The Wales international says his side are determined to beat Luis Enriques men on Saturday and will not give up their title fight despite being 10 points behind their rivals.
Gareth Bale has warned Barcelona that Real Madrid have not given up hope of snatching the Liga title from their grasp.
The champions hold a 10-point advantage over third-placed Madrid with just eight matches to go and are enjoying a 39-game unbeaten run across all competitions.
Bale, however, insists his side can still claim their first league title since 2012 if they are able to win Saturday’s Clasico at Camp Nou.
“I believe everything is possible in football. We’re 10 points behind, but we’re going to keep fighting until it’s impossible,” he told reporters.
“On Saturday, we can move to within seven points and you never know what can then happen.
“Obviously every game is important in La Liga, if we win we can gain confidence and take that into the Champions League.”
