"Thank you to Mr Di Stefano and the president. I am very proud to play for Real Madrid. Many goals. Thank you to everybody," Huntelaar stated.
Calderón then explained that the club had planned to secure the services of the 25-year-old goalscorer in the summer, but the injury to Ruud van Nistelrooy meant that they had to bring forward that idea.
Huntelaar is the sixth Dutch player in the Madrid squad with Van Nistelrooy, Wesley Sneijder, Rafael Van der Vaart, Arjen Robben and Royston Drenthe all with the club alreday.
"Some of the players I already know from Ajax. It's going to be easier to adapt here than at a club where I don't know anyone," the striker added in English.
"Real Madrid is the biggest team in the world. I'll be doing all I can to help us catch up."
