Manchester United winger Cristiano Ronaldo is hoping to move a step closer to his dream of being one of the best players in the world this summer.
The 21-year-old has emerged as a key man for Portugal over the past three years and is expected to make a dramatic impact on the biggest stage of all in Germany.
He said: 'I'm trying to give my very best in every training session in order to be at my best level in the World Cup.
'I'm still not 100% but I will get there in time to help my team achieve its aims.
'My dream is to be one of the best players in the world.
'There are many players who can hope to be the best player in the tournament and I just hope to be among that group.'
After three seasons playing in the Premiership, much is expected from Ronaldo and he knows he must deliver.
'I want to prove my value,' he said. 'But I don't think the pressure will affect me.
'I know that there is great expectation and that really gives me motivation to improve.'
Ronaldo, who left Portugal at the age of 18 to join United from Sporting Lisbon, believes the experience gained from playing abroad has helped him mature.
'I left Portugal when I was young and I think I have done a good job abroad,' he said.
'I know that I am an example to children and I hope I can continue to be so until the end of my career.'
Portugal begin their World Cup adventure on June 11 against Angola in Hannover, before taking on Iran and Mexico in Group D.
