There had been speculation that the 30-year-old may join former Real Madrid team-mate Ronaldo at Juventus but the Brazil left-back has moved to quell those rumours.
“I am very happy at Madrid,” said Marcelo in an interview with AS.
“People know what my situation is, I have a lot of years left on my contract, I am very happy here.
“For me it is the best club in the world, I always want to play for the best club in the world.
“It’s nice to touch on this issue because since I came, there are rumours and for me it’s hard to prove that I want to be, and that I can be at Real Madrid, that I give the maximum to play at the best club in the world.”
Marcelo joined Madrid in January 2007 from Fluminense and has gone on to represent the club 456 times, winning four Champions Leagues, four Liga titles and two Copa del Reys.
