Marcelo is prepared to make this his final season with Real Madrid.
Currently club captain, Marcelo has battled for minutes under coach Carlo Ancelotti.
The Brazilian wing-back's contract expires in June and AS says there is an understanding between both parties that it is time to part ways.
Indeed, it hasn't been ruled out that Marcelo could depart in January.
The veteran is a confirmed target for Fluminese at home in Brazil.
