The arrival of Thibaut Courtois at Real Madrid has left both Sergio Ramos and Marcelo concerned over the future of Keylor Navas

Courtois was officially unveiled at a presentation on Thursday after signing a six-year deal with Real president Florentino Perez.

While the Belgian goalkeeper has only just arrived at the Santiago Bernabeu, he is expected to become Julen Lopetegui’s first-choice in goal for the upcoming campaign.

And Don Balon reports that both Ramos and Marcelo are thinking along the same lines and fear what will become of Navas in the future.

The aforementioned duo would prefer to see the Costa Rican remain as Real’s first-choice in goal and feel that he is being unfairly treated by the club.

Although Courtois himself stated that he does not expect to be an automatic starter.

“Nobody at the club has assured me that I’m going to be a starter and I’m simply here to compete,” he said on Thursday.

Navas has consistently performed well for Real over the years following his arrival from Levante in 2014.

The 31-year-old has made 141 appearances for Los Blancos and proved to be a key member of the squad that has won the Champions League for the past three seasons.
