Kaka says Raul remains a leader inside the Real Madrid dressing room.
The former AC Milan star admits he is also taking on greater responsibility since arriving in the summer.
Kaka said: "Raul and Cristiano (Ronaldo) are the leaders. I'm in the middle of the big two. I talk to them. I talk a lot to Raul to ask about Madrid and Spain.
"Cristiano s a great, great player and a very gracious person. We are friends and talk about everything. He's a phenomenon."
