"I am here because I want to help my national team. If I am not ready, if I am not feeling well, I would be the first to tell the coach I do not want to play," the Portugal's talisman said in a pre-match conference at the Fonte Nova Arena in Salvador, Xinhua reported.

The 29-year-old forward ended his training session early Thursday and limped off the pitch with an ice bag on his knee. Reports speculated that the FIFA Player of the Year could be sidelined for Monday's match between Portugal and Germany.

"As the coach has said many times, the first thing he cares is the health of the players. If I feel anything, if I feel any injury which I am sure I was not feeling, I will be the first to say as I know my career will still last for a few years," Ronaldo said.

"I will never risk my career for one match or for the World Cup. It is the most important thing for me. It should be 'I' coming first and then football," he said.

Although Ronaldo labelled the suspicion as "something silly", he did admit he can still feel some pain right now.

"I have been practising for several days. That is because I have been feeling well. Obviously I would like to not have any pain, but that is impossible," he said.

"Since I started playing I do not have any day which I do not feel any pain or what so ever. This is just a part of it," he added.

Ronaldo insisted he is ready for a great World Cup and both his team and himself are highly motivated.

"What I want most is to be the same person in my club when in the national team, trying to give all my best for my team to win. And that is what I will try to do tomorrow (Monday) and the whole World Cup," he added.

Germany aim to reach World Cup final: Loew

Germany's priority is to reach the 2014 World Cup final and then think about winning the title, national coach Joachim Loew said.

Germany, the second-ranked team in the world, according to FIFA rankings, will face Portugal on Monday in their opening game this year.

"Portugal is a great team, but if we work well as a team and defend well, seizing the opportunities we create, we have great potential to go far," Loew said.

Germany, having won 12 of their 17 opening matches and lost only once, a 2-1 to Algeria loss in 1982, have the confidence to move on in this World Cup.

"We have quality and talent. In these last several days, during practice, I felt certain expectation and tension. Everyone is more excited, and we are ready for the World Cup," said Loew. Germany are in a tough group, with Ghana, US and Portugal.
