Cristiano Ronaldo is expected to be fit to play in Portugal's Group D clash against Iran on Saturday despite failing to complete training on Wednesday.

The Manchester United winger returned to the team hotel after the warm-up, fuelling speculation he suffered a hamstring injury during Portugal's World Cup opener against Angola.

However, team officials insisted Ronaldo is not injured and instead blamed his early exit from the session on the 21-year-old feeling "a little bit tired".

Meanwhile, Barcelona midfielder Deco returned to full training on Wednesday after recovering from the foot injury that prevented him playing in the 1-0 win against Angola.
