Sergio Ramos slammed the referee after Real Madrid lost to Real Sociedad at home.
The Spanish giants fell back in the race for the La Liga title after falling to a 2-0 defeat at the Santiago Bernabeu. Vinicius Junior was denied a penalty and Lucas Vazquez was sent off.
The winger was shown a second yellow in the second-half before Vinicius was seemingly brought down by Sociedad goalkeeper Geronimo Rulli without being given a decision.
And the Real captain labelled the performance of Spanish referee Jose Munuera 'scandalous' as a result, also slamming the lack of VAR.
"The referee played a big role in things. I've always defended the VAR system, but it has to be improved because what we've seen was scandalous," Ramos said.
"He could have awarded the penalty and then consulted the VAR. After seeing the penalty incidents in the dressing room, all we ask for is fairness."
"There are times when we're punished for our behaviour on the pitch and the referees committee should do the same with the officials. The VAR is in place but you've got to know how to use it and consult it.
'We're motivated and fighting for a La Liga title that'll be tough and it's made all the more difficult when things like this happen."
"When you're out there on the pitch it's so much more difficult because your heart is racing. As the team captain, I always try and help the referees, but tonight's performance was scandalous."
" Lucas Vazquez's sending-off was very harsh. Never before have I seen a player shown a second yellow for something like that, where you're in the middle of the pitch with three Real Madrid players around you."
