Juan Carlos was thrilled with his Real Madrid debut on Sunday for the win over Deportivo La Coruna.
The young midfielder became the first player from the Castilla to be handed a senior chance by coach Jose Mourinho.
"Mourinho is a very nice guy. In communication he does very well, as he speaks many languages. Portuguese, English, French, Brazilian and smells really good (laughs).
"Before going on, Mourinho asked me if I was scared, and I said no. He told me to play with ambition and audacity."
