"To score 40 goals is an unbelievable achievement - I wished I could have guessed it at the start of the season," Queiroz told The Daily Telegraph.

"The best of it is the chance he has in front of him in the coming years. He is too young to rest or relax - this is just the beginning. Thousands of children all over the world see Cristiano and they dream about him, they want to touch him. But Cristiano's game is also about smart work, discipline, commitment. It might be a fantasy to many children except for in computer games, but behind the fantasy there is a lot of reality."

However, Queiroz did admit Ronaldo needs to be more consistent in big games to prove himself the world's best.

"What would you have expected from Michael Schumacher in a Formula One race? It's the same with Cristiano. We expect the best. That is the pressure that we put upon ourselves."
