The Brazilian defender has spent the past 15 seasons at the Bernabeu, making over 500 appearances for the Spanish giants in that time.
beIN SPORTS claims that the 32-year-old may be on his way out of Madrid at the end of the season, with Monaco the surprise contenders to sign him.
It is suggested that the French outfit are prepared to hand Marcelo a three-year deal, though he will have to take a hit on his £8m-a-year salary.
Monaco are fourth in Ligue 1, six points adrift of leaders Paris Saint-Germain. body check tags ::
