Casemiro is delighted to be returning to Real Madrid.
Real have re-signed the midfielder after a year away with Porto.
"I'm very happy at getting to return to what I consider my home.
"I'd like to thank Real Madrid and Rafa Benítez for the faith they've shown in me. I'm sure I won't let them down. Playing for Real Madrid is a dream that I don't want to give up on. I'm dying to run out at the Bernabéu again," Casemiro told Marca.
