Real Madrid No2 Aitor Karanka admits they're delighted with their El Clasico wins over Barcelona.
Karanka feels the victories have forced Barca to sit up and take notice.
He said: "We have considerable experience and we know the team Barcelona has. As Mascherano said, a second ago it seemed like a fairytale and now it's quite the opposite. We're continuing to do our job. When things are working well you try to maintain the dynamic and we hope to keep going in this direction and beat Celta."
