The Los Blancos midfielder compared reactions to two controversial games, one involving Real Madrid and one featuring Barcelona.

Seems like the rivalry between Barcelona and Real Madrid has hit a new low, since Spanish journalists don't seem to be capable of separating their allegiance to a team while doing their job.

This was exposed earlier today by Isco, who posted a video on his Twitter feed, where he compared reactions from a journalist during Wednesday's game between Real Madrid and Juventus to those he had in the UEFA Champions League match featuring PSG and Barcelona.

Both games were filled with controversial calls, but the journalist seemed to have a tendency to overlook some decisions that saw Barcelona win that tie.

Have a look at the video. Below, we will provide a translation for each portion of the footage.

"One job, two different judgements. Shameful!"

"Good evening, welcome to Partidazo de la COPE after yet another magical UEFA Champions League night. Real Madrid made it to the tournament's semi-finals, and they accomplished that via a world-wide scandal. After 93 minutes, with Juventus winning 3-0, referee Michael Oliver decided to award a penalty due to a foul by Benatia against Lucas Vázquez. We don't know if he noticed a kick, a shove or both against the Spaniard. This incident will go down in history, and we'd like to know what our reaction would be if this happened to a Spanish side. Real Madrid had a baffling game, without controlling the ball, and only a miracle saw them reach the semis. Those who don't support Real Madrid are considering this as a robbery. We will never reach an agreement on whether it was a good call or not."

After 1:02 minutes, Castaño starts speaking about Barcelona's game vs PSG.

"Good evening, this is not a historical date for football or for Barça's history, this is a historical day for the world of sports. What happened today at Camp Nou can only be labeled as historical. We're here live to talk about Barcelona's heroic deed, a true game to remember as Barcelona beat PSG 6-1. Barcelona makes it through after following an incredible 'script'. For those who didn't watch the game, this isn't a regular 6-1 score, it can't be paired up with any other scoreline of the sort, trusting that you've witnessed some of those in your life."
