Real are eight points behind current pace setters Barcelona and Atletico Madrid.
Early season defeats against Sevilla and Getafe have left Los Blancos playing catch-up, although a 5-0 victory at Real Mallorca last weekend indicated Jose Mourinho's men are getting back to top form.
"The win against Mallorca was important," Ramos said. "It's a tough place for us to go and get a result. We're up there and will keep on fighting.
The triumph at the ONO Estadi leaves Madrid in fourth place but the club are in no mood to give up the title to their bitterest rivals.
"We are motivated by the challenge to catch up with Barcelona," Ramos added.. "We're going to fight for the league title right to the end and we expect to be in with a shout.
"Right now there are two teams on top of their game, Barcelona and Atlético de Madrid, but if we keep winning our games we'll put them under a lot of pressure."
And midfielder Jose Callejon believes the team spirit at the club will drive them to glory.
"The dressing room is united and we all have a lot of faith in each player we have alongside us. That's the important thing, that we trust in each other," Callejon told Bwin.
"To be able to say at the end of the season that all the players have given their all on the pitch, that we have put our hearts and souls into all the games and training sessions. Hopefully we'll give the fans a lot to celebrate and win titles."
