Madrid were only able to scrape a point after substitute Isco equalized for 'los blancos', but Marcelo denied that Ronaldo's departure had anything to do with the disappointing result.
He reminded the media that the club has coped with high-profile departures in the past.
"I think supporters also often remember Raul, Zidane... Not only Cristiano," he said.
"The draw is a bit disappointing. We were hoping for a fairer outcome, which would have been to win the game.
"We gave it our all to do so and we improved in the second half but we have to move on from this game and think about the next."

Talking about the match itself, Marcelo believed his team should have been more patient.
"We had a lot of the ball and created chances but it just wouldn't go in for us. We've got a fantastic team, we played well, but we couldn't win the game," he continued.
"We didn't want to drop any points here. We also lacked a bit of patience.
"After going behind, we tried to get on top quickly, but that's the way things go in football. We came very close to getting the three points. We're firing on all cylinders right now."
