The Brazilian marked five years at the club with the 5-1 victory over Granada last night.
The 23-year-old has established himself as Real Madrid's first-choice left wing-back with some saying he has even become one of the best in world football. The former Fluminense player expressed his love for the club following his side's win.
"I want to stay here many more years. I've always enjoyed myself here and today was very special for me, especially due to the victory," said Marcelo.
"I give my all in every training session and match.
"I feel very proud to wear this shirt. I fight to play many more games."
Marcelo joined Real Madrid in 2007.
