"We have arrived at a moment in the season where there is no difference in points between us and Barcelona and any error can cost the Liga title. We are going into this Clasico with a lot of ambition and I believe the match will be key in defining how one wins a title," said the Sevillan defender.
For Ramos, Madrid's best weapon will be their focus in the match, and he thinks it fundamental for his side to "concentrate and respect their rivals".
"We have to be strong, try to do damage along the wings with the speed of the players we have, maintain possesion of the ball, and try to commit very few errors, above all in defence," said the defender.
Ramos believes that no matter who Barca coach Pep Guardiola fields on the pitch, "Barca will not change their style or their form of play".
"It is evident that they have created an identity, their own style of play that remains no matter who plays, whether it be Busquets, Xavi or Andres Iniesta. With this knowledge, we go out with very clear ideas on how to stop them."
Above all, Ramos believes that Lionel Messi is Barca's biggest threat "not just now, but he has been for some time". "We have to make things very difficult for him because he is a player that can make the difference. Although Barcelona can have good matches and bad matches, Messi continues to be the difference-maker. He is Barca's most fearsome player."
Finally, Ramos declared that he hopes to give "a lot of happiness to the fans" as Los Blancos prepare to reverse their fortunes against their arch-rivals; Barcelona have won the past three consecutive Clasicos.
