Real Madrid signing Thibaut Courtois says he expects to start ahead of new teammate Keylor Navas.
However, the Belgium goalkeeper is confident he'll be friends with the Costa Rican.
He said, "When I came to Chelsea I did it to replace (Petr) Cech, I still talk to him today, the goalkeepers are part of a dressing room and they are also friends, I will do everything so that there is a good feeling within the group.
"I will help Madrid win matches and trophies."
On Real legend Iker Casillas, Courtois feels he has the same mental strength.
He added: "When I saw him play, what struck me the most is that a goalkeeper at 18 years old, with that pressure, performs like that, you have to be mentally strong, I made my debut with Genk at 16, at Atlético with 19 ... I think that's very important, and his ability between sticks was impressive."
