The Blancos defender saw a goal controversially disallowed during Saturday's 3-2 win over Valladolid, and has slammed the level of officiating in Liga matches
The Spain international saw a goal wrongly ruled out for offside as his side came from behind to claim a 3-2 win over Valladolid, and although Mesut Ozil later sealed the win, the defender is far from happy.
"It was a goal and it annoys me that they ruled it offside, even though in the end we got the three points," the 26-year-old was quoted as saying by AS.
"With another result the consequences would be very different. They've harmed us in more than one match now. It's about time they make a mistake in our favour."
Los Blancos currently sit third in La Liga with 32 points from 15 games and Ramos stressed that any small error could strike a blow against their chances of catching Barcelona, who have an eight point lead over their rivals.
"The distance between us and the leaders is a big one. Any slip would make things impossible and we wouldn't like that to be down to the officials."
