Real Madrid goalkeeper Thibaut Courtois has taken aim at Barcelona ahead of Sunday's El Clasico.

Amid Barcelona's Negreira case, Courtois called for "honesty" from match officials.

He said, "In the locker room we didn't talk about anything. We are far from that.

"We just hope that the referee who whistles is honest. You can be wrong, but be honest."

The Belgian also stated: "Yesterday Hernández Hernández was in the VAR and asked for a hand from Leipzig but I want to ask him about a clearer hand that was in the derby and he did not whistle, why?"
