Portugal winger Cristiano Ronaldo may be fit to face Iran on Saturday after taking part in a training session.
Ronaldo is back in training
The 21-year-old trained separately on Thursday after complaining of aching muscles, but on Friday he took part in a one-hour session at the Waldstadion.
"In principle, from what I saw, he's got good possibilities to play against Iran,"said coach Luiz Felipe Scolari.
Ronaldo played in the opening game against Angola but was subsituted after 59 minutes of the 1-0 victory.
Scolari added: "Cristiano is not going through any difficulties apart from the usual ones of a 21-year-old who everyone expects great things from.
"He just has to play the way he usually plays, because that's the only way he's going to benefit.
"It's his first World Cup, it's the first time he's in the starting line-up at a major tournament, so it's all a bit different."
