Portugal striker Cristiano Ronaldo has said that he does not see any apprehension in his teammates as they prepare to kick off their Euro 2012 campaign.

Ronaldo and company enter the tournament on the back of a shock 3-1 defeat to Turkey in Lisbon, but the Real Madrid man insists that he and his team are fully prepared for the challenge ahead.

"I do not feel any anxiety and I do not see it in our players," he said. "Our team is fine and prepared.

"I hope that we will make a great campaign. We will go as far as possible."

Meanwhile, Portugal boss Paulo Bento has admitted that Nani could miss the team's opener.
