No doubt the best team won on the night. It would have been a travesty had Portugal not gone through after all the pressure and chances they created. Ronaldo was behind most things they did well in the final third and it is no surprise that he emerged as the matchwinner. The Czechs will reflect that they did not do themselves justice and could not reward their huge following with any meaningful chances.

The Czechs will have a huge advantage when it comes to support inside this very impressive stadium which is awash with red and white.
In a bid to be the longest distance comment, Irish Man Utd fan John Owens living in Vancouver says: "Nani to finally come out of his useless shell and give us a decent performance. To score in 90 mins at 4/1 is a bit tight though."

"Got to be Portugal 3-1 with Ronaldo 1st scorer or a great outside bet of Jiracek to score 1st but Portugal to win in 90 minutes. Looking forward to a great night!" says TC.

Good evening and welcome to our coverage of tonight's first quarter-final clash in Euro 2012 between Portugal and the Czech Republic in Warsaw. The Czechs reached the last eight as Group A winners, rebounding from an opening 4-1 defeat to Russia to beat Greece and co-hosts Poland, while Portugal go into the contest sky high after Sunday's 2-1 triumph over Holland which saw them progress from Group B as runners-up behind Germany. The Czechs go into the encounter as underdogs but boosted by the news that Arsenal midfielder Tomas Rosicky will feature having recovered from an Achilles tendon injury. Rosicky suffered the injury in his team's 2-1 triumph over Greece and missed the final group game against Poland last Saturday. Meanwhile, Portugal have no injury worries and are expected to field Nani and Cristiano Ronaldo in support of Helder Postiga up front. Ronaldo scored twice against Holland to increase his tally for Portugal to 34 goals. Team news will follow shortly and, as always, we welcome your thoughts on what should be a cracking encounter so send them to firstname.lastname@example.org and I'll publish the best ones.
