At Real Madrid, I did heading drills with Cristiano Ronaldo. You see him go up for headers, that spring and power - he is a real beast. At Juventus, I saw Fernando Llorente, how he finds space and directs his headers.
To be able to earn what Cristiano earns, I would have had to have been the best player at the World Cup or won the Ballon d'Or.
I am aware of importance of the No.7 shirt. Cristiano Ronaldo had spoken to me at Real Madrid and told me how important it was.
Someone like Cristiano Ronaldo focuses on scoring to progress, so perhaps I need to think more about scoring.
I've been fortunate to play with many great players, including Cristiano Ronaldo for Portugal.
Of course Cristiano - what he has done over the last 15 years in football - is probably one of the best players ever in the history of football, so no comparison to him.
To play against Cristiano and Messi, it is always complicated.
They are among the three best in the world: Cristiano Ronaldo, Lionel Messi and Neymar are the three best players in the world and I'm happy I have one of them playing alongside me.
Speaking of Cristiano is very easy, we know that he's the best in the world.
What stands out for me are the chances that Cristiano has created and the desire to score that he always has.
