Despite Real Madrid's recent form slide, Marcelo admits his personal performances have been the best of his Madrid career.
The young Brazilian has shone in a more attacking role under coach Manuel Pellegrini this season.
"I feel very good at Real Madrid. I'm in a great moment. I feel useful and I think I am helping Madrid," Marcelo told Marca. "It's nice to know that I can help this team, which is the best in the world without a doubt.
"There is a lot of pressure and a lot of demand, but we know it's the best in the world and always has to be."
