Portugal should be proud of their performance at Euro 2012, even if their campaign ended in Wednesday's crushing defeat in a penalty shootout in the semi-finals to holders Spain, forwards Cristiano Ronaldo and Nani insisted.

"We didn't lack for conviction but we were unlucky. That's penalties for you," said Ronaldo, whose frustration was apparent after he did not even get to take his kick as Portugal's final penalty-taker, Cesc Fabregas had already wrapped things up at 4-2 to Spain, meaning there was no way back.
