Ronaldo left Real after the World Cup for Juventus, however Marcelo says he knew his former teammate's plans before the Champions League final in Kiev.
He told Esporte Interactivo: "We were in training before the final and he said: 'I'm leaving, this is my last game here'."
Meanwhile, Marcelo also revealed Gareth Bale still can't speak Spanish despite six years in Madrid.
After the departure of Ronaldo and Kiko Casilla, Marcelo says he is now lonely in the dressing room.
"Now I have no one by my side, I have Bale on the other side, but Bale does not speak, he only speaks English, we speak with gestures and say 'hi, hello and good wine'."
