"Mario is a very sweet boy. I already knew him a little bit before and we all know his qualities. I am here to support him, help him to grow and he seems very eager to work with me. I am confident.
"I think it is very important for players and Coach to communicate and collaborate, as the more information we all have, the better a job we can do.
"Seeing Kaka here means I've found another old friend. I know that I can count on him above all as a person. He also proved his worth on the pitch again and will set an example for his teammates.
"I also know Nigel De Jong, as there's a photograph of me playing for Ajax with him as a ball boy. He's an exceptional guy and a great professional, so I'm happy to meet him again here."
