But the 30-year-old said leaving the Santiago Bernabeu was not something he had ever thought about.
"It's never entered my mind to leave and look for another option," Marcelo told Club del Deportista.
"I have always done everything possible to stay at Real Madrid and I've never thought about playing time.
"If I had 15 minutes in every game, I’d give everything in those 15 minutes to play more and win more."
The former Fluminense defender remembered just how the move happened, saying he initially did not believe it.
"The move all happened very quickly. At first I thought it was a joke," Marcelo said.
"I always saw Madrid as a huge club. Then all of a sudden I was part of a team with players I had only seen on television or in video games.
"It was pretty amazing."
