Barcelona defender Gerard Pique has voiced his belief that are no favourites whenever his side and Real Madrid meet.
The two arch-rivals are set to clash next week's Copa del Rey quarter-final, and Pique believes that such encounters are too tight to call.
"There are no favourites between Barca and Real Madrid," the 24-year-old told El Larguero. "These matches have a lot of tension, where you get physically and mentally exhausted.
"Whoever loses is a little diminished, but for now we have to play Real Betis in the league, and then prepare for the big match."
Meanwhile, Pique has pledged a message of support to Andreu Fontas, who suffered a ligament injury during his side's 2-1 victory over Osasuna in Thursday's Copa del Rey second leg last-16 clash.
"I was very worried. We have to try to help and move forward because he is a very strong player."
Real Madrid host Barcelona in the Spanish capital on January 18 in the quarter-finals of the cup competition, before the two sides meet at Camp Nou a week later.
