Portugal coach Fernando Santos has insisted that he is not worried about Cristiano Ronaldo's fitness ahead of Euro 2016.
The three-time Ballon d'Or winner recently missed three games for Real Madrid because of a hamstring injury.
Ronaldo was left out of last week's goalless draw with Manchester City in the first leg of their Champions League semi-final.
However, the 31-year-old could return to the pitch for the second leg at the Bernabeu after returning to training over the weekend.
"I was worried when I saw him complain against Villarreal and then leave the pitch," Santos told Lusa. "But we have already been in touch about his situation and it is nothing alarming. I think things will work out just fine."
Portugal's first group game at Euro 2016 is against Iceland on June 14.
