Portugal winger Simao is not certain to start in their opening World Cup game against Ivory Coast, even though he has declared himself fully fit.
The Atletico Madrid wide man was expected to be first choice on the left hand side of midfield for the Group G match on Wednesday following Manchester United winger Nani's withdrawal from the squad through injury.
But the 30-year-old has been suffering from exhaustion after a long season with the Rojiblancos, having reached the final of the Europa League and the Spanish Cup.
It is presumed that coach Carlos Queiroz will go with Zenit St Petersburg midfielder Danny in the wide left role, with Cristiano Ronaldo taking his place on the other flank.
Simao insisted though that he was fit enough to start should he be called upon by Quieroz, and was ready and raring to go.
"Despite the fact there was a lot of debate on whether it would be me or Nani playing, right now there are 23 of us here and there is no guarantee that I will start as I don't own a place on the wing, we have many players who can play there," he said.
"I've finally recovered. At the moment I am at 100 per cent and it's been some time since the last game. Which was the Spanish Cup final.
"We've been working well and I feel good physically and psychologically."
