Cristiano Ronaldo said he has overcome his injury and is fit to play with Portugal in the World Cup qualifiers on Saturday. Real Madrid missed Ronaldo in the 2-1 defeat against Sevilla. It was the first loss of the season as well as Ronaldo's first game on the sidelines. But the energetic winger said on Real Madrid's website: "I've recovered well. It's all been normal. I think I will be able to play on Saturday." Portugal face the danger of not qualifying to the 2010 World Cup. They are third in Group A on 13 points, two points behind second-placed Sweden and five adrift of leaders Denmark after eight games. But Ronaldo believes his side still can clinch their spot in South Africa. "These are decisive games we must win. Spirits are always high on the national team because this is an excellent squad," he said.
