Sergio Ramos has warned his Real Madrid teammates that they have no margin for error in the second part of their La Liga campaign.
Los Blancos currently sit third in the table, five points behind Barcelona and Atletico Madrid, who have collected 46 points from their 17 matches.
Real have lost just twice this season, but are already playing catch-up ahead of the second part of the campaign.
"We've dropped points along the way but this is a very exciting title race. Barcelona and Atletico don't allow us any margin for error and that forces us to be at our best in every game," Ramos told AS.
Real are next in league action against Celta Vigo at the Bernabeu on January 6.
