Manchester United winger Nani insists Portugal leave Euro2012 with their heads held high.

Portugal lost their semifinal clash with Spain on penalties.

"We really gave it all we had, and it's difficult to go out on penalties," Nani said.

"We showed a lot of quality. In the end Spain simply had more luck than we did. But people in Portugal can be proud of their team. We are sad as we deserved to be in the final - but we can go home with our heads held high."
