Barcelona boss Luis Enrique has called on the supporters to make a big "atmosphere" at the Bernabeu when the team take on Real Madrid in El Clasico on Saturday.

The Catalan giants are currently leading the way at the top of La Liga, three points above their rivals.

Lionel Messi has also been declared fit for the encounter, but it has not been confirmed whether the attacker, who has been absent since September with a knee injury, will play.

"There is nothing more stimulating than El Clasico," Enrique told reporters. "We will see a strong Real Madrid and we hope to be at our level to cause them problems. We like games with atmosphere. We hope tomorrow will be a festival of football."

Barca and Real claimed a win apiece in last season's El Clasico.
