Real Madrid have been told to be careful with Marcelo as he "gets fat easily," according to former manager Bernd Schuster.
The German worked with Marcelo during his one season in charge of Los Blancos in 2007-08 and spoke about the Brazilian with Onda Cero's El Transistor programme (h/t Marca).
"In every team you have three or four players who have a lot of problems with their weight, and in my time Marcelo was one of them," Schuster said. "He gets fat easily; you have to be careful and keep on top of him, especially when he is injured.
