The Spain defender fumed at the officials after a costly 4-3 defeat put Barcelona back in the title race
Ramos was sent-off after referee Alberto Undiano adjudged he had brought down the Brazilian in the area midway through the second half as he raced through on goal.
Lionel Messi scored from the spot to make it 3-3 and the Barca forward – now the all-time leading goalscorer in Clasico history – added another penalty late on to hand the Blaugrana a win which puts them back in the thick of the title race.
"It's always the same. I didn't touch Neymar but there's no point talking about it, it changes nothing," Ramos told AS.
"Everyone can see what happened today. We could have got something from the game but got nothing.
"There are some things you can't fight against. This was pre-meditated."
It was the 19th red card of Ramos’ Madrid career but the Spain international was adamant he had done his best to pull out of the challenge.
"I stopped because I preferred 3-3 rather than a penalty and a sending off," he added.
"Hopefully, we will not meet Undiano for the rest of the season."
