just inside the area but Cech palmed away. Portugals solution was to bring Custodio on for Nani and Rolando on for Meireles as they attemp
