Real secured maximum points to maintain their perfect start to the new LaLiga season with Sergio Ramos, Gareth Bale and a Karim Benzema brace helping them overcome a 16th minute strike from the home side.
However, veteran wing-back Marcelo's reaction to being subbed mid-way through the second half by head coach Julen Lopetegui raised a few eyebrows.
"I was surprised by the substitution but I respect the decision of the coach, I wanted to continue because I felt 100%," Marcelo said after the game, as quoted by Marca.
When prompted over his opinion of the departure of close-friend and club-record scorer Cristiano Ronaldo, the Brazil international played down the recent media reports claiming they need a new high-profile signing.
"We are on the right road and I am sure we are going to improve with each game. We played well today and we got the three points.
"Cristiano is the best in the world so it is obvious we will miss him but Bale and Benzema are also very good."
