Courtois was unveiled on Thursday afternoon after completing a medical with the Champions League title holders.
The 26-year-old completed a move to Real on transfer deadline day as he signed a six-year deal after leaving Chelsea.
The former Atletico shot-stopper left the Blues for £35 million in a deal that included midfielder, Mateo Kovacic leaving Madrid on a season-long loan.
Speaking after completing the latest move, Courtois told Real Madrid’s official website: “I wanted to be closer to my family. I want to say thank you to everybody who has made this possible, particularly the mother of my children.
“Although we are no longer together you remain a very special person for me. Today I am just another Madridista. I am one of you. Hala Madrid!”.
Courtois added: “Arriving at the best club in the world is not an easy thing. I have worked very hard to get here. I have always dreamed of this moment since I was a kid.” SHARE THIS STORY USING ANY OF THE BUTTON BELOW ⬇ PLACE YOUR TEXT ADVERT BELOW ⬇⬇⬇
