Barcelona coach Luis Enrique insists there's no favourite going into their clash with Real Madrid.
Barca can go clear of Real with victory.
Enrique said: "There are no clear favourites in games like these. These are two top quality teams with a lot at stake. But we do have home advantage and playing in front of our own fans always gives us that extra boost.
"We won't fall into the trap of thinking it will be easy. We know the defence will be under serious pressure at times and we hope the fans can focus their excitement on helping us when things like that happen.
"This is a nice chance to put some space between us. We'll need to play our best, and be solid both in defence and attack. And supported by the Camp Nou."
