Barcelona defender Gerard Pique says they won't underestimate Real Madrid in today's El Clasico.

Real go into the clash struggling for form.

"We are in very positive form and winning a lot of games," Pique said. "Most of all, we have three very strong players up front and we're competing well at the back.

"We are all excited about the Clasico and hoping to get all three points from the game... You feel stronger and more confident on the back of a run like the one we've been having.

"This isn't their (Real's) best moment of the season. But the form book goes out the window for the Clasico. Each side has a 50% chance of winning.

"They have Cristiano (Ronaldo) and (Gareth) Bale, two players that are very powerful, very fast, very dangerous in the one-on-one and who score goals. (Karim) Benzema gives them balance."
