Marcelo has missed Madrid's last three matches with the injury that he picked up against Sevilla on September 26.
However, the left-back is expected to return to the XI for the clash with Levante on October 20, having confirmed that he is back in full training with his teammates.
"I'm fine, almost 100%," Diario AS quotes Marcelo as saying. "I have now trained with the ball for the past two days after going through physical tests and the international break has arrived at the right time for me."
Los Blancos are without a win in their last four matches in all competitions, suffering three defeats in the process.
