Barcelona midfielder Sergio Busquets insists they're not taking Real Madrid lightly tonight.

Barca go into the game eight points clear of Real.

"Iker Casillas is one of the best goalkeepers in the world and has had a phenomenal career," Busquets said.

"Sergio Ramos has great qualities and will play wherever you play, with or without the ball. And he's a great marker.

"Pepe is a key player and very powerful, Xabi Alonso is the one who directs and manages Madrid's game. His long balls behind the opponents' defence are dangerous and create a lot for Madrid.

"Mesut Ozil is a quality player with a great final pass, Karim Benzema also has a lot of quality in addition to goals and then there is Cristiano Ronaldo. He's a fantastic player, very powerful.

"We have to try to stay one step ahead of him, it will not be easy.

"All in all, they're a great team, great players and we have to be at our best."
