Cristiano Ronaldo is available for selection as Portugal prepare to begin their World Cup campaign against Germany on Monday. Ronaldo has suffered from knee and thigh injuries, but said: "I'm at 100%. I want to have a great World Cup."
The 29-year-old dismissed suggestions he must excel in Brazil to cap a career that has not reached the heights on the international stage.
"I don't think I have to show anyone anything," he said.
"If we look at my statistics and resume you'll see that."
"I don't have to demonstrate anything," argued Ronaldo, who recently scored 11 goals in seven internationals.
"Not now or before or after. What I have to do is continue my career which has been great so far.
"I believe one player is not a team, I'm here in the national team to help, I'm an additional player, I can make a difference in some of the games, but I can't carry the whole team on my back.
"I'm just someone who wants to help to become a champion. We're not the favourite or in the group of favourites, which is something which is good for us."
Ronaldo took a full part in the 15 minutes of Portugal's training session that was open to the media inside Arena Fonte Nova. "I've been practising now for some days and if I'm doing that it's because I'm feeling well," he added. "Obviously I would like to not have any pain but that's impossible.
"Since I've played football there's not been one single moment when I played a match without any pain whatsoever. That's just part of it, it's the burden of my work.
"If I'm not ready, if I'm not feeling well, I'm the first to tell the coach I can't play.
"The first thing that is important is the health of the players. If I feel anything during the match, which I'm sure I won't, I'll be the first to say, as I know my career will still last a few years and I'm never going to put at risk my career for one match or for the World Cup.
"Obviously this is one of the most important championships but I come first, and then football."
